Heating Circuit (X)
16
Operating mode
Auto = Automatic/Normal mode using the set times.
Reference Value = Fixed flow temperature regardless of the outdoor temperature. The desired flow temperature must be set in
Menu 4.3 .
Reference value = Menu 4.4 can be used to set specific flow temperatures for the next 14 days. After 14 days, the reference tem-
perature of the 14th day is used continuously until the operating mode is changed. Different temperature values can be set in
menu 4.4 for every individual day.
Off = Heating circuit is switched off (except Frost protection)
S/W Day
Summer / Winter changeover in daytime mode
If this value is exceeded at the outdoor sensor the controller automatically switches the heating circuit off = Summer mode. If the
outdoor temperature drops below this value, the heating circuit is switched on again = Winter mode.
In addition to the operating times in normal daytime operation, this setting is also valid for times with activated comfort.
S/W Night
Summer/Winter changeover in night-time mode
If this value is exceeded at outdoor sensor S1 during the nighttime mode times, the controller automatically switches the heating
circuit off = Summer mode. If the outdoor temperature drops below this value, the heating circuit is switched on again = Winter
mode.
Curve
Type and slope of the heating characteristic curve
The characteristic curve is used to control the heat dissipation of the heating circuit relative to the outdoor temperature. The
demand for heat differs due to factors such as the type of building, heating, insulation and outdoor temperature. For this reason,
the controller can operate with a normal straight curve (setting simple) or split curve (setting split‘).
If ‚simple‘ is selected, the curve is adjusted using the graphic diagram. While setting the slope, the controller also shows the slope
value and the calculated target flow temperature at -12 °C as a reference point.
If ‚split‘ is selected, the curve is set in the following steps:
1. Slope over outdoor temperature for change
2. Outdoor temperature for slope change
3. Slope below outdoor temperature for change
While setting the slope, the controller also shows the slope value and the calculated target flow temperature at -12 °C as a ref-
erence point. In case of repeated adjustment of the split curve, the settings appear in reverse order.
The diagram shows the influence of the selected characteristic curve
steepness (standard curve) on the calculated reference flow
temperature of the heating unit. The correct characteristic curve is determ-
ined by defining the intersection point of the maximal calculated flow tem-
perature (=design temperature) at minimal outdoor temperature.
Example: The design temperature of the heater 60 °C flow at lowest out-
door temperature according to calculation of heat requirement
-12 °C. The intersection point renders a slope of 1.2 as the setting.
Day Correction
Parallel characteristic translation
The day correction causes a parallel shift of the heating curve during daytime operating hours, because with certain outdoor tem-
peratures the building might not be optimally heated with the set heating curve. With a non-optimised heating curve, the following
situations frequently occur: hot weather = room too cold/cold weather = room too hot. In this case, the slope of the curve should
be reduced stepwise by 0.2 points and increases the day correction
by 2 ... 4 °C each.
Night Correction
Parallel characteristic translation
The night correction produces a parallel translation of the heating characteristic during the nighttime operating hours. If a neg-
ative value is set for the night correction, the reference flow temperature is lowered accordingly during the nighttime operating
hours. In this manner, primarily at night, but also during the day when no-one is at home, the room temperature is lowered, thus
saving energy. Example: A day correction of +5 °C and a night correction of -2 °C produces a reference flow temperature in night-
time operation that is 7 °C lower.
17
troller: 10 %= 4 °C 5 X 4 °C= 20 °C. Accordingly, 20 °C are added to the reference flow temperature, giving 60 °C. If the value is
higher than the one set in max. flow temp, the resulting temperature is the one set in max. flow temp.
Room Reference (Day)
The desired room temperature for day mode. As long as this temperature is not reached, the reference flow temperature is
raised and/or lowered according to the percent setting in room controller‘. If ‚room controller‘ is set to 0 %, this function is deac-
tivated.
Room Reference (Night)
The desired room temperature for night mode. As long as this temperature is not reached, the reference flow temperature is
raised and/or lowered according to the percent setting in room controller‘. If ‚room controller‘ is set to 0 %, this function is deac-
tivated.
In the modes ‚Set point‘ and ‚Set point program, the room controller has no influence.
Thermostat (X)
The room controller is selected here. If no room controller is connected and a room controller is connected via the CAN Bus,
another room controller can be selected here. The CAN bus ID of controller is shown in Menu 6, ‚Service Data‘ under ‚CAN Bus
ID‘. In °CALEON see the CAN Bus ID in the expert menu under Network. Choose the Room Controller with the CAN Bus ID of
the corresponding controller.
Sensor Typ
If a sensor input is connected to a room controller, it must be set here whether it is a room temperature sensor (RC20) or a switch-
ing contact.
Mixer
This menu contains all the settings concerning the mixer of heating circuit 1
Direction
Direction of the mixing valve can be set here.
Mixer turn time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow
temperature
Mixer off factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is ‚1‘, the normal pause time is
used, 0.5‘ will use half the normal pause time. Setting the pause factor to ‚4 would quadruple the pause time.
Mixer increase
If the temperature rises very fast, this value is added to the measured flow temperature so that the mixer’s reaction is stronger. If
the measured temperature does not rise any more, the measured value is used again. The measurement occurs once every
minute.
PV contact
This sensor input could be used as a PV-contact of Photovoltaic-System.
This sensor is observed to "short circuit" (PV-Contact closed).
If the PV-Contact is closed, the mode of this function is changed to "comfort" and operate
This also applies in the case that the mode "comfort" of the function currently has no time release.
Information about the operation and the connection of PV-contact, refer to the technical description of your PV sys-
tem.
Settings Domestic Hot Water (DHW)

DHW hysteresis
The DHW charge and heat request are shut down if the temperature at the DHW sensor reaches the value set under “see " Hot
water minimum " on page 19“ / “see " DHW reference " on page 19“ plus the heating set here.
Buffer DHW load
DHW load from the buffer
The DHW load from the buffer storage is turned on if the temperature on the buffer sensor is at least 8°C warmer than at the DHW
sensor. The DHW load from the buffer storage is shut down if the temperautre at the buffer sensor is only 4 °C warmer than at the
DHW sensor or if the temperature at the DHW sensor has reached the value set under see " Hot water minimum " on page 19 or
see " DHW reference " on page 19.

prevent seizing of the pump/valve after long periods of inactivity.
ABS R(X)
Activation (daily, weekly) of the anti-lock protection to a relay (X) at 12:00 for 5 seconds.
Frost Protection
If the temperature on the outdoor sensor drops below 1 ° C and the heating circuit is switched off , the heating circuit is auto-
matically switched on if antifreeze is activated and the reference flow temperature will be set to the minimum flow temperature set
under see " Min. Flow " on page 28. As soon as the outdoor temperature exceeds 1 ° C, the heat circuit is switched off again.
Switching the frost protection function off or setting the minimum flow temperature too low can lead to severe damage
to the system.
Discharge Protection

7. Special Functions
Used to set basic items and expanded functions.
The settings in this menu should only be changed by a specialist.
Program selection
Here the hydraulic variation fitting to the respective use case is selected and set.
The program selection normally occurs only once during the first entry into service by a specialist. An incorrect pro-
gram selection may lead to unpredictable errors.
Pump settings
Settings from the 0-10V or the PWM pump can be made in this menu.
When this menu is selected, you may receive a request to save the speed settings.
Signal type
The type of device to be controlled is set here.
0-10V: Controlled by a 0-10V signal.
PWM: Control by means of a PWM signal.
Pump
In this menu, the preset profiles for the pump can be selected or under “manual all settings can be done personally. The settings
can still be changed after a profile has been selected.
Output Signal
In this menu, the type of pump is set: heating pumps have the greatest output with a small input signal, solar pumps in contrast
have very little output with a small input signal. Solar = normal, heating = inverted. For 0-10 V pump always choose the "Normal"
setting
PWM / 0-10V off
This voltage / this signal is emitted if the pump is turned off (pumps
with cable break detection need a minimal voltage / minimal signal).
PWM / 0-10V on
This voltage / this signal requires the pump in order to turn on and to run at a minimum speed.
PWM / 0-10V max.
With this value, the maximum voltage level / maximum frequency can be specified for the highest speed of the energy saving
pump, which is used, for example, during the flushing or manual operation.
Show signal
Represents the set pump signal in a graphic and text overview.
Speed control
If the speed control is activated, itXHCC offers the possibility through a special internal electronic system to change the speed of
pumps depending on the process. The relay R1, R2 and the Pwm and 0-10V outputs can work with the speed controlled.
22
This function should only be activated by a technician. Depending on the pump being used and the pump level, the
minimum speed may not be set too small, because the pump or the system may be damaged. The specifications from
the affected manufacturer must be observed for this! When in doubt, the min. speed and the pump level should be set
too high instead of too low.
Variant
The following speed variants are available here:
Off: There is no speed regulation. The connected pump is only turned on or off with full speed.
Mode M1: The controller changes to the set max. speed after the purging time. If the temperature difference T between the ref-
erence sensors is below the set switch on temperature difference ∆T R1, the speed will be reduced. If the temperature difference
between the reference sensors is above the set switch on temperature difference ∆T R1, the speed will be increased. If the con-
troller has decreased the speed of the pump to the smallest level and the ∆T between the reference sensors is still only ∆Toff, the
pump will be turned off.
Mode M2: The controller changes to the set min. speed after the Speed. If the temperature difference ∆T between the reference
sensors is above the set switch on temperature difference ∆T R1, the speed will be increased. If the temperature difference T
between the reference sensors is below the set switch on temperature difference ∆T R1, the speed will be reduced. If the con-
troller has decreased the speed of the pump to the smallest level and the ∆T between the reference sensors is still only ∆Toff, the
pump will be turned off.
Mode M3: The controller changes to the set min. speed after the Speed. If the temperature on the reference sensors is above the
set value to be set in the following, the speed will be increased. If the temperature on the reference sensors is below the set value
to be set in the following, the speed will be reduced.
Purging time
For this time, the pump runs with its full speed (100%) in order to guarantee a secure start-up. Only after expiration of this purging
time will the pump have a controlled speed and will switch, depending on the set variant, to the max. or min. speed. Speed.
Sweep time
With the control time, the inertia of the speed control is determined in order to prevent strong temperature deviations as much as
possible. The timespan is entered here, which is needed for a complete cycle from minimum speed to maximum speed.
Max. Speed
The maximum speed of the pump is determined here. During the setting, the pump runs in the respective speed and the flow can
be determined.
The specified percentages are variables, which may deviate more or less strongly depending on the system, pump
and pump level. 100% is the maximum possible power of the controller.
Min. Speed
The minimum speed of the pump is determined here. During the setting, the pump runs in the respective speed and the flow can
be determined.
The specified percentages are variables, which may deviate more or less strongly depending on the system, pump
and pump level. 100% is the maximum possible power of the controller.
Sensor Calibration
Deviations in the temperature values displayed, for example. due to cables which are too long or sensors which are not posi-
tioned optimally can be compensated for manually here. The settings can be made for each individual sensor in steps of 0.5 °C.
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect meas-
urement values can lead to unpredictable errors.
Relay functions
Free relays, i.e., relays not used in a basic scheme, can be assigned to various additional functions. Every additional function can
only be assigned once. See all additional functionssee " Function overview " on page 27.
R3 to R6: Mechanical relay 230V
R7: Potential free relay
V1 and V2: PWM and 0-10 V output
Please pay special attention to the relay’s technical information (see "Specifications“).
The symbols shown here are displayed on the main overview screen when the special function is activated.
23
Extension Box
An optional extension box can be activated.
Heat quantity
Constant flow
If “Constant flow is activated as the type of heat quantity metering, the approximate heat from the manually entered values for
antifreeze, its concentration and the flow from the system and the measured sensor values from the collector and storage are cal-
culated. Additional information about antifreeze, its concentration and the flow of the system is required. Additionally through the
setting offset T, a correction factor can be set for the heat quantity collection. Since the collector temperature and the storage tem-
perature can be used for the heat quantity metering, depending on the system, there may be deviations from the displayed col-
lected temperature to the actual previous temperature or the displayed storage temperature to the actual return temperature.
Through the setting Offset ∆T, this deviation can be corrected.
Example: displayed collector temperature 4C, read previous temperature 39°C, displayed storage temperature 30°C, read
return temperature 31° means a setting of -20% (displayed ∆T 10K, actual ∆T 8K => -20% correction value)
The heat quantity data in the “Constant flow mode only consists of calculated values for the functional inspection of
the system.

Function overview
Heating Circuit (X)
S/W Day
Summer / Winter changeover in daytime mode
If this value is exceeded at the outdoor sensor the controller automatically switches the heating circuit off = Summer mode. If the
outdoor temperature drops below this value, the heating circuit is switched on again = Winter mode.
In addition to the operating times in normal daytime operation, this setting is also valid for times with activated comfort.
S/W Night
Summer/Winter changeover in night-time mode
If this value is exceeded at outdoor sensor S1 during the nighttime mode times, the controller automatically switches the heating
circuit off = Summer mode. If the outdoor temperature drops below this value, the heating circuit is switched on again = Winter
mode.
Curve
Type and slope of the heating characteristic curve
The characteristic curve is used to control the heat dissipation of the heating circuit relative to the outdoor temperature. The
demand for heat differs due to factors such as the type of building, heating, insulation and outdoor temperature. For this reason,
the controller can operate with a normal straight curve (setting simple) or split curve (setting split‘).
If simple‘ is selected, the curve is adjusted using the graphic diagram. While setting the slope, the controller also shows the slope
value and the calculated target flow temperature at -12 °C as a reference point.
If split‘ is selected, the curve is set in the following steps:
1. Slope over outdoor temperature for change
2. Outdoor temperature for slope change
3. Slope below outdoor temperature for change
While setting the slope, the controller also shows the slope value and the calculated target flow temperature at -12 °C as a ref-
erence point. In case of repeated adjustment of the split curve, the settings appear in reverse order.
The diagram shows the influence of the selected characteristic curve
steepness (standard curve) on the calculated reference flow
temperature of the heating unit. The correct characteristic curve is determ-
ined by defining the intersection point of the maximal calculated flow tem-
perature (=design temperature) at minimal outdoor temperature.
Example: The design temperature of the heater 60 °C flow at lowest out-
door temperature according to calculation of heat requirement
-12 °C. The intersection point renders a slope of 1.2 as the setting.
Day Correction
Parallel characteristic translation
The day correction causes a parallel shift of the heating curve during daytime operating hours, because with certain outdoor tem-
peratures the building might not be optimally heated with the set heating curve. With a non-optimised heating curve, the following
situations frequently occur: hot weather = room too cold/cold weather = room too hot. In this case, the slope of the curve should
be reduced stepwise by 0.2 points and increases the day correction
by 2 ... 4 °C each.
Night Correction
Parallel characteristic translation
The night correction produces a parallel translation of the heating characteristic during the nighttime operating hours. If a neg-
ative value is set for the night correction, the reference flow temperature is lowered accordingly during the nighttime operating
hours. In this manner, primarily at night, but also during the day when no-one is at home, the room temperature is lowered, thus
27
saving energy. Example: A day correction of +5 °C and a night correction of -2 °C produces a reference flow temperature in night-
time operation that is 7 °C lower.
Comfort Temperature Boost
Parallel characteristic translation
The comfort temperature boost is added to the set day correction. In this manner it is possible to carry out quick heating and/or
raise the temperature of living spaces at a certain time each day.
Min. Flow
The minimum flow temperature is the lower limit of the heating curve, and by this, the reference flow temperature of the heating cir-
cuit. In addition to that, the minimal flow temperature is the reference flow temperature for the frost protection function.
Max. Flow
This value is the upper limit of the reference flow temperature of the heating circuit If however, the temperature of the heating cir-
cuit exceeds the set value, the heat circuit shuts down until the temperature falls below this value. The system purged for 30
seconds every 5 minutes.
The customer must provide an additional limiting thermostat which is connected to the pumps in series (eg underfloor
heating) for safety.
Reference/Actual -
Switch on hysteresis for additional heating
This setting determines the allowed undershoot of the heating circuit temperature below the calculated reference fl ow tem-
perature. If the heating circuit flow temperature and the storage temperature drop below the reference flow temperature by this
value, the additional heating will start the additional heat source after a 1 minute delay.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Reference/Actual +
This setting determines the allowed undershoot of the heating circuit temperature below the calculated reference flow tem-
perature at the storage sensor (see - storage HK”) or flow sensor. If the temperature on the storage sensor HC or, if this was not
selected, on the flow sensor, exceeds the reference flow temperature by the value set here, the heat request will be turned off.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Reference/Actual +
This value determines the acceptable underflow of the heating circuit temperature beyond the calculated reference flow tem-
perature at the buffer sensor or flow sensor. If the temperature at the buffer sensor exceeds the reference flow temperature by the
value set here, the heating request is deactivated.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Variant
Condition for shutting off the heating circuit pump
In the mode Flow (VL), the pump is shut down if the reference temperature is exceeded. In the summer/winter mode (SW), it is
shut down in the winter mode at Tmax, in the summer mode the heating circuit pump is shut down in general.
The sensor should be placed in the return line in the VL mode.
Turn off HC
Summer: HC turns off when the summer/winter changeover (outside temperature) is exceeded.
Summer + Room: HC is turned off when the summer/winter changeover (outside temperature) or the room setpoint temperatures
are exceeded.
Room hysteresis
Steps for the reactivation of the heating circuit at room temperature.
Buffer sensor
Input of heating circuit buffer sensor

Direction
Direction of the mixing valve can be set here.
Mixer turn time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow
temperature
Mixer off factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is 1‘, the normal pause time is
used, 0.5‘ will use half the normal pause time. Setting the pause factor to 4‘ would quadruple the pause time.
Mixer increase
If the temperature rises very fast, this value is added to the measured flow temperature so that the mixer’s reaction is stronger. If
the measured temperature does not rise any more, the measured value is used again. The measurement occurs once every
minute.

Anti Legionella
With the help of the anti legionella function (hereinafter referred to as: AL), the system can be heated up at selected times in order
to free it of legionella.
In the delivery state, the anti legionella function is switched off.
Antilegionella function is not shown in the menu “Protective functions”. It is instead shown as submenu of the cor-
responding special function. Special functions with AL include: Solar, burner, circulation and compressor (compressor
on page 40).
Antilegionella function is not shown in the menu “Protective functions”. It is instead shown as submenu in the cor-
responding settings of the special function. Special functions with AL include: solid chamber (see " Solid fuel boiler "
on page 32), solar (see " Solar " on page 35), burner (see " Burner " on page 32), circulation (see " Circulation " on
page 38) and compressor (see " Compressor " on page 33).
As soon as it has heated up with “AL” turned on, information with the date will be shown in the display.
This anti legionella function does not offer any secure protection against legionella, because the controller requires an
adequate added amount of energy and the temperatures cannot be monitored in the entire storage area and the con-
nected pipe system. For secure protection against legionella, a heating up to the requried temperature as a well as a
simultaneous circulation of water in the storage and pipe system must be guaranteed through energy sources and
external control devices.
During the operation of the anti legionella function, if applicable, the storage is heated above the set value “Tmax”,
which may lead to scalding and system damage.

No: It is cooled down to the reference flow temperature + hysteresis, the temperature in the buffer storage is ignored.
By default, sensor S2 is set as the buffer sensor. Theassigned sensor for this function can be changed in the settings for the heat-
ing circuit 1 see " Buffer sensor " on page 28.
Dew point correction
The internal dew point curve is moved parallel with this value. The dew point calculation is used to calculate at which room tem-
perature there is an undesired condensation (precipitation) at the currently measured humidity. This calculated room temperature
will not be undershot with the cooling system and therefore represents a temperature lower limit for the cooling system.
The calculated room temperature can be moved by up to 10 °C with the dew point correction.
Example 1: You determine that there is precipitation with the default value,
so you increase this correction value.
Example 2: Condensation/precipitation can be ignored, instead a
stronger cooling system is required. You therefore decrease this correction value.
In case of reduction of the calculated temperature with the help of dew point correction condensation / perspiration / pre-
cipitation can occur, which, among other things, may cause the formation of mold.
Room reference cooling
Reference value for the temperature in the room.
The controller adjusts the flow so that this temperature is reached in the room.
If the value set here is exceeded, the relay will turn on the cooling function if this is approved for the time.
The relay of the cooling function is turned off if the reference value hysteresis is not met.
Delay
Switch delay of the heat and cooling request. In order to prevent the heat or cooling request to be activated if there are heat devi-
ations, the corresponding relay is switched up ot 5 minutes before the switch conditions occur.
Periods
Cooling activity times
Here the desired periods are set in which the cooling function is approved. For each weekday, three times can be specified, fur-
thermore, you can copy individual day to other days. The cooling function is shut down outside of the set times.
34
Dehumidifier
Operating mode
The operating mode of the dehumidifier function can be set here.
Summer: In the summer operating mode, the dehumidifier turns on when the target humidity is exceeded, if the S/W day tem-
perature is exceeded and the function is approved.
Summer+Circ.: In the summer+circulation operating mode, the dehumidifier turns on when the target humidity is exceeded, if the
S/W day temperature is exceeded and the heating circuit pump is running and the function is approved.
Year round: In the year round operating mode, the dehumidifier turns on when the target humidity is exceeded if the function is
approved.
Reference humidity
Reference value for the humidity in the room.
If the value set here is exceeded, the relay will turn on the dehumidifier if this is approved for the time. The dehumidifier is turned
off if the reference value hysteresis is not met.
Hysteresis
Hysteresis of setpoint for the humidity.
Dehumidifier periods
Approval time for the dehumidifier
Here the desired periods are set in which the dehumidifier is approved. For each weekday, three times can be specified, fur-
thermore, you can copy individual day to other days. The dehumidifier is shut down outside of the set times.
Solar
This function is used to control a solar pump.
Tmin St.
Enable/start temperature at sensor X:
If this value on the specified sensor is exceeded and the other conditions are not fulfilled, the controller will turn on the affiliated
pump or the valve. If the temperature on the sensor falls 5 °C below this value, the pump or the valve will be turned off again.
Δ T Solar
Switch on/switch off temperature difference for sensor X:
If the temperature difference ΔT Solar between the reference sensors is exceeded and the other conditions are fulfilled, the con-
troller will turn on the pump/valve on the corresponding relay. If the temperature difference falls to ΔT Off, the pump/valve will be
turned off again.
Tmax
Switch off temperature at sensor X:
If this value is exceeded at the specified sensor, the controller turn off the affiliated pump or the valve. If this value on the sensor is
undershot and the other conditions are fulfilled, the controller will turn on the pump or the valve.
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be
provided by the customer!
Starting aid
For some solar systems, in particular for vacuum tube collectors, the measurement recording on the collector sensors may be too
slow or imprecise, because the sensor is often not on the warmest spot. With an activated starting aid, the following procedure
occurs: If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar cir-
culation pump will be turned on for the set “purging time so that the medium to be measured is transported to the collector
sensor. If there is still no normal switching condition through this, there will be a 5 minute block time for the start wizard function.
This function should only be activated by a technician if problems occur with the measurement recording. Observe in
particular the instructions from the collector manufacturer.
The menus "Purging time" and "Increase" are only displayed when the starting aid function is set to "On".
35
Purging time
If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar circulation
pump will be turned on for the set “purging time so that the medium to be measured is transported to the collector sensor. If when
the set ΔT is reached this does not switch on, a 5-minute circulation pause time for the starting aid function will apply.
Increase
If the temperature at the collector reaches within a minute the value defined, the solar pump is turned on for the duration of the
purging time.
Protective functions for Solar
The protection functions for Solar are not displayed in the “Protective functions” menu, but rather as a sub-menu in the
settings from the solar function, see " Solar " on page 35.
System protection
Priority protection function
The system protection should prevent an overheating of the components installed in the system through the forced shut down of
the solar circulation pump. If the value “AS Ton” on the collector has been exceeded for 1 Min. the pump will be turned off and not
turn on again in order to protect the collector, for example, from steam. The pump is turned on again when the value “AS Toff” on
the collector has not been met.
With the system protection (on), there are increased standstill temperatures in the solar collector and therefore an
increased pressure in the system. The operating manuals from the system components must be observed.
Collector protection
Priority protection function
The collector protection prevents the collector from overheating. A forced switching of the pump makes sure that the collector is
cooled through the storage. If the value “KS Ton” is exceeded on the collector, the pump will be turned on in order to cool the col-
lector. The pump is shut down if the value “KS Toff” on the collector is not met or the value “KS Tmax Sp.” on the storage or KS SB
Max on the pool is exceeded.
System protection has priority over collector protection! Even if the switch requirements for the collector protection are
present, the solar circulation pump is turned off once “AS T on is reached. Normally the values from the system pro-
tection (depending on the maximum temperature of the storage or other components) are higher than the collector pro-
tection.
Recooling
In the system hydraulics with solar, excess energy is guided from the storage back to the collector with an activated return cooling
function. This only occurs if the temperature in the storage is greater than the value “Return cooling Tref” and the collector is at
least 20 °C colder than the storage and until the storage temperature has fallen below the value “Return cooling Tref”. For muti-
storage systems, the return cooling applies to all storage.
Energy is lost through the collector through this function! The recooling should only be activated in cases of exception,
with low heat acceptance, for example, during vacation.
Frost Protection
A 2-level frost protection function can be activated. In level 1, the controller turns on the pump every hour for 1 minute if the col-
lector temperature is below the set value “Frost Level 1”. If the collector temperature continues to decrease to the set value “Frost
Level 2”, the controller will turn on the pump without disruption. If the collector temperature exceeds the value “Frost level 2 by 2
°C, the pump will turn off again.
Energy is lost through the collector through this function! It is normally not activated for solar systems with antifreeze.
The operating manuals from the other system components must be observed.
Collector alarm
If this temperature at the collector sensor is exceeded when the solar pump is turned on, a warning or error notification is
triggered. There is a corresponding warning in the display.
Collector
Collector sensor
The collector sensor can be determined or changed here. The collector sensor set here is used for solar function ( Tmin collector,
∆T Solar,....) as well as all protection functions Solar (collector protection, system protection, ...).
Solar storage
The solar storage sensor can be determined or changed here. The solar storage sensor determined here is used for the solar
function ( Tmax storage, ∆T Solar,....).
36
Solar bypass
Use a relay to switch a bypass valve or a bypass pump. With this function, the flow can be guided past the storage if the flow tem-
perature at the bypass sensor is less than in the storage to be filled.
Variant
In this menu, you can set if the flow is guided through the bypass with a pump or a valve.
Bypass sensor
The reference sensor for the bypass function to be placed in the flow is selected in this menu.
Booster
This function can control an additional booster pump for filling a resistance system.
Charge time
When solar charging begins, the connected booster pump fills the system for the time set here.
Zone valve
This feature can control a solar accumulator charging valve. This enables charging of a second tank or second tank zone. The
number on the left next to the zone valve indicates which tank / zone is being charged by the system.
Tmax storage 2
Maximum temperature storage 2. Up to this temperature, store 2 or the 2nd store zone will be charged.
Solar storage 2
In this menu, the storage tank sensor 2 must be set.
Heat exchanger
Adds a heat exchanger and a secondary pump to the solar circuit. Function is only visible if the additional funciton Solar is activ-
ated.
Heat exchanger sensor
The sensor that is used to turn on the secondary pump. It must be on the primary side on the heat exchanger.
Return flow increase
With this function, for example, the return temperature of a heating circuit is increased through the storage.
RF Tmin
Minimum temperature at storage sensor to enable the return flow increase. As soon as this temperature at the set storage sensor
is exceeded and adequate ΔT is present, the relay is turned on.
RL Tmax
Maximum temperature set on the storage sensor set for this function If this temperature is exceeded at the RL storage sensor, the
function is deactivated again.
ΔT return flow
Switch on temperature difference:
The relay is turned on if this temperature difference is exceeded between the storage sensor and the recooling sensor.
37
Switch off temperature difference:
The relay is turned off if this temperature difference is undershot between the storage sensor and the recooling sensor.
Return flow sensor
Selection of the return flow sensor.
Storage sensor
Selection of the storage sensor.
Domestic hot water valve
A domestic hot water valve is switched with time and temperature control with this function.
Circulation
Depending on the temperature and time approval, a circulation pump is turned on for the DHW storage.
Tmin
If this value at the circulation sensor is undershot and the circulation is approved or there is a request through a tapping process,
the circulation pump is started.
Hysteresis
If the circulation Tmin value is exceeded by the value set here, the circulation pump will be shut down.
Circulation sensor
If the circulation Tmin value is exceeded by the value set here, the circulation pump will be shut down.
Circulation pause time
In order to prevent an excessive switching on of the circulation pump, a block time can additionally be set up here to prevent
it from being turned on again. If the circulation pump has turned off, it can first go into operation again after the expiration of the
time set here.
Purging time
If during the operation of the circulation pump, also after expiration of the optional purging time, the previously selected tem-
perature at the circulation sensor is not reached, the pump will turn off. This function should protect against unnecessarily long
operation of the circulation pump, for example, if the warm water storage is too cold.
Circulations periods
Operating times of the circulation
Here the desired periods are set in which the circulation is approved. For each weekday, three times can be specified, fur-
thermore, you can copy individual day to other days. The circulation is shut down outside of the set times.
