C.2 Electrical connection
Danger
Before working on the unit, switch off the power supply and secure it
against being switched on again! Check for the absence of power!
Electrical connections may only be made by a specialist and in compli-
ance with the applicable regulations.
Do not use the controller if the housing shows visible damage.
Caution
Low-voltage cables such as temperature sensor cables must be routed
separately from mains voltage cables. Feed temperature sensor cables
only into the left-hand side of the unit, and mains voltage cables only
into the right-hand side.
Caution
The customer must provide an all-pole disconnecting device, e.g. a
heating emergency switch.
Caution
The cables being connected to the unit must not be stripped by more
than 55mm, and the cable jacket must reach into the housing just to the
other side of the strain relief.
Relay R1 is only suitable for standard pumps (20-120VA) which are
speed-controlled viathe controller. The internal wiring of the controller
is such that residual currents ow over relay R1 even in the rest condi-
tion. Therefore under no circumstances may valves, contactors or other
consumers with low power consumption be operated on this output.
Caution
10
1.Select necessary program/hydraulics
(Fig. B5 resp. D.1 - D.16)
2.Open controller as described under C.1.
3.Strip cables by 55mmmax., insert, t the
strain relief devices, strip the last 8-9mm
of the wires (Fig. C.2.1)
4.Open the terminals using a suitable
screwdriver (Fig. C.2.1) and make electri-
cal connections on the controller (s. D.1
- D.16)
5.Re t upper part of housing and fasten
with screw.
6.Switch on mains voltage and place con-
troller in operation.
C.2.1
Installation
C.3 Installing the temperature sensors
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
The controller operates with Pt1000 temperature sensors which are accurate to the
degree, thus ensuring optimal control of system functions.
If desired the sensor cables can be extended to a maximum of 30m using a ca-
ble with a cross-section of at least 0.75mm². Make sure that there is no contact
resistance!
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or at-mounted sensor suitable for the spe-
ci c area of application with the appropriate permissible temperature range.

6.14 Priority-Sensor
Charging priority in Multi storage systems
A setting must be made as to which storage tank (storage tank sensor) has priority for
charging. Charging of the lower-priority storage tank is interrupted at regular intervals
to check whether the temperature increase at the collector can enable charging of the
higher-priority storage tank.
Setting range: S2 or S3/default setting: S2
6.15 T priority
Temperature threshold for absolute priority
In systems with multiple storage tanks charging of the lower-priority storage tank will
never take place until this temperature at sensor of the highest priority storage tank is
exceeded.
Setting range: from 0°C to 90°C/default setting: 40°C
6.17 Increase
Extension of the charging pause due to temperature increase in the collector
For precise setting of the charging priorities for systems with multiple storage tanks,
the necessary temperature increase of the collector at which the interruption of the
charging into the lower-priority storage tank is extended by one minute is set here. The
interruption is extended because the temperature increase of the collector is expected
to enable charging in the higher-priority storage tank soon.
As soon as T conditions are met, the priority storage tank is charged. If the rise in
temperature falls below the set value, then the charging of the lower-priority storage
tank is enabled again.
Setting range: from 1°C to 10°C/default setting: 3°C
6.16 Loading time
Interruption of charging into the lower priority storage tank
The charging of the lower-priority storage tank is interrupted after the settable time
in order to check whether the collector has reached a temperature level that allows
charging in the higher-priority storage tank. If so, the priority storage tank is charged.
If not, the increase is measured (see 6.17), to check if charging of the priority storage
tank will be possible shortly.
Setting range: from 1 to 90 minutes/default setting: 10 minutes

Menu “7. Protective functions” can be
used to activate and set various protective
functions.
The menu is closed by pressing “esc” or
selecting “Exit settings”.
Caution
This function causes energy to be lost via the collector! It is normally not
activated for solar systems with antifreeze.
Observe the operating instructions for the other system components!
Protective functions
7. Protective functions
If the seizing protection is activated, then the controller switches the relay in question and the
connected consumer on every day at 12:00 or weekly on every Sunday at 12:00 for 5 seconds in
order to prevent the pump and/or the valve from sticking after an extended stationary period.
Setting range R1: daily, weekly, off/default setting: Off
Setting range R2: daily, weekly, off/default setting: Off
A two-stage frost protection function can be activated. In stage 1 the controller switch-
es the pump on for 1 minute every hour if the collector temperature drops below the
set value “Frost stage 1.
If the collector temperature drops further to the set value “Frost stage 2” the controller
switches the pump on continuously.
If the collector temperature then exceeds the value “Frost stage 2” by 2°C, then the
pump switches off again.
Frost protection setting range: on, off/default setting: off
Frost stage 1 setting range: from -25°C to 10°C or off/default setting: 7°C
Frost stage 2 setting range: from -25°C to 8°C/default setting: 5°C
7.1 Seizing protection
7.2 Frost protection
Caution
This does not under any circum-
stances replace the safety facili-
ties to be provided by the cus-
tomer!
43
Protective functions
7.3 System protection
priority protection
System protection prevents overheating of system components by automatic shutdown
of the solar pump. If “SProt Ton” is exceeded at the collector, the pump is switched off.
The pump is activated again when the temperature drops below “SProt TOff.
Automatic shutdown - settings range: On / Off / Default: on
SProt Ton - settings range: 60 °C to 150 °C / Default: 120 °C
SProt Toff - settings range: 50 °C to Ton minus 5 °C / Default: 115 °C
Caution
When system protection is on, the temperature in the idle collector will
be very high, thus the pressure in the system will rise and can damage
your system.Pay close attention to the instructions of the system manu-
facturer.
7.4 Collector protection
Collector protection prevents overheating of the collector. The pump is switched on to
transfer heat from the collector to the storage tank.
If “CP Ton” is exceeded at the collector sensor, the pump is switched on until the tem-
perature reaches “CP Toff” or the temperature “CP Tmax storage” is exceeded in the
storage or pool.
Collector protection settings range: on / off / Default: off
CP Ton settings range: 60°C to 15C / Default: 11C
CP Toff settings range: 50°C to Ton minus 5°C / Default: 100°C
CP Tmax storagesettings range: 0°C to 140°C / Default: 90°C
Danger
When collector protection is active, the storage with the lowest priority
(see 6.14) is heated beyond Tmax (see 6.4, 6.5 and 6.6), which can lead
to scalding and system damage. If no priority storage is selected (Prior-
ity OFF), the storage with the lowest temperature is charged. Charging
of the pool is not possible for safety reasons.
44
Protective functions
In hydraulic systems with solar when the recooling function is activated excess energy
from the storage tank is fed back into the collector. This only takes place if the temper-
ature in the storage tank is higher than the value “Recool Tsetpoint” and the collector
is at least 20°C cooler than the storage tank and before the storage tank temperature
has dropped below the value “Recool Tsetpoint. In systems with multiple storage
tanks the priority tanks is always cooled rst. If “Priority” is deactivated, (see 6.14), the
storage with the highest temperature is cooled rst.
Recooling setting range: on, off/default setting: off
Recooling Tsetpoint setting range: from 0°C to 99°C/default setting: 70°C
7.6 Recooling
Caution
This function causes energy to be lost via the collector! Recooling
should not be activated by default.
7.5 Collector-Alarm
If this temperature is exceeded at the collector sensor when the solar pump is on a
warning or error message is triggered. A warning message is shown in the display.
Collector alarm settings range: on / off / Default: off
Col. alarm - setting range: 60 °C to 300 °C / Default: 150 °C
With the AL-function activated, the TDC 5 makes it possible to heat the storage in
selectable periods of time to “AL Tset, if the energy source is capable of providing suf-
cient heat.
Sensor 6 has to be connected and is used as additional Switch-off sensor. It has to be
placed at a applicable position in the lower area of the storage or the pipe system.
Switch-on and switch-off hysteresis for the heating is +/- 1°C and applies to the coldest
sensor.
AL residence time” is only succesfully completed when all necessary sensors have a
temperature of ALTset +/-5°C for the set time (storage where sensor 2 is installed).
AL function settings range : On or Off/ Default: Off
AL Tset - settings range: 60°C to 99°C / Default: 70°C
AL residence time: 1 to 120 minutes / Default: 60 min
AL heat: Shows the time of the last successful AL heat up
AL periods- settings range : 00:00 to 23:59 Uhr / Default: 03:00 to 05:00
7.7 Antilegionella

This table shows the sensors used by the AL function in every speci c variant. All sen-
sors shown must reacht “ALTset +/-5°C” for the time span “AL residence
AL Sensors
Protective functions
Caution
The anti-Legionella function is switched off at delivery.
This function is only relevant for storage tanks where sensor 2 is
installed. Whenever heating-up has been carried out with the anti-
Legionella function switched on, an information message with the date
appears on the display.
During the anti-Legionella function the storage tank is heated up over
the set value “Tmax S2, which can lead to scalding and damage to the
system.
Danger
This anti-Legionella function does not provide complete protection
against Legionella, because the controller is dependent on suf cient
energy being fed in, and it is not possible to monitor the temperatures in
the entire range of the storage tanks and the connected piping system.
To provide complete protection against Legionella bacteria, it must be
ensured that the temperature is raised to the necessary temperature,
and at the same time there must be water circulation in the storage tank
and piping system by means of other additional energy sources and
control units.
Caution
In the variants 1, 2, 3, 4, 5, 6 AL heating is done via thermostat. In the
other variants suf cient energy has to be provided by the solar collector.

Special functions
Starting the commissioning help guides you in the correct order through the basic set-
tings necessary for commissioning, and provides brief descriptions of each parameter
in the display.
Pressing the “esc” key takes you back to the previous value so you can look at the se-
lected setting again or adjust it if desired. Pressing the “esc” more than once takes you
back to the selection mode, thus cancelling the commissioning help. (see also E.2).
8.3 Commissioning
Caution
May only be started by a specialist during commissioning! Observe the
explanations for the the individual parameters in these instructions, and
check whether further settings are necessary for your application.
All of the settings that have been made can be reset, thus returning the controller to its delivery
state.
8.4 Factory settings
This menu can only be selected and used if additional options or expansions have
been built into the controller.
The associated supplementary installation, mounting and operation instructions are
then included with the speci c expansion.
8.5 Expansions
Caution
The entire parametrisation, analyses, etc. of the controller will be lost
irrevocably. The controller must then be commissioned once again.
48
Special functions
A simple heat metering function for basic system control can be activated in this menu.
Additional settings regarding the glycol, the percentage of gylcol and the ow rate of
the system are required. A correction value for the heat metering is also possible by
adjusting the “Offset ΔT”.
Since the calculation of the heat metering is based on the temperature of the collec-
tor and storage where measuring takes place, a possible deviation from the ow and
return temperature can be compensated with this value. Example: Displayed collector
temp. 40° C, measured ow temp. 39° C, displayed storage temp. 30° C, measured
return temp. 31° C means a setting of -20% (Displayed ΔT 10K, actual ΔT 8K => -20%
correction value)
Heat metering: Settings range: On/off /default setting: Off
AF type- Settings range: Ethylene/Propylene /default setting: Ethylene
Glycol portion -Settings range: 0-60% /default setting: 40%

8.6 Heat quantity
Caution
Keep in mind that the system is not changed, adjustments made in this
menu are only used to calculate the heat volume and should be based
on the actual system. Resulting data is only approximate value for func-
tion control!
With some solar systems, especially with vacuum tube collectors, it may
occur that the measurement value acquisition at the collector sensor occurs too slowly
or too inaccurately because the sensor is often not at the hottest location. When the
start help is activated the following sequence is carried out:
If the temperature at the collector sensor increases by the value speci ed under
Increase” within one minute, then the solar pump is switched on for the set “Purg-
ing time” so that the medium to be measured can be moved to the collector sensor. If
this still does not result in a normal switch-on condition, then the start help function is
subject to a 5-minute lockout time.
Start help setting range: on, off/default setting: off
Purging time setting range: 2 ... 30 sec./default setting: 5 sec.
Increase setting range: 1°C....10°C/default setting: 3°C/min
8.7 Start aid function
Caution
This function should only be activated by a specialist if problems arise
with acquisition of measurement values. In particular follow the instruc-
tions from the collector manufacturer.
50
Special functions
During this time the pump starts up at its full speed (100%) to ensure reliable starting.
Only after this purging time does the pump run with speed control and switches to the
max. or min. speed, depending on the variant set.
Setting range: from 5 to 600 seconds/default setting: 8 seconds
The control time is used to determine the delay for speed control in order to avoid
large temperature oscillations as much as possible. The time span required for a com-
plete control process from minimum speed to maximum speed is entered here.
Setting range: from 1 to 15 minutes/default setting: 4 minutes
The maximum speed of the pump at relay R1 is speci ed here. During the setting the
pump runs at the speci ed speed and the ow rate can be determined.
Setting range: from 70 to 100%/default setting: 100%
The minimum speed of the pump at relay R1 is speci ed here. During the setting the
pump runs at the speci ed speed and the ow rate can be determined.
Setting range: from 30 to max. speed -5%/default setting: 50%
This value is the control setpoint for variant 3. If the value at the collector sensor drops
below this, the speed is reduced. If it rises above this, the speed is increased.

If the controller detects a malfunction, the
red light ashes and the warning symbol
also appears in the display. If the error
is no longer present, the warning symbol
changes to an info symbol and the red
light no longer ashes.
To obtain more detailed information on the
error, press the key under the warning or
info symbol.
Possible error messages: Notes for the specialist:
Sensor x defective ----------------> Means that either the sensor, the sensor input
at the controller or the connecting cable is/was
defective.
(Resistance table see B.1)
Collector alarm --------------------> Means that the collector has fallen/fell below the
temperature set under menu 6.5
Night circulation -------------------> Means that the solar pump is/was in operation
between 23:00 and 04:00. (Exception see 6.6)
Restart ------------------------------> Means that the controller was restarted, for exam-
ple due to a power failure. Check the date&time!
Time&date -------------------------> This message appears automatically after a
mains failure because the time&date have to be
checked, and reset if necessary.
Danger
Do not try to deal with this
yourself.
Consult a specialist in the
event of an error!
54
If the mains voltage is switched on and
the controller still does not function or
display anything, then the internal device
fuse may be defective. In that case, open
the device as described under C, remove
the old fuse and check it.
Exchange the defective fuse for a new
one, locate the external source of the er-
ror (e.g. pump) and exchange it.
Then rst recommission the controller and
check the function of the switch outputs in
manual mode as described under 5.2.

Danger
Repairs and maintenance may only be performed by a specialist. Before
working on the unit, switch off the power supply and secure it against

Only use the supplied spare fuse or a fuse of the same design with the
following speci cations: T2A 250V
Z.2 Replacing the fuse
Z.2.1
Z.3 Maintenance
Caution
In the course of the general annual maintenance of your heating system
you should also have the functions of the controller checked by a spe-
cialist and have the settings optimised if necessary.
Performing maintenance:
- Check the date and time (see 7.2)
- Assess/check plausibility of analyses (see 2.4)
- Check the error memory (see 2.5)
- Verify/check plausibility of the current measurement values (see 1.)
- Check the switch outputs/consumers in manual mode (see 5.2)
- Poss. optimise the parameter settings
55
Instead of setting the ow rate for the system using a ow rate limiter,
it is better to adjust the ow rate using the switch on the pump and by
means of the “max. speed” setting on the controller (see 7.9.4). This
saves electricity!
The service values (see 9.) include not only current measurement val-
ues and operating states, but also all of the settings for the controller.
Write the service values down just once after commissioning has been
successfully completed.
In the event of uncertainty as to the control response or malfunctions
the service values are a proven and successful method for remote diag-
nosis. Write the service values down (see 9.) at the time that the sus-
pected malfunction occurs. Send the service value table by fax or e-mail
with a brief description of the error to the specialist or manufacturer.
In program 13 “Solar with storage tank and pool” the charging of the
pool, e.g. for winter operation, can be switched off using a simple func-
tion. To do this, simply press and hold the “esc” key down for several
seconds on the diagram/overview screen. A message appears on the
display as soon as the pool is switched off or when the pool is switched
on again.
The Operating hours displayed in the “Analysis” menu are solar oper-
ating hours. This therefore only takes into account hours in which the
solar pump is active.
To protect against loss of data, record any analyses and data that are
particularly important to you (see 2.) at regular intervals.
