Heating circuit
In the heating function, a simple heating circuit in the system controls the time and temperature. The settings of the heating circuit
define "Room Reference (Day)" and "Room Reference (Night)” values for the associated room sensor.
Heating circuit
Activate function.
Room Reference (Day)
The set temperature considered as reference temperature for the defined room sensor in daytime operation. The daytime mode is
defined by the heating circuit periods; three time periods can be specified for each weekday and copied to the following days.
Room Reference (Night)
The set temperature considered as reference temperature for the defined room sensor in nighttime operation.
The nighttime mode is defined outside the heating periods.
Room
This menu determines the sensor for the room temperature.
Periods
Thermostat activity times
Set the desired periods of time when the thermostat should be active. For each weekday, three times can be specified, furthermore,
you can copy individual day to other days. Outside the set times the thermostat is switched off.
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 anti-
freeze, its concentration and the flow from the system and the measured sensor values from the collector and storage are calculated.
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 temperature can be
used for the heat quantity metering, depending on the system, there may be deviations from the displayed collected 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 40°C, read previous temperature 3C, 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 sys-
tem.
Flow temperature sensor (X)
In this menu, it is set which sensor is used to measure the flow temperature.
Return flow sensor
In this menu, you can set which sensor is used to measure the return flow temperature.
Glycol type
In this menu, the antifreeze used is set. If none is used, please set glycol proportion to 0.
Glycol percentage
The percentage of antifreeze in the medium.
Flow rate supply flow (X)
Nominal system flow.
The flow of the system in liters per minute, which is used as calculation basis for heat metering.
Offset T
Correction factor for the temperature difference for heat metering
Since the collector temperature and the storage temperature can be used for the heat quantity metering, depending on the system,
there may be deviations from the displayed collected temperature to the actual previous temperature or the displayed storage tem-
perature to the actual return temperature. This deviation can be corrected with the adjustment value Offset ΔT
Example: displayed collector temperature 40°C, read previous temperature 3C, displayed storage temperature 30°C, read return
temperature 31° means a setting of -20% (displayed ∆T 10K, actual ∆T 8K => -20% correction value)
