Designation Value range Factory setting Description
MF 4 Hyst 2.0K-10.0K 5.0K Setting the MF 4 hysteresis.
MF 4 Hyst Off 2.0K-10.0K 2.0K Setting the MF 4 hysteresis for the shut-off process.
Max T-supply 80.0°C-180.0°C 110.0°C
Setting the maximum collector temperature.
The collector pumps lock if the corresponding collector
temperature rises above the temperature set here (system
protection).
The pumps are enabled again if the collector temperature
falls below the temperature
[Max T-solar-10K].
Min T-solar on -20.0°C-95.0°C 50.0°C
Setting the minimum collector temperature.
The collector pump is enabled if the corresponding collector
temperature rises above the temperature set here.
Min T-solar off -15.0°C-95.0°C 45.0°C
Setting the minimum locking temperature for the collector
pump.
The collector pump locks if the corresponding collector
temperature falls below the temperature set here.
This function prevents the pump from operating without
relevant heat output.
T-solar protection 80.0°C-180.0°C 110.0°C
Setting the collector protection temperature.
The collector protection function protects the collector
against overheating. If the collector temperature exceeds the
temperature set here and the tank temperature is less than
92°C, the tank will be charged in excess of its maximum
temperature up to 95°C to cool the collector.
The function is interrupted if the collector exceeds its
maximum temperature.
The function is enabled again if the collector temperature
falls below the maximum temperature-3K.

Description
• 31 = Reloading pump storage tank 2.
The F15 function must be at the position 4.
The relay switches if the temperature of the storage tank
rises above the temperature sensor 15 by the amount of the
hysteresis MF hyst.
It shuts off if the temperature falls below the temperature
[F15 + MF hyst Off].
• 32 = direct heating circuit.
Heating circuit with fixed supply temperature (T-MF target).
In the event of a short circuit at the assigned MF-sensor
(over room thermostat/time switch) the heating circuit
pump switches ON and the supply target temperature for
the heat generator is defined.
The pump experiences a lag period after the sensor short
circuit has been corrected.
Description
• 33 = thermostat function.
ON: T-MF > T-MF target.
OFF: T-MF < [T-MF target-MF hyst].
• 34 = bypass valve cooling mode.
The relay switches in the cooling mode
(Separating the conventional heat generator from the cool-
ing circuit and water heating is possible during the cooling
operation). The MF-sensor captures the supply temperature
for the heat generator-regulation.
• 35 = bypass valve cooling mode invers.
The relay is switched in the opposite direction to function 34.
