>>> Time factor
B Select how long the compressor should be on or off in heating mode.
Higher set values result in fewer compressor starts and stops, which
achieves higher economy. However, more pronounced temperature
fluctuations in the heating system may result than with lower values.
>> Room sensor
> Room temperature influence
B Set how much a 1 K ( °C) difference in room temperature should
influence the set point value for the flow temperature.
Example: at a 2 K ( °C) deviation from the set room temperature, the
set point value for the flow temperature is changed by 6 K ( °C) (2 K
deviation * factor 3 = 6 K).
The menu is displayed only if a room sensor is installed.
>>> Acknowledge room sensor
B Indicate No only if the room sensor, even if it is installed, should not
be used.
>> Room temperature program
B Choose if the circuit should be controlled with a program or not.
