Deviations of the actual room temperature from the setpoint are acquired and taken into
account when controlling the temperature. Heat gains can thus be considered,
facilitating more accurate room temperature control. The authority of deviation is set as
a percentage figure. The better the reference room (correct room temperature, correct
mounting location, etc.) the higher the value can be set.
• Example:
Approx. 60 %
Good reference room conditions
Approx. 20 %
Unfavorable reference room conditions
To provide the function, following must be considered:
A room sensor must be connected
"Room influence" must be set to a value between 1 and 99 %
There should be no thermostatic radiator valves in the reference room (mounting
location of the room sensor). (If such valves are installed, they must be set to their
fully open position)
The flow temperature is controlled depending on the room temperature setpoint, the
current room temperature and the progression of the room temperature. For example, a
slight increase in room temperature causes an immediate drop of the flow temperature.
To provide the function, following must be considered:
A room sensor must be connected
" Room influence " must be set to 100 %.
There should be no thermostatic radiator valves in the reference room (mounting
location of the room sensor). (If such valves are installed, they must be set to their
fully open position)

In the case of pump heating circuits, a switching differential for temperature control
must be set. The function necessitates a room temperature sensor.
Room temperature limitation does not work in the case of pure weather compensation.
