4.35 Room influence
More accurate room temperature control due to temperature checkback signal from the
space.
Use of heat gains.
Possibility of boost heating and quick setback.
Defines the impact of room temperature deviations on the controlled system.
Room temperature deviation is the temperature differential between the actual room
temperature and the room temperature setpoint.
Setting range Unit Factory setting
0 / 1 Increment 1
The setting will activate or deactivate the effect of room temperature deviations on the
temperature control.
Entry:
0 Room influence inactive: The measured room temperature will not affect
temperature control
1 Room influence active: The measured room temperature will affect the
temperature control
Room influence means:
Deviations of the actual room temperature from the setpoint are acquired and taken into
account by temperature control.
To use the control variant "Weather compensation with room influence", the following
conditions must be satisfied:
• Outside sensor must be connected
• Setting "Room influence" must be active.
• Respective room unit must be connected
• There may be no controlled thermostatic radiator valves in the reference room.
(If such valves are present, they must be set to their fully open position).
