Room Influence (AMBON):
Owing to the temperature checkback signal received from the room, a constant room temperature is maintained
and, if required, quick setback enabled.
Room temperature deviation is the temperature differential between actual room temperature and room
temperature setpoint.
The setting will activate the room influence on the heating circuit.
Deviations of the actual room temperature from the setpoint are acquired and taken into account by temperature
control.
To be able to use the control variant "Weather compensation with room influence", the following conditions must
be satisfied:
•
An outside sensor must be connected to boiler control
•
Room influence must be enabled to act on the relevant heating circuits
•
There may be no thermostatic radiator valves in the reference room (If such valves are present, they
must be set to their fully open position).
Quick Setback (QSETB):
During quick setback, the heating circuit pump is deactivated.
Function with room sensor:
When using the room sensor, the function keeps the heating switched off until the room temperature has dropped
to the level of the reduced setpoint or the frost level.
When the room temperature has fallen to the reduced level or the frost level, the heating circuit pump will be acti-
vated and the mixing valve will be released.
Function without room sensor:
Quick setback switches the heating off for a certain period of time, depending on the outside temperature and the
building time constant.
Example
Duration of quick setback when Comfort setpoint minus Reduced setpoint = 2 °C
(e.g. Comfort setpoint = 20 °C and Reduced setpoint =18 °C)
