Description of the EXP settings
18.10.2002
The controller generates the boiler temperature setpoint based on the boost set here
and the current flow temperature setpoint:
The greater the temperature differential between boiler flow and mixing heating circuit,
the quicker the required setpoint can be reached.

5.49 Gain factor of room influence (KORR)
•
The influence of room temperature deviations on the controlled system can be ad-
justed
Defines the influence of room temperature setpoint deviations on the controlled system.
The room influence can be activated and deactivated (operating line 721).

Increase:
Authority of room influence will increase
Decrease:

is divided by 2 and multiplied by the differential (room tem-
perature setpoint minus actual room temperature).
The result is then added to the room temperature setpoint.
