Prerequisites for the correct function of room involvement:
•
All control values from the room valves in the heating circuit are available and
connected to the ASM input socket. There must therefore not be any conventional
thermostats in the heating circuit.
•
The heating circuit has been balanced hydraulically.
•
The following parameters for the room involvement function have been optimized. For
this purpose the complete heating system normally needs to be observed and optimized
over several weeks.
Selection of Yes option:
Dependent parameter(s)
Increase supply temperature
Options:
0...10...100 K
This parameter specifies the maximum value up to which the supply setpoint
temperature is allowed to be increased by the "Room involvement" function. This
increase relates to the value specified by the heating curve. A value of 0 K
deactivates the increase by the room involvement.
Decrease supply temperature
Options:
-100...-10...0 K
This parameter specifies the minimum value up to which the supply setpoint
temperature is allowed to be reduced by the "Room involvement" function. This
reduction relates to the value specified by the heating curve. A value of 0 K
deactivates the reduction by the room involvement.
