Note!
This modulation mode is not suitable for cascade applications.
Note!
To ensure effective control of the heating circuit pump in line with the nominal
increase, limitation of the boiler temperature differential must be deactivated (set
Temp differential max (2316) to OSV).
Note!
When manual control ends, the pump is switched off briefly during the transition to
pump overrun.
Consequently, the heating circuit pump should only be set to the Temp differential
nominal modulation mode if the overtemperature protection function has been
deactivated for the heating circuit concerned.

Readjustment of the flow temperature setpoint when the pump speed is reduced by
50%. This readjustment is calculated based on the differential of flow temperature
setpoint according to the heating curve and current room temperature setpoint.
