"Heating circuit" function
30
Kelvin the supply line setpoint temperature will be lowered in reduction mode, i.e. outside
the active time windows.
2.3
Switching the heating circuit pumps off and on
Heating circuit pumps are switched off in the following cases:
•
The value set for "Switch-off day" in the operating modes "Automatic" or "Manual day"
for the respective heating circuit is exceeded.
•
The value set for "Switch-off night" in the reduction mode for the respective heating
circuit is exceeded.
•
The value set for "Supply line max limit" plus 5 K control bandwidth is exceeded (only
in the mixed heating circuit).
•
The "HW priority" function is switched on and the "HW reheating" function is active.
Heating circuit pumps are switched on again in the following cases:
•
The outdoor temperature drops below the outdoor temperature set in the respective
operating mode of the heating circuit by more than 1 K.
•
The supply line temperature drops below the set supply line limit temperature by more
than 1 K.
•
The "HW reheating" function is no longer active.
2.4
Hot water
If the temperature at the top of the storage tank lies below the value set for "Start setpoint
value", the reheating by boiler will be switched on.
If the temperature at the top of the storage tank lies above the value set for "Stop setpoint
value", the reheating by boiler will be switched off.
If the "HW priority" function is switched on, the heating circuit pumps will be switched off
and the mixers will be closed during the HW reheating.
You can also switch on the "HW reheating" function by MFC. This MFC switches in parallel
to the "Hot water" function and has no further parameters.
