Syst pump on heat gen lock
Off
On
This parameter is used to select whether or not the system pump shall be locked when
the heat generation lock is active.
Off
The system pump is also locked when the heat generation lock is active.
On
The system pump is not locked when the heat generation lock is active.
Warning!
Due to the locked system pump in the case of heat generation lock (Syst pump
on heat gen lock (2121) set to Off), frost protection requests from consumers
downstream from the system pump cannot be satisfied while heat generation
lock is active. Also, cold water from these consumers is prevented from
reaching the boiler to ensure it does not trigger frost protection for the boiler.
Also refer to chapter Boiler pump, parameter Boiler pump on heat gen lock (2301)
Note!
Due to the locked system pump resulting from heat generation lock (Syst pump on
heat gen lock (2121) set to Off), the system pump is also locked when a solid fuel
boiler meets the request for heat and Locks other heat sources (4102) is set to On.
In that case, consumers downstream from the system pump do not receive any heat.
