Warning!
Due to the locked boiler pump in the case of heat generation lock (Boiler pump
on heat gen lock (2301) set to Off), frost protection requests from consumers
cannot be satisfied while heat generation lock is active.
Also, cold water from consumers is prevented from reaching the boiler to
ensure it does not trigger frost protection for the boiler.
It is only frost protection for the boiler called for by sensor B2 that can put the
burner and the boiler pump into operation.
Also refer to chapter Boiler pump, parameter Syst pump on heat gen lock (2121).
