4.165 Priority of buffer storage tank cooling with
the heat source pump
The priority of the cooling function can be selected (OFF / priority 1 / priority 2).
When the selected priority is released, the heat will be delivered to the boiler by acti-
vating the heat source pump (Q1 and / or Q10). If a mixing valve for maintained boiler
return temperature is used, it will be brought to the through-port position.
This kind of cooling works only if permitted by the selected type of hydraulic circuit.
