WATER-SOURCE HEAT PUMPS
Accessory 00PPG000488200- Heating System Manager type C
Heating System Manager (as accessory 00PPG000488100-) with the possibility to obtain additional heating and domestic hot-water production capacity from a district heating system: - Allows control of a non-reversible heating system that includes a 61WG heat pump and two different heat emitter types and/or two independent comfort zones. For optimised energy efﬁciency the heat pump is controlled by a conﬁgurable weather compensation system. The control box controls the heating and/or domestic hot-water production support from a district heating system. The control box supplies power to the circulating pumps. Hot-water production can be permanent or programmable with a second setpoint at the heat pump and control of a switching valve.
