WATER-SOURCE HEAT PUMPS 61WG 020-090
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.
