Carrier AquaSnap 61AF 075 - Accessory 00 PPG000488200- Heating System Manager Type C

14.3 - Accessory 00PPG000488200- Heating System Manager type C
Heating system control (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
61AF heat pump and two di󰀨erent heat emitter types and/or two
independent comfort zones. For optimised energy e󰀩ciency the
heat pump is controlled by a congurable 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.
Heating system example: with the possibility to obtain additional heating and domestic hot-water
