Setting Value
External room thermostat for the main
zone:
▪ #: [2.A]
▪ Code: [C-05]
1 ( 1 contact ): When the used
external room thermostat or heat pump
convector can only send a thermo ON/
OFF condition. No separation between
heating or cooling demand.
Benefits
▪ Cooling. Heat pump convectors provide, besides heating capacity, also excellent
cooling capacity.
▪ Efficiency . Underfloor heating has the best performance with the heat pump
system.
▪ Comfort. The combination of the two heat emitter types provides:
- The excellent heating comfort of the underfloor heating
- The excellent cooling comfort of the heat pump convectors
5.2.2 Multiple rooms – One LWT zone
If only one leaving water temperature zone is needed because the design leaving
water temperature of all heat emitters is the same, you do NOT need a mixing
valve station (cost effective).
Example: If the heat pump system is used to heat up one floor where all the rooms
have the same heat emitters.
Underfloor heating or radiators – Thermostatic valves
If you are heating up rooms with underfloor heating or radiators, a very common
way is to control the temperature of the main room by using a thermostat (this can
either be the dedicated Human Comfort Interface (BRC1HHDA) or an external
room thermostat), while the other rooms are controlled by so-called thermostatic
valves, which open or close depending on the room temperature.
