Setting
Value
External room thermostat for the
main
zone:
▪
#: [A.2.2.4]
▪
Code: [C-05]
1 (
Thermo ON/OFF
): When the used
external room thermostat or heat pump
convector can only send a thermo ON/
OFF condition.
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
6.2.2 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 user interface 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.
