6.2.2 Multiple rooms – One LWT zone
Underfloor heating or radiators – Thermostatic valves
EBLA09~16D + EDLA09~16D
Daikin Altherma 3 M
4P620241-1B – 2022.05
Setting
Number of water temperature zones:
▪
#: [4.4]
▪
Code: [7-02]
External room thermostat for the main
zone:
▪
#: [2.A]
▪
Code: [C-05]
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
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.
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.
