Benefits
▪
Comfort.
-
The smart room thermostat functionality can decrease or increase the desired
leaving water temperature based on the actual room temperature
(modulation).
-
The combination of the two heat emitter systems provides the excellent
heating comfort of the underfloor heating, and the excellent cooling comfort of
the heat pump convectors.
▪
Efficiency.
-
Depending on the demand, the outdoor unit supplies different leaving water
temperature matching the design temperature of the different heat emitters.
-
Underfloor heating has the best performance with the heat pump system.
INFORMATION
Bivalent is only possible in case of 1 leaving water temperature zone with:
▪
room thermostat control, OR
▪
external room thermostat control.
▪
Space heating can be done by:
-
The outdoor unit
-
An auxiliary boiler (field supply) connected to the system
▪
When there is a heating request, the outdoor unit or the auxiliary boiler starts
operating depending on the outdoor temperature (status of the changeover to
external heat source). When the permission is given to the auxiliary boiler, the
space heating by the outdoor unit is turned OFF.
▪
Bivalent operation is only possible if
-
Space heating is turned ON, and
-
DHW tank operation is turned OFF.
▪
Domestic hot water is always produced by the DHW tank connected to the
outdoor unit.
INFORMATION
▪
During heating operation of the heat pump, the heat pump operates to achieve
the desired temperature set via the user interface. When weather-dependent
operation is active, the water temperature is determined automatically
depending on the outdoor temperature.
▪
During heating operation of the auxiliary boiler, the auxiliary boiler operates to
achieve the desired water temperature set via the auxiliary boiler controller.
Setup
▪
Integrate the auxiliary boiler as follows:
