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.
Shut-off valve output
Set to follow the thermo demand of the
main zone.
Shut-off valve
If the main zone must be shut off during
cooling mode to prevent condensation
on the floor, set it accordingly.
At the mixing valve station
Set the desired main leaving water
temperature for heating and/or cooling.
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.
6.3 Setting up an auxiliary heat source for space heating
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.
