Setting Value
In case of heat pump convectors:
External room thermostat for the
additional zone:
▪ #: [3.A]
▪ Code: [C-06]
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.
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 indoor 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.

5.3.2 Selecting the volume and desired temperature for the DHW tank
People experience water as hot when its temperature is 40°C. Therefore, the DHW
consumption is always expressed as equivalent hot water volume at 40°C.
However, you can set the DHW tank temperature at a higher temperature
(example: 53°C), which is then mixed with cold water (example: 15°C).
Selecting the volume and desired temperature for the DHW tank consists of:
1 Determining the DHW consumption (equivalent hot water volume at 40°C).
2 Determining the volume and desired temperature for the DHW tank.
