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.
