Installation Diagram:
The heat pump draws free energy from the air and uses it to heat and cool the building,or prepare domestic hot water.
Two heating circuits:
○More flexibility thanks to two zones control
○Independent temperature control of underfloor heating and radiator heating
○User interface shows two different zones temperature
