Key features:

• The automation ensures stepless power control of the compressor, fan and circulation pump.
• The standard control system regulates the operation of the heat pump and the heating circuits for central heating and domestic hot water.
• The heat pump can be operated in cooling mode. However, it is recommended to use this mode in a system with underfloor heating.

• The device is equipped with automatic defrosting using hot gas (by reversing the cycle).

• The device features integrated temperature and pressure protection for the refrigerant circuit.

• By controlling the heat pump components, the control system aims to keep the parameters of the refrigeration system within the permissible operating range during operation.

• Active frost protection of the water circuit even during cooling operation (electrical supply required)

• Passive frost protection for the water circuit, without electrical supply (if the water circuit is equipped with a thermostatic frost protection valve)

• Option to operate the heat pump via the weather control function

• Fan with energy-efficient electronically commutated brushless motor (EC)

• Flow water temperature up to 67°C

• Hydrophile coated evaporator

• The heat pump can be operated in a radiant heating and radiator system.

• High efficiency in every installation thanks to the Mitsubishi scroll compressor
  Compact, weatherproof design

• Energy efficiency class A+++, temperate climate, applications at low temperatures (EN 14825)

• The user-friendly Carel control system ensures optimal control and correct operation of the system. Remote control is possible using a special internet module.
