Explaination

Remaining air in the water circuit will be automatically removes

air from the water circuit.

Provides additional heating capacity when the heating

capacity of the heat pump is insufficient due to very low

outdoor temperature. Also protects the external water piping

from freezing.

Balances water system pressure. (Expansion vessel volume: 2L

in 5/7/9kW units and 5L in 12/14/16kW units.)

Four temperature sensors determine the water and refrigerant

temperature at various points in the water circuit.

6.1-T2B; 6.2-T2; 6.3-T1(optional); 6.4-TW_out; 6.5-TW_in

Provides water circuit pressure readout.

Detects water flow rate to protect compressor and water pump

in the event of insufficient water flow.

Circulates water in the water circuit.
Transfer heat from the refrigerant to the water.

Prevents excessive water pressure by opening at 43.5 psi (3 bar)

and discharging water from the water circuit.
