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.
