Remaining air in the water circuit will be automatically removes air from the
water circuit.
Balances water system pressure. (Expansion vessel volume: 8L)
Circulates water in the water circuit.
Prevents excessive water pressure by opening at 3 bar and discharging
water from the water circuit.
Provides water circuit pressure readout.
Detects water flow rate to protect compressor and water pump in the event
of insufficient water flow.
Transfer heat from the refrigerant to the water.
For heating plate heat exchanger
For heating connection pipe of expansion vessel
Four temperature sensors determine the water and refrigerant temperature
at various points in the water circuit. (T2B; T2; Tw out; Tw in)
