Frost protection valve for installation outside the building, in the system flow and return. The valve must be installed as close as possible to the outdoor unit of the heat pump so that sensitive components of the heat pump are protected from damage caused by freezing of the medium.

If the temperature of the medium in the system drops to 3°C, the thermostatic element inside the valve opens the flow of the medium to the outside, helping to prevent possible damage. If the temperature of the medium rises above 4 °C, the thermostatic element automatically shuts off the water flow from the system. Prior to recommissioning, it is sufficient to check the system pressure, refill heating circuit water, if necessary, and vent the system.
