Truma FrostControl FC JG FrostControl safety drain valve is perfect protection against frost. A non-current safety/drain valve automatically empties the water tank in the event of freezing.
Thanks to this, the drain does not freeze and the water installation is protected.
In the event of overpressure, water is rapidly removed through the drain stub in case of danger such as water freezing in the tank (when the ambient temperature is approximately 3°C).
Only when the ambient temperature reaches a safe range (approx. 7°C) does the safety/drain valve close again. The valve can also be opened manually!
Compatible with Truma devices: electric boilers, B 10/B 14 boiler, B 10/B14 boat boiler.
