Truma FrostControl is a current-free safety and drain valve with a frost guard function. When the temperature at the valve drops below approx. 3°C, it opens by itself and drains the boiler water outside. At overpressure, for example when the boiler heats up, it releases pressure in bursts. It is an accessory for Truma boilers and fixed water tanks and a spare part for the Truma Combi. Version: 10 mm hose connections.

Before you order
The FrostControl is installed in the cold water supply, in a heated space, away from other heat sources. Water drains through the drain socket directly outside, at a splash-protected point. The socket must always be kept clear and the valve should be operated at least twice a year to remove limescale. On a Truma boiler the FrostControl replaces the manual safety and drain valve. Materials in contact with water are drinking water safe. Truma gives no warranty for frost damage. Before ordering, compare the Truma part number with the part in your appliance.
