This is how the frost guard helps you in winter.
When the temperature drops well below freezing in winter, it is particularly important to pay attention to various things in the motorhome.
Many are already planning their next winter camping trip.
To make sure you are well prepared, in addition to our “Winter camping” checklist, this report also contains a valuable tip regarding the frost guard.
What is the frost guard?
To prevent the water in the boiler from freezing at low temperatures, a magnetic valve opens a drain at an ambient temperature of no more than 3 degrees. This drains the water before it can freeze.
The Truma Frostcontrol safety valve also protects the water system against overpressure. If the pressure in the water system exceeds 3.5 bar, the valve discharges water intermittently via a drain connection.
The frost monitor (if installed) is always located by the drain tap.
If you want to empty the water system, you don’t have to empty the contents completely into the waste water tank via the taps. The upper rotary switch is used to open the drain valve manually. If the rotary switch is in line with the safety valve, the drain valve is open. If the rotary switch is at right angles to the Frost Control, the valve is closed and the water remains in your water system.
In our video, we briefly and concisely explain how the frost monitor works.
