Information and advice.
FrostControl (safety/drain valve)
Function description
Overpressure safety valve
At an overpressure of around 3.5 bar (e.g. created when heat-
ing up the boiler), the FrostControl opens automatically and
releases the overpressure to the outside intermittently via a
draining connection.
Manual drain valve
The manual drain valve can be opened to drain the water
content.
Frost guard
If there is a risk of frost (at approx. 3 °C ambient temperature),
the FrostControl opens automatically and releases the water in
the boiler to the outside via a draining connection.
The drain valve can only be closed again manually and
the boiler filled again at an ambient temperature of
around 7 °C.
To ensure the system functions correctly, a safety/drain
valve needs to be fitted in the heated room. If this is not
observed, the result may be malfunctions and the drain valve
may open automatically during operation.
