Function description

Overpressure safety valve
At an overpressure of up to max. 4.5 bar (e.g. created when
heating 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.
