RECTIfICATIon
Water supply
When the heating system is
switched off, the electrical
safety/drain valve opens.
Outside temperature
below 4°C.
No 12 V power supply at the
drain valve.
Switch the heating on. At
temperatures of about 4°C
and below the drain valve will
open automatically!
Check 12 V supply voltage
and fuses.
The electrical safety/drain valve
will no longer close.
Outside temperature
below 8°C.
No 12 V power supply at the
drain valve.
Switch the heating on.
Without heating operation,
the drain valve will not close
again until temperatures
above 8°C have been reached!
Check 12 V supply voltage
and fuses.
Water dripping from the
electrical safety/drain valve.
Water pressure too high.
Check pump pressure
(max. 2.8 bar).
If connected to a central
water supply (rural or urban
connection), a pressure reducer
must be used, which will
prevent pressures higher than
2.8 bar entering the boiler.
If these measures do not lead to the rectification of the fault, in principle we would ask
you to contact the Truma Service Centre.
