Function description
The liquid gas heater “Truma Combi” is a warm-air heater with
integrated hot water boiler (10 litres volume). The burner oper-
ates fan-supported, which ensures trouble-free function even
when on the move.
In winter operation the heater can be used to heat the room
and simultaneously warm water. If only warm water is re-
quired, select summer operation.
– In summer operation, the water contents are heated in
the smallest burner stage. Once the water temperature is
reached, the burner switches off.
– In winter operation, the unit automatically selects the
required power setting according to the temperature differ-
ence between the temperature set on the control panel and
the current room temperature. When the boiler is filled, the
water is automatically heated as well. The water temperature
depends on the selected operational mode and the heater
output.
At a temperature of approximately 3 °C at the automatic
FrostControl safety/drain valve, the valve will open and drain
the boiler.
