Function description (Combi)

The liquid gas heater Combi is a warm-air heater with inte-
grated hot water boiler (10 litre volume). The burner is fan-
assisted, which ensures that operation is problem-free, even
when on the move.
In heating and hot water mode the heater can be used to
heat the room and heat water up at the same time. If only hot
water is required, select hot water mode.
– In hot water mode, the water is heated at the lowest
burner setting. Once the water temperature has been
reached, the burner switches off.
– In heating and hot water mode, the unit automatically
selects the required operating level according to the tem-
perature difference between the temperature set on the
control panel and the current room temperature. If the
boiler has been filled, the water is automatically heated as
well. The water temperature depends on the selected oper-
ating 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.

Function description (Combi E)

The liquid gas heater Combi E is a warm-air heater with inte-
grated hot water boiler (10 litres volume). The burner is fan-
assisted, which ensures that operation is problem-free, even
when on the move. The unit also has heating elements for
electrical operation.
In heating and hot water mode the heater can be used to
heat the room and heat water up at the same time. If only hot
water is required, select hot water mode.
At a temperature of approximately 3 °C at the automatic
FrostControl safety/drain valve, the valve will open and drain
the boiler.
3 different options are available for operating the unit:
– gas mode only
Propane / Butane for autonomous use
– electrical mode only
230 V for stationary use on camp sites
– or gas and electrical mode – mixed mode
Only possible in winter.
Heating and hot water mode
In heating and hot water mode, the unit automatically
selects the required operating level according to the tempera-
ture difference between the temperature set on the control
panel and the current room temperature. If the boiler has
been filled, the water is automatically heated as well. The
water temperature depends on the selected operating mode
and the heater output.
All 3 energy selection options can be used for winter
deployment.
– In gas mode the unit automatically selects the operating
level that is required.
– In electrical mode output of 900 W (3.9 A) or 1800 W (7.8 A)
can be manually preselected in accordance with the fuse
protection at the camp site.
If more output is required (e.g. heating up or low outside
temperatures) gas or mixed mode should be selected so
that enough heating power is always available.
– In mixed mode 230 V electrical mode is preferred if the
power requirement is low (e.g. for maintaining the room
temperature). The gas burner is not enabled until the power
requirement is higher, and is the first to switch off during
heat-up operations.
Hot water mode
(with filled boiler only)
Gas mode or 230 V electrical mode is used to generate hot
water. The water temperature can be set to 40 °C or 60 °C.
– In gas mode the water is heated at the lowest burner set-
ting. Once the water temperature has been reached, the
burner switches off.
– In electrical mode output of 900 W (3.9 A) or 1800 W (7.8 A)
can be manually selected in accordance with the fuse pro-
tection at the camp site.
Mixed mode is not possible. With this setting the unit
automatically selects electrical mode. The gas burner is
not enabled.
