Always observe the
operating instructions
and „Important operating
notes“ prior to starting!
The vehicle owner is responsi-
ble for the correct operation of
the appliance.
Before using for the
first time, it is essential
to flush the entire water sup-
ply through with clean warm
water. If the heater is not
being used, always drain the
water contents if there is a
risk of frost! There shall be
no guarantee claims for
damage caused by frost!
Also drain the water prior to
repair or maintenance work
on the vehicle (in the work-
shop!) as the electrical safety/
drain valve opens when the
appliance is switched dead!

Room thermostat
s
s = Room temperature
sensor
To measure the room temper-
ature, an external room tem-
perature sensor (s) is located
in the vehicle. The location of
the sensor is determined indi-
vidually by the vehicle manu-
facturer, depending on the
vehicle type; consult the op-
erating instructions for your
vehicle for further details.
The thermostat setting on
the operating element (1 – 9)
must be determined individu-
ally depending on the heating
requirement and the type of
vehicle. For an average room
temperature of about 23°C,
we recommend a thermostat
setting of about 6 – 8.
Taking into
operation
Before start-up the following
must be checked:
1. Is the cowl free?
Remove all covers, and open
deck cowl if equipment is
being used on boats.
2. Are the gas cylinder and
the quick-action stop valve in
the gas pipe open?
3. Is the fuse protection for
the 230 V power supply at
the camping site adequate for
the selected output (900 W
or 1800 W)?
4. Has the power supply
cable for the caravan been
fully unwound from the cable
reel?
Heating is always
possible in all operat-
ing modes (gas, electric
and mixed operation) with-
out restrictions, with or
without water.
Summer mode
(hot water only)
1. Select required type of
operation at power selector
switch (gas or electrical
operation).
Mixed operation (gas
and electricity) is not
possible in summer mode.
With this setting the unit
automatically selects electric
operation at the preselected
electrical power of 900 W or
1800 W.
2. Set rotary switch to sum-
mer mode (l) 40°C or 60°C at
control unit.
The green „On” indicator
lamp (k) and the yellow water
heating indicator lamp (q)
on the control unit illumi-
nate when the equipment is
switched on. During electrical
operation the yellow indicator
lamp (h) at the power selec-
tor switch also illuminates to
indicate 230 V operation.
When the selected wa-
ter temperature has been
reached (40°C or 60°C) the
equipment switches off and
the yellow control lamp (q)
goes off.
Winter mode
Heating with hot
water requirement
1. Select required type of
operation at power selec-
tor switch (gas, electrical or
mixed operation).
2. Move rotary knob (j) on
the control panel to desired
thermostat setting (1 – 9) for
room temperature.
3. Move rotary switch on the
control panel to „n”.
The green „On” indicator
lamp (k) and the yellow water
heating indicator lamp (q)
on the control panel illumi-
nate when the equipment is
switched on. During electrical
operation the yellow indicator
lamp (h) at the power selec-
tor switch also illuminates to
indicate 230 V operation.
Depending on operating
mode (gas, electrical or
mixed operation) and power
requirement (temperature
difference between selected
and current room tempera-
ture) the unit automatically
selects the necessary power
setting of up to 7800 W.
The unit gradually reduces
the power until the selected
room temperature is reached.
If this temperature has been
reached but the water still
has to be heated, the circula-
tion fan switches off and the
water continues to be heated
to a temperature of 60°C at
the lowest power setting.
The water can be heated
to up to 80°C depending
on the heating power that is
required to achieve the room
temperature.
The yellow indicator lamp (q)
indicates the hot water heat-
ing phase and goes off when
the water temperature is
reached (60°C).
Heating without hot
water requirement
1. Move rotary knob (j) on
the control panel to desired
thermostat setting (1 – 9) for
room temperature.
2. Select required type of
operation at power selec-
tor switch (gas, electrical or
mixed operation).
3. Move rotary switch on the
control panel to „m”.
The green „On” indicator
lamp (k) on the control panel
illuminate when the equip-
ment is switched on. During
electrical operation the yel-
low indicator lamp (h) at the
power selector switch also
illuminates to indicate 230 V
operation.
In this operating position the
yellow indicator lamp (q) only
illuminates at water tempera-
tures of less than 10°C!
Depending on operating
mode (gas, electrical or
mixed operation) and power
requirement (temperature
difference between selected
and current room tempera-
ture) the unit automatically
selects the necessary power
setting of up to 7800 W.
When the selected roomtem-
perature has been reached,
the heater switches off
(independent of the water
temperature).
The water is automati-
cally heated as well if
the boiler has been filled. The
water temperature can reach
up to 80°C depending on the
power and the duration of the
heating.
