Operating instructions
Always observe the operating instructions and “Impor-
tant operating notes” prior to starting!
The vehicle owner
is responsible for the correct operation of the appliance.
The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the
appliance, to a place in the vehicle where it is clearly visible to
all users (e.g. on the wardrobe door)! Ask Truma to send you
stickers, if necessary.
Before using for the first time, it is essential to flush the
entire water supply system through with clean water. If
the heater is not being used, always drain the water contents
if there is a risk of frost!
There shall be no claims under
guarantee for damage caused by frost!
Materials in the device which come into contact with
water are suitable for use with drinking water (see
manufacturer declaration: www.truma.com – Downloads –
Manufacturer Declaration).

Room thermostat
To measure the room temperature, an external room tem-
perature sensor (i) is located in the vehicle. The location of the
sensor is determined individually by the vehicle manufacturer,
depending on the vehicle type; consult the operating instruc-
tions for your vehicle for further details.
i
i = Room temperature sensor
The thermostat setting on the control panel (1 – 5) must be
determined individually 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 4.
Initial start-up
(or when the fuel tank has run empty)
Filling the fuel lines
The heater normally has to be started up several times to fill
the fuel lines.
Connect unit to control panel to do this. The unit automatically
performs 2 start attempts (initial start and repeat) per switch-
on procedure with a run time of 2 minutes in each case. If no
flame is detected after the repeat start, the unit switches to
fault and has to be switched off and on again at the control
panel.
After a total of 15 unsuccessful starting attempts (initial
and repeat start) without forming a flame, the equipment
is blocked. To remove the block, please contact the Dometic
Service Centre (see Service Booklet or www.truma.com).
Check fuel lines and connections for leaks after filling the
fuel lines.
Taking into operation
Heating operation is basically possible without
restriction with or without water content.
Check to make sure the cowl is unobstructed. Remove any
covers that may be present.
Summer operation
(boiler operation only)
Move the rotary switch on the control panel to position (c –
summer operation) 60 °C. The green (b) and yellow (g) LEDs
light up.
After reaching the set water temperature (60 °C), the burner
will switch off and the yellow LED (g) will be extinguished.
Winter operation
– Heating with water temperature monitoring
Set the rotary switch to the operational setting “e”.
Set the rotary switch (a) to the desired thermostat setting
(1 – 5). The green LED (b) for operation is lit and simulta-
neously indicates the position of the selected room tem-
perature. The yellow LED (g) indicates the water‘s heat-up
phase.
The unit automatically selects the required power level ac-
cording to the temperature difference between the setting
on the control panel and the current room temperature.
Once the room temperature set on the control panel has
been reached, the burner switches back to the lowest stage,
and heats the water content to 60 °C. The yellow LED (g)
will be extinguished after the water temperature is reached.
The warm air fan can continue to run in order to cool the
unit (after-run).
– Heating without water temperature monitoring
Set the rotary switch to the operational setting “d”.
Turn the rotary switch (a) to the desired thermostat setting
(1 – 5). The green LED (b) for operation is lit and simultane-
ously indicates the position of the selected room tempera-
ture. The yellow LED (g – water‘s heat-up phase) will be lit
only when the water temperature is below 5 °C!
