Always observe the operating instructions and
‘Important 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 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 claims under
guarantee for damage caused by frost!

Room thermostat
i. Room temperature sensor
To measure the room temperature, an external
room temperature 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 instructions for your
vehicle for further details.
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.
Taking into operation
Heating operation is basically possible without
restriction with or without water content.
Check to make sure the cowl is unobstructed.
Be sure to remove any covers that may
be present.
Turn on gas cylinder and open quick-acting
valve in the gas supply line.
Summer operation (boiler operation only)

position (c – summer operation) 40° C or 60°
C. The green (b) and yellow (g) LEDs light up.
After reaching the set water temperature
(40° C or 60° C), the burner will switch off and
