IR receiver and manual on / off
There is an additional pushbutton on the IR receiver (m), with
which the unit can also be switched on and off without the
remote control (e.g. with a ballpoint pen).
If the unit is switched on using this pushbutton, the system is au-
tomatically reset to the factory settings (automatic mode 22 °C).

Device indicating fault. Switch device off, wait for a short time
and switch on again. If red light stays on, contact Truma Service.
Start-up
Before switching on, be sure to check that the camp site
power supply fusing is sufficient (230 V / min. 6 A).
In order to prevent the power cable of the recreational vehi-
cle from overheating (minimum cross-section 3 x 2.5 mm²)
the cable drum must be fully unwound.
The remote control must always be pointed at the infra-red re-
ceiver in order to perform the individual switching commands.
Before switching on for the first time, the remote control must
be tuned to the IR receiver.
Insert batteries (pay attention to polarity)
Setup symbol flashes
(if symbol does not flash, perform Reset)
Point remote control at IR receiver
Press Setup button and hold down
When red LED in IR receiver flashes, release Setup button.
The remote control is tuned to the IR receiver, the Setup sym-
bol goes off and the air conditioning system starts in circu-
lated air mode, at low fan level and with no timer set.
Switching on
Switch on the air conditioning system using the “On/Off
switch” of the remote control. The previous settings are
taken over.
The circulated air fan runs after switching on. The com-
pressor switches itself on after no more than 3 minutes,
and the blue (cooling) / yellow (heating) LED flashes.
Temperature
If necessary, use the “Temperature selection buttons” to
set the required room temperature with “+” and “–”.
Mode
Select the required operating mode by pressing the “MODE”
button one or more times.
Cooling
Heating
Automatic (cooling or heating mode depending on the room
temperature setting)
Circulated air
When the room temperature that was selected using the re-
mote control is reached in cooling mode, the compressor
switches off and the blue LED in the IR receiver goes off. The
circulated air fan continues to run in order to provide ventila-
tion. If the room temperature setting is exceeded, the device
automatically reverts to cooling mode.
When the room temperature that was selected using the re-
mote control is reached in heating mode, the compressor
switches off and the yellow LED in the IR receiver goes off.
The circulated air fan continues to run in order to provide ven-
tilation. If the temperature drops below the room temperature
setting, the device automatically switches to heating mode.
Heating is not possible if the outside temperature is less
than 4 °C. At a temperature of between 4 °C and 7 °C,
the device briefly switches to thawing operation. Heating
mode is unrestrictedly available at temperatures above 7 °C.
In order to ensure that the interior is heated up as ef-
fectively as possible at low temperatures, the air condi-
tioning system operates at the “low” level at room tempera-
tures of less than 12°C. As soon as 12°C is reached, the air
conditioning system automatically switches to the fan level
selected on the remote control.
In automatic mode, cooling / heating mode and the fan
level are selected automatically depending on the room
temperature.
In circulated air mode, the interior air is recirculated and
cleaned by the filters. No LED’s illuminate in the IR receiver.
Fan
Select the required fan level by pressing the “Fan level” but-
ton one or more times.
Fan level (not functional in automatic mode):
low
medium
high
Sleep function
In “sleep function” (cooling mode only) the fan operates at
slow speed and therefore extremely quietly.
Switching off
To switch off, press the “On/Off switch” on the remote con-
trol. The remote control and the device are switched off.
If the air conditioning system is switched on again, the
blue / yellow LED flashes. The circulated air fan runs, and
the compressor switches on after no more than 3 minutes.
Time
Press “Time selection button” and set current time using
the “Time setting” buttons.
