Operating instructions

Read the safety instructions and operating instructions
carefully before starting the appliance. The vehicle owner
is responsible for correct operation of the appliance.
The installer or vehicle owner must affix the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, in a location in the vehicle where it is clearly visible to
all users. Missing stickers can be requested from Truma.

Function description

VarioHeat is a warm air heater for air circulation to heat camp-
ing vehicles quickly. The burner is fan-assisted, which ensures
that operation is problem-free, even when on the move.
The appliance automatically selects the required operating
level according to the temperature difference between the set-
ting on the control panel and the current room temperature.
A boost function for quick heating and a night function for
low-noise operation are also available. The various fan set-
tings allow air circulation mode without heating.
The digital control panel can be used to select other functions
such as time switch or operation of a Truma air conditioning
system. Information on this can be found under Truma CP plus
VarioHeat digital control panel
This appliance always starts up at the lowest setting. If this is
not sufficient to achieve the desired temperature inside the
vehicle, the appliance switches to a higher operating level af-
ter about 5 minutes.

Start-up

– Remove the cowl cover.
– Open the gas cylinder and the quick-acting valve in the gas
supply line.
– Switch on the heater, see.
Truma CP plus VarioHeat digital control panel or
Truma CP classic VarioHeat analogue control panel
If the appliance is not used for a long period, place on the
cowl cover and close the quick-acting valve in the gas supply
line and the gas cylinder.

Room temperature sensor

To measure the room temperature, an external room tempera-
ture sensor is located in the vehicle. The position of the sensor
is determined by the vehicle manufacturer depending on the
vehicle model. More information can be found in the operat-
ing instructions for your vehicle.

The temperature setting on the control panel depends on per-
sonal heating requirements and the design of the vehicle, and
must be determined individually.

Important notes

– If the power supply to the system has been interrupted, the
time / time switch must be reset.

Air conditioning systems – shared use of
IR remote control and Truma CP plus VarioHeat
control panel
– Even after connecting the Truma CP plus VarioHeat control
panel, the IR remote control is available for controlling the
air conditioning system. The Truma CP plus VarioHeat con-
trol panel recognises all settings that are made using the
IR remote control on the air conditioning system. The IR
remote control only transmits the settings that are shown in
its display (no bidirectional communication).
– Only the time switch of the Truma CP plus VarioHeat control
panel may be used to clearly define the start and end time
of a required period.
