Operation while driving

For heating while driving, the UN ECE regula-
tion 122 stipulates a safety shut-off device to
prevent the uncontrolled escape of gas in the
event of an accident. The Truma MonoControl
CS gas pressure regulation system fulfils this
requirement. National regulations and rules
must be followed.
If no safety shut-off device (e.g. no
MonoControl CS) is installed, the gas cylin-
der must be closed while driving and notices
must be attached in accordance with the
valid regulations.

Troubleshooting

If you notice unusual noises or smells,
close off the gas supply and switch off
the appliance.
Danger of fire / explosion if you attempt
to use an appliance that has been dam-
aged by flooding or if the vehicle has been
involved in an accident. A damaged appliance
must be repaired by an expert or be replaced.
Have faults repaired by an expert with-
out delay.
Only carry out repairs yourself if the so-
lution is described in the troubleshooting
guide of this operating instructions.
Following a deflagration (backfire), have
the appliance and the exhaust gas sys-
tem checked by an expert.

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 (if present).
– Open the gas cylinder and the quick-acting valve in the gas
supply line.

If the appliance is not used for a long period, 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.
