5 Technical description
The cartronic 1100 W interior heater is equipped with a three-stage switch
(see fig. 3, A, page 4).
The interior heater is operated with a PTC heating element that regulates the
output according to the temperature of the incoming air. As soon as the ve-
hicle interior is warm, the output and therefore also the current consumption
is reduced accordingly (PTC = positive temperature coefficient).
The interior heater is equipped with an automatic overheating fuse. If this
fuse shuts down, the heater must be sent to the factory to be repaired (see
"Troubleshooting" chapter on page 15).

Using the interior heater

➤ Open the bracket on the bottom of the device.
➤ Place the cartronic interior heater at a suitable location in the vehicle inte-
rior (e.g. the front passenger footwell, see fig. 2, page 3).
Caution! Fire hazard!
The interior heater may not be placed on the dashboard or seats.
The device must be aligned in such a way that there is sufficient
free space (see fig. 2, page 3).
Note
To heat up the vehicle interior as quickly as possible, the interior
heater must be positioned as low as possible in the vehicle. The
warm air that comes from the blower should be set in such a way
that it is not directed at the seat or any obstacles. If this happens,
the outgoing warm air is reflected and sucked back into the device
before the car's passenger area can be heated. That results in a
reduced or even completely absent heating effect.
➤ Connect the device to a 230 V AC socket using the connection cable.
