External Temperature Sensor - Webasto Air Top 3500 Notice De Montage

Hot air system
IMPORTANT
If you use the heater without a hot air inlet hose, the inlet grille supplied
with the heater must be used at all times.
NOTE:
The installation must be checked for:
– Air short circuit between the vehicle's heating system and the heater
air inlet
– Air short circuit between the heater's air inlet and the heater's air
outlet (Figure 7)
– Adequate hot air intake facility (take the air intake from the cool area
of the cabin, for example for installations under a bench)

If you use an installation box the air vent must be sealed in such a way
that no hot air can get into the installation box.

External temperature sensor

We recommend that you install an external temperature sensor if the
heater is installed in an installation box or in places with poor ventilation
(for example under benches). This will prevent the heater having very
short control times.
6.1.1. To install the external temperature sensor
The external temperature sensor must be installed at medium height in
the passenger cabin on vertical surfaces if possible in the area that
requires heating.
The temperature sensor must not
– be in the direct current of hot air (from the vehicle's own heating
system or the hot air heater).
– by close to heat sources (for example the vehicle's own heating
system).
– be placed in direct sunlight (for example on the dashboard).
– be installed behind curtains or the like.
