Operation of the heater
The heater can be started via the timer or Telestart unit, depending on its configuration.
Before switching on the heater, the vehicle heating must be set to "warm". The heater
fan in the vehicle should be set to the 1st speed in the case of a 3-speed fan and to the
2nd speed in the case of a 4-speed fan. Fans with infinitely variable speed should be set
to at least 1/3 of the fan performance.
NOTE:
We recommend that the heating time be set in accordance with the driving time.
Heating time = driving time
Example: For a journey lasting approx. 20 minutes (one way), the duty period
should not exceed 20 minutes.
!
nnbe operated with the fuel specified on the rating plate and
at the nominal voltage specified on the rating plate.
be taken out of operation by removing the fuse if smoke
develops, if unusual burning noises are heard or if there
is a smell of fuel. The heater must not be restarted until
the unit has been checked by personnel duly trained by
Webasto.
be operated for 10 minutes at least once per month, with
the engine cold and the fan set to the minimum setting.
The heater must be inspected by a specialist at the
beginning of the heating season or earlier.
n
n Non-compliance with the installation instructions and the
warnings contained therein will lead to the exclusion of all
liability by Webasto. The same also applies if repairs are
not undertaken by professionals or without using genuine
spare parts. This invalidates the type approval for the
heater and its homologation / EC type permit.

Default setting: Heating mode, 30 minutes.
If the optional summer / winter switch has been installed for the heater, it must be set in
accordance with the time of year. In this case, the heater will heat the interior of the
vehicle when set to the winter position and merely operate the vehicle fan to
ventilate the interior of the vehicle when set to the summer position .
The Webasto heaters – Thermo Top, Thermo Top T, Thermo Top C and Thermo Top E –
as well as the vehicle fan can be switched on and off under remote control from a
distance of up to 600 metres with the Webasto Telestart T70/T80.
A mode change must be made on the transmitter in order to switch on the vehicle fan
(ventilation of the vehicle).
The duty period after switching on via the transmitter is limited by the receiver. The
maximum range can be reached in open country. A shorter range must be expected in
built-up areas.
