The ThermoConnect system is designed
for controlling Webasto air - and water
heaters with any compatible mobile phone

network connection. Commands are send
by a mobile phone with the
ThermoConnect app or a web browser
(My WebastoConnect).
For more information, please con-
tact the Webasto Service Centre.

Do not disconnect the plugs from
the cables.
Installation:
■GPS antenna:
-The text 'GPS' is facing up.
-GPS needs a clear view of
the sky.
■GSM antenna:
-Not close or next to metal
surfaces.
-For the best signal reception:
Preferably, install the GSM
antenna (2) as high as possi-
ble. Generally, higher antenna
position means better signal
reception.
 Select an installation area for the an-
tennas, for example, at the bottom
edge of the windshield.
 Clean the installation spot of any dirt,
grease or stains
 Attach / install the antennas with ad-
hesive tape.
 Feed the wires from GPS antenna and
