for controlling Webasto air - and water
heaters with any compatible mobile phone
or web app. The ThermoConnect is connected electrically to the air- or water
heater and gets its commands using a 2G
network connection. Commands are send
by a mobile phone with the
ThermoConnect app or a web browser
(My WebastoConnect).
For more information, please contact the Webasto Service Centre.

The Push button includes a temperature sensor. Make sure that the air
can flow around the Push button,
but it must be shielded from direct
air flow from ventilation ducts.
The Push button must be installed.
The Push button has four functions:
1. Switch the heater on/off.

Fig.7 Antenna installation example
1. GPS antenna
2. GSM antenna
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 possible. Generally, higher antenna
position means better signal
reception.
Select an installation area for the antennas, for example, at the bottom
edge of the windshield.
Clean the installation spot of any dirt,
grease or stains
Attach / install the antennas with adhesive tape.
Feed the wires from GPS antenna and
GMS to the ThermoConnect.
Press the plugs on to the
ThermoConnect.
