SIM card
A SIM card not included in the
delivery scope is required to operate
the unit.
Both 1.8 V and 3 V SIM cards of a
network operator, which supports
the GSM 900/1800 mobile
communications standard, can be
used.
Always observe any information of
the respective network operator
when operating the SIM card. No
warranty can be given for the SIM
card used. The function should be
checked separately in individual
cases.
Before inserting the SIM card, the
PIN code must be changed to 1234
with a mobile phone. Information on
this topic is contained in the
respective operating instructions of
the mobile phone.
All data which may be present on
the SIM card will be deleted when
commissioning the GSM module.
The SIM card is inserted under the
sliding cover on the top of the GSM
module with the angled side
opposite the hinge and with the chip
side facing downward.
Only insert or remove the SIM card in
the deenergised state.
The range is dependent on the
respective network operator. Costs
result from the operation of a SIM
card. Information on this topic and
on roaming charges abroad and in
areas close to the border (due to
network overlapping) can be
obtained from the respective
network operator. No liability can be
accepted for any costs arising.

The GSM module must be installed in
the passenger compartment.
-Determine the installation location in
the passenger compartment (under
the instrument panel, when retrofit-
ting preferably near the MultiControl
or the radio receiver)
-Fasten the GSM module with self-tap-
ping screws (ensure sufficient clear-
ance for the connection of the wiring
harness and the antenna)
-Watch vehicle parts located behind
the module when mounting it with
the self-tapping screws! Contacts/
plug connections must face down-
wards.
Installing GSM antenna
The antenna must be installed on
the front or rear window. However,
never in the tinted area or under the
heating wires of the window heater
or wires of the window antenna.
-Clean the window thoroughly with a
cleaning cloth
-Pull the protective film off the anten-
na and glue on the antenna (maintain
a minimum distance of 30 mm from
metal parts)
-Route the antenna cable to the GSM
module (never shorten or kink) and
connect to the module
Installing button with
indicator lamp
-Drill an 8 mm diameter hole in a dum-
my switch or another suitable loca-
tion easily accessible to the driver
(coordinate the installation location
with the vehicle owner if necessary)
-Mount the push button in the 8 mm
dia. hole
-Route the push button wiring harness
to the 12-pin connector on the mod-
ule and connect them (blue wire on
Pin 9, green on Pin 10 and red on Pin
11)
NOTE
Note down the installation
location of the GSM module
on the last page of these
installation instructions, e.g.
for replacing SIM card!

Connection of an alarm
system installed in the vehicle
(Advanced)
The vehicle owner receives a text
message when the alarm system is
triggered.
Insert the wire in Pin 7 of the 12-pin
connector and connect it to the output
of the alarm system (must be a +12 V
signal).
To define which text message
content the ThermoCall TC4 is to use
to inform you, send the following
text message command to the
ThermoCall TC4 following initial
start-up: 1234IBANK:"Entry
command". The entry command
can, for example, be Alarm.
The alarm can be sent to up to 5
phone numbers. To define which
phone numbers are to be used, send
the following text message
command to the ThermoCall
TC4:1234NBANK:XXX:YYY:ZZZ:
VVV:WWW
XXX:YYY:ZZZ:VVV:WWW = phone
numbers to be entered by the user,
e.g.:
[phone]:[phone]
: etc.
Connection of an external
temperature sensor
(Advanced)
This is required for measuring the
temperature outside the ThermoCall
TC4 (e.g. for cargo areas) and for
using the temperature alarm
function.
Required material:
-W bus temperature sensor 9023181A
(not required in combination with
Telestart T100 HTM)
-Y-adapter 9001505A (only required if
acontrol element is connected after
the ThermoCall TC4)
-See the Webasto Accessories Cata-
logue for any required extensions.
Carry out the connection as shown in
the following drawing and illustrations
on the inner cover pages.
To use the temperature alarm, the
phone numbers to be notified must
be reported to the ThermoCall TC4.
To define the phone numbers, the
following text message command
must be sent to the ThermoCall TC4:
1234NBANK:XXX:YYY:ZZZ:VVV:
WWW
XXX:YYY:ZZZ:VVV:WWW = phone
numbers to be entered by the user,
e.g.:
[phone]:[phone]
