door.Control by the factory remote control:

• Supported.

Control of a factory assistant heaterA label located on the B‑pillar under the driver’s door indicates about presence of a factory

heater.The module allows switching on the factory heater for engine and interior warm‑up from

additional devices (GSM module, auxiliary car alarm etc.) through the external input, by the standardvehicle’s button or by the factory remote control.

Connection of the module in a vehicle with available timer

The module is connected to САN bus at any convenient place, for instance, behind the climate system control unit (Figure 1). Module CAN 1 paired wire is used for connection. For detailed description of connection refer to Diagram 1.

Figure 1

Connection of the module in a vehicle without available timer

The module is connected to the vehicle CAN bus by cutting into it right after the climate system control unit (Figure 2).

Figure 2

When connecting the module to the CAN bus it is recommended to disassemble the relevant vehicle connector and then assemble it again using connector enclosures included in the kit (Figure 3).

Module CAN 1 and CAN 3 paired wires are designed for connection of the module to CAN bus: CAN 3 is connected to the bus from the climate system control unit side, and CAN 1 – from the vehicle’s side.

For detailed description of connection refer to Diagram 2.

Control of an aftermarket heaterThe module allows switching on the vehicle climatic system in that mode which was used before

ignition turn‑off and simultaneously starting an aftermarket heater. The module can be controlled from additional devices (GSM module, auxiliary car alarm etc.) through external input, by the standard vehicle button and by the factory remote control.

Connection of the moduleThe module is connected in the same way as described above: into the vehicle CAN bus right

after the climate system control unit. For detailed description of connection refer to Diagram 3.

If installing heater on Volkswagen Touareg (2011‑‑) with gasoline engine (3.6 L) it is possible for following error to happen: Engine fan switches to maximum speed and “Check‑engine” error is detected. To remove the error service equipment is required.

FanControl allows to solve this issue. While connecting 2 conditions must be met:1 – FanControl should control the heater via bus ( blue/yellow wire).2 – Heater temperature should be limited. It can be done by using TECPROG or with built in

button (refer to Technical description). Temperature should be picked individually for each vehicle.

Module can be set in mode where it’ll switch climate only if coolant has reached 40º. To do so “Alternative algorithm 1” should be activated. It can be done with TECPROG or manually:

1. Within 10 sec upon turning the ignition on press the programming button 14 times.2. The module shall inform about its status with one flash series.3. Press the programming button 1 time.4. The module shall inform about its status with series of two flashes.
