Before installation
• Carefully read this technical description
• Check whether the module is compatible with the designated vehicle and make sure that the
required functions are supported by the module.
Module programming
The module is equipped with a micro-USB port which is used for connection of the module to a
PC via a micro-USB cable allowing to carry out programming and adjusting various settings of the
module by means of a special software which is called TECPROG (available for download at www.
tecel.ru/en/ or www.canbus-alarm.com). The software allows to program the module without ad-
ditional devices, quickly update the rmware, set a required vehicle model, activate the auxiliary
heater mode if desired, set up the module operation time, etc. The programming can also be carried
out either with a programming button – one of the vehicle’s interior buttons (the information on
which button is used on a particular vehicle is available at www. tecel.ru/en/ website), or with the
built-in button (gure 3).

Vehicle Identication
Identication is performed via TECPROG software or manually by using the built-in button.
Description of manual identication using of the built-in button:
CAN bus should not be connected prior to implementation of the identication procedure.
1. Power up the module. Wait for LED to star blinking.
2. Press the built-in button 4 times. The LED will flash 4 times (or will indicate programmed
group-subgroup) and will stay lit.
3. Enter a group number by the built-in button. After a short pause (1.5 second) the LED shall
indicate the entered number.
4. If group number consists of 2 digits – enter first digit, wait for indication, then enter second
digit and wait for indication
5. Enter a subgroup number. After a short pause (1.5 second) the LED shall indicate the entered
number. After a pause (about 4 seconds) the LED shall indicate the entered number (group
and subgroup) as a sequence of digits.
6. If a group and subgroup are entered correctly, press the built-in button one time, or two
times, if there was an error.
7. If the input data is correct (such model exists) the LED will blink 4 times and the unit will
reboot.
8. If the input data is wrong, the LED will light up for 15 seconds, expecting new group-subgroup.
If within 15 seconds there was no data entry – module will leave programming mode.
Connection to CAN bus
Connection types
There are two types of module connection to CAN bus:
• Parallel connection. It is used to control factory heaters. CAN1 pair is used for parallel
connection in all vehicles.
• Connection by cutting into CAN-bus. It is used to control factory heaters and the climatic
system.
In case of series connection CAN1 pair is connected from the vehicle’s side, and from the side
of a climatic system, CAN2 or CAN3 depending on vehicle model.
For description of FanControl-U2 module connection in specic vehicles and operational-
features with respect to different vehicles please visit www.tecel.ru/en/ website.
Module control
The module can be controlled:
• By the factory vehicle button (for information on which button is used for a particular
vehicle – see www.tecel.ru/en/ or www.canbus-alarm.com website)
• By the factory remote control
• By additionally installed devices through external input (GSM module, auxiliary car alarm etc.).
Module control by the factory vehicle button
Module activation/deactivation is performed by a long (not less than 2 seconds) pressing of a
certain factory button.
Module control by the vehicle factory remote control
Activation of the module is performed by triple pressing on the locking button not less than 15
seconds after the vehicle alarm is armed.
Deactivation of the module is performed by triple pressing on the unlocking button .
Pause between pressing on the button should be ~ 3 seconds.

1 — Heater operation (status).
The output generates a constant level signal
while a heater is running (If it is activated with
FanControl);
2 — Control of recirculating pump.
The output generates a constant level signal
while the engine heater is running and also
within 2 minutes after the heater is deactivated.
The signal is formed if the heater is activated
with FanControl.
3 — Interior ventilation running (status).
The output generates a constant level while
the ventilation is running (If it is activated with
FanControl).
4 — The ignition imitation.
The output generates a pulse signal during 5
sec. The output stops generating the signal
earlier if the FanControl module detects that
the ignition has been turned OFF or the heater
has shutdown.
5 — Auxiliary air heaters control.
The output generates a constant level signal
if the engine heater is turned ON. The output
stops generating the signal if the engine heater
is turned OFF. The output doesn’t generate any
signal if the auxiliary heater mode is activated.
6 — Cooling system loop-switching valve
control.
The output generates a constant level signal
after the engine heater is turned ON. The output
stops generating the signal in 20 minutes after
the engine heater has been turned off. If the
engine has been started before 20 minutes
expire – the signal will vanish in 5 minutes.
If the engine has been shut down before 5
minutes expire – the module will continue
generating the signal for 20 minutes.

2 — After the ignition is turned ON.
* Used only in special cases. Check documentation to see which vehicles require these settings (www.tecel.ru/en/).
** Sensor is installed if there is no data in the CAN-bus.
Heater operation time
This option (table 3 option №10) allows to setup the module operation time (from 10 to 120
min. with 10 min. intervals). Programming is performed with the programming button (vehicle's
OEM button or the built-in one).
To be able to check or change the value of this option - switch the vehicle's ignition ON, no later
than in 10 seconds after turning the ignition ON press the programming button 10 times, wait
until the module indicates the option status by the corresponding number of LED flashes (from 1
to 12). To change the time interval, enter a desired value by pressing the programming button the
number of times required to advance from the current value to a desired one.

Technical manual of FanControl-U2 module

The default value is 3 (30 minutes). To exit the programming mode turn off the ignition or wait
for 30 seconds after the last press on the programming button was made.
The value of this option is ignored if the module is controlled via the status external control
input №11 (pink/black). The module remains activated until the signal is present at the
input, but for no longer than 120 minutes.
Auxiliary heater mode
In this mode an aftermarket self-contained heater operates according to the algorithms of an
OEM auxiliary engine heater: if the ambient temperature is below 5°С, the module will autmatically
switch into the auxiliary heating mode. If the ambient temperature rises above 12 °C, the heater
will switche off automatically.
To activate/deactivate the auxiliary heating mode switch the vehicle's ignition ON and press the
programming button 12 times (a standard button or the built-in one). The module shall indicate
the option №12 "Auxiliary heater mode" status (refer to the table 3 "System setup") as follows:
• 1 LED flash – the auxiliary heater mode is ON;
• 2 LED flashes – the auxiliary heater mode OFF (the default value).
W‑BUS/Eberspächer protocol selection
In most cases, the protocol is assigned automatically when you connect the system to a heater.
Manual selection of the protocol is required in exceptional cases. Programming is performed only
by the built-in button (see Figure 2). In order to select a protocol switche the ignition on, press the
programming button 6 times. The module shall inform about the item status by series of flashes:
• 1 signal – protocol is not set (factory settings).
• 2 signals – W-BUS.
• 3 signals – Eberspächer
• 4 signals – control is disabled.
Change item status by pressing the programming button as many times as it is required. The
module exits programming mode in 15 seconds after the last button-pressing. Upon successful
saving of settings, the LED would flash 4 times; 1 long flash means an error.
Set heat‑up temperature limit for aftermarket heater
This option is used with some vehicles in exceptional cases. You may nd recommendation
to use it in the corresponding manual (check www.tecel.ru/en/ or www.canbus-alarm for latest
manuals).
To change this option press programming button 15 times. Module will inform about its state
with series of LED flashes:
• 1 flash – off (factory default)
• 2 flashes – 71°C
• 3 flashes – 73°C
• 4 flashes – 75°C
• 5 flashes – 77°C
• 6 flashes – 79°C
• 7 flashes – 81°C
• 8 flashes – 83°C
• 9 flashes – 85°C.
