GENERAL INFORMATION
Safety warnings and operating
instructions
• This product should be installed
preferably by a qualified profes-
sional. Subject to observation of the
above terms, the manufacturer shall
assume the liability for the equip-
ment as provided by legal stipulations.
• All instructions in this Installation &
Operation manual should be observed
when working with the controller.
Failures due to improper installation,
improper use or poor maintenance
are voiding manufacturer liability.
• Any attempt to repair voids the respon-
sibility and the obligation to guarantee
and replacement from the manufacturer.
• Do not cover the thermostat. The ther-
mostat opens and closes as deter-
mined by the temperature around it.
Therefore the sensor must never be
hidden behind thick curtains, furni-
ture, etc… Alternatively a thermostat
with remote sensor should be used.
• Batteries may explode or leak, and
cause burn injury, if recharger, disposed
of fire, mixed with a different battery
type , inserted backwards or disas-
sembled. Replace all used batteries
at the same time. Do not carry bat-
teries loose in your pocket or purse.
Do not remove the battery label. Keep
batteries away from children. If swal-
lowed, consult a physician at once.

2. FIRST INSTALLATION
2.1 Thermostatic head installa-
tion on the radiator valve
You need first to select a brass adaptor nut
compatible with your TRV.
The BT-TH02 RF must be installed with
the axis in opened position, so you can
install it directly on the radiator valve before
power on the product (See steps drawings
on the right)
Nota: If the valve is closed, it may block the
operation of installation on the radiator.
In that case, you need to power on the
product (remove the strip of the batteries)
then follow this procedure:
• Go in the Parameters Menu number 10
by pressing and maintain the ( ) key for
more than 5 seconds, and we will see
the following screen:
Axis in opened
position for installation
Axis in closed
position
You can then install the product on the radiator
valve.
Push the ( ) key
to finish (Clos)
• Press the ( ) key to validate. You will
see OPEN. Wait the backlight extinction,
the motor will perform the completely
open move

When the product is powered on, the thermostatic head starts the procedure of stroke
self learning.
Note : For the step 4, if the product is already powered on, you need to close the valve.

** To ease the installation, it will be better to
have the Central Unite near to the thermo-
static head during the configuration mode.
(A minimal distance of > 1 meter must be
respected)

4. IN COMBINATION WITH
CENTRAL UNIT
4.1 Installation
If your thermostatic head works in com-
bination with a RF Central Unit, it will
become a remote unit.
To configure your thermostatic head with
the BT-CT02 RF (Central Unit (1)):
• Press and maintain the ( ) key during 5s,
then you are in the Parameters Menu
number 10. Press the RIGHT key ( ) to
be in the RF pairing mode (User Menu
number 11).
• Now put your Central Unit in RF pairing
mode too. (please refer to the Central
Unit leaflet for this) The Central Unit will
now send the radio configuration signal
(2) to the thermostatic head.
• After few seconds, the Central Unit and
the thermostatic head should exit by
themselves the RF pairing mode, this
is the normal procedure to confirm a
correct pairing.
• Now, you can check the RF distance and
if RF signal is strong enough, replace
the Central Unit to its room. Return
to your room where the thermostatic
head is placed. Put your thermostatic
head in Comfort mode (setting tempera-
ture position 30°C), wait the backlight
extinction and 5 seconds more (RF
antenna will blink during RF communica-
tion on the LCD).
• Now return to the Central Unit to see
the setting passes through the RF and
is also equal to 30°C in the Central Unit.
If the RF signals were received correctly,
adjust your setting temperature as you like.
> 1 m

ENGLISH EN
15
If the RF signals weren’t received correctly,
check the installation (Position, distance...)
or restart the RF pairing rules to be sure.
You may have to use a Watts RF repeater if
you want to extend the RF range.
Please note that this is not possible to
make a direct RF pairing between the
BT-TH02 RF and a BT RF thermostat. If
you want to use a BT RF thermostat in a
room, you should pair the RF thermostat to
the Central Unit BT-CT02 RF, then pair one
or several BT-TH02 RF to the Central Unit.
4.2 Starting
The thermostatic head is now ready to
work with the Central Unit. The default
working mode will be the mode imposed
by the Central Unit.
In case of Automatic mode , no pro-
gram can be changed from the thermostatic
head, the program is directly set inside the
Central Unit (see Central Unit leaflet). The
following screens can be viewed:
Setting View
Clock View
Note: the time will be also sent by the
Central Unit, then all your installation will be
synchronized with the same time.
At any time, when the backlight is off, press
any key to light-up the backlight, and then
press another time the ()key to switch the
view between the setting temperature and
the time values. The days are not shown
anymore as no programmation is available
in the thermostatic head. Programmation is
only possible inside the Central Unit.
4.3 Working modes
With the Central Unit, the Clock update
and program modes are note available
anymore as setting time values and pro-
gram values are directly configured in the
Central Unit.
The following modes are available; refer
to stand-alone version chapters for more
explanations
• Timer / Booster mode
• Manual mode, comfort
• Automatic mode
The thermostatic head will follow the pro-
gram selected on the Central Unit.
• Manual mode, reduced
• Manual mode, Antifreeze
The anti-freeze temperature is set by the
Central Unit (see the leaflet of the Central
Unit to change the anti-freeze value of your
installation)
• OFF mode

5. SPECIAL FUNCTIONS
5.1 Keyboard lock Function
Use this function to prevent all change of your
settings (In a child room, public area…)
• To activate the Key lock function, press
maintained the both LESS ( ) or MORE
( ) keys.
• The logo will be displayed on the screen.
• Repeat the same procedure to unlock the
key board.
5.2 Open window function
Conditions of open window detection:
The thermostatic head detects an “Open
window” if the room temperature decreases
by 5°C or more during a 30 minutes period
(or less).
In this case, the thermostatic head follows
7.0°C setting. The function remains active
until the room temperature increases or until
any key is pressed.
As an indicator of this function running, the
logo will blink.
Return to normal mode:
• Automatically: Room temperature increas-
es again for more than 1°C in less than
½ hour
• Manually: Press the ( ) button
Then the blinking logo should disappear to
indicate the end of the detection and return to
previous setting temperature.
Special cases:
• This function doesn’t work if Thermostatic
head is in OFF / Antifreeze Mode
5.3 Valve exercise function
This function is performed if the thermostatic
head doesn’t move during 2 weeks.
This function doesn’t work in OFF mode.
6. PARAMETERS MENU
Your thermostatic head has parameters menu,
in order to enter in this menu, press and
maintain the () key during 5 seconds. Then
parameters menu will appear and first param-
eter screen will be displayed: Now you can
select a parameter which must be adjusted
with the navigation LEFT ( ) or RIGHT ( )
keys, once the parameter chosen, toggle the
value with the ( ) key, modify it with LESS (
) or MORE ( ) and confirm your adjustment
with ( ) Key.
To leave the parameter menu, choose the

description:
Put a thermometer in the room at 1.5M
distance from the heater and check the
real temperature in the room after 1 hour.
When you enter on the calibration param-

the message no will be displayed.
16 ITCS Intelligent Temperature Control
System
YES | no
This function will activate your installation
in advance (2 hours maximum) to assure
the desired temperature at the hour pro-
grammed following your weekly program.
This automatic control system works in
the following way: When you start your
thermostatic head for the first time, it will
measure the time taken by your heater
to reach the set temperature. The ther-
mostatic head will re-measure this time
at each program change to compensate
external temperature change & influence.
You can now program your thermostatic
head without the need to adjust the
temperature in advance because it does
automatically this for you.
17 Win Open window
YES | no
This function, if activated, will detect the
room temperature decreasing for more
than 5°C and will automatically put the
setting to 7°C to save energy. (see sec-
tion 4.2 for more details)
