1- IQ Room
2- IQ Base
The room thermostats transmit the
setting temperature, the ambient
temperature and the battery status to
the central control unit via radio waves.
Based on this information and a
number of other parameters, the central
control unit will optimise the opening
and closing of the valve of the relevant
circuit in order to achieve the desired
room temperature.
Each room (or zone) can be assigned
1 to 12 channels depending on the remaining availability on the control unit.
Depending on the number of channels available on the central controller, up to
12 room thermostats can be linked to the central controller.
Example: room thermostat 1 = channel 1; room thermostat 2 = channel 2; room
thermostat 3 = channel 3 and channel 4...
The control unit for underoor heating/
cooling is compatible with the transmit-
ters presented above. It regulates the
whole installation in heating or cooling
according to the orders it receives.

3- IQ Home
The mobile application communicates via Bluetooth with the
control unit. It allows you to transmit the setting temperature
room by room, to change the current mode (Comfort, Eco, Frost
protection), to select the cooling or heating mode and to modify
the parameters of the thermostat and the associated channel. It
can also be used to pair a thermostat and be alerted in case of an
unexpected event on one of the thermostats/channels.
Note: The mobile application can be associated with up to 3
control units.
If you want to start a new installation but you already have 3 control
units associated with your mobile application, you must rst delete the
information from at least one of the existing installations in order to start
the new installation.
To do this, go to the settings of your mobile application and click on “Start
a new installation”.

RADIO PAIRING/UNPAIRING
IMPORTANT: Sensitive touch calibration is automatically done after battery
installation or replacement and the front cover has been closed. To do this, put
the front housing back in place, then the thermostat start the calibration, screen
display a countdown. Do not touch the up & down button during the process
until screen turns o󰀨 and back on.
3- Launch the Radio pairing
When this screen appears, release
the buttons. The pairing process
starts (movement of the display).
4- Launch the pairing on the appli-
cation
Go on your mobile application to
launch the radio pairing and follow
the instructions on the screen.
1- Activate thermostat
Short press on the screen with your
hand.
2- Access to Radio pairing
From main screen, press &
simultaneously (> 5 seconds).
The LOC screen will appear, hold
down the and buttons until
the pairing screen appears.
1 sec.
INSTALLING BATTERIES
2- Remove the front housing from the
thermostat.
1- Press on the clip with a nger
or a at screw driver under the
thermostat.
3- Insert the 2 supplied batteries. Note
the correct polarity when inserting the
batteries.
INSTALLATION
Recommended locations for your thermostat.
To ensure that your thermostat provides accurate readings and controls
e󰀨ectively, it must be installed approximately 1.5 m above oor level on an inside
wall, away from direct sunshine and any other sources of heat or cold such as
radiators, cold draughts, etc.
Important: The thermostat measures the temperature of the place where it is
installed. It does not take into account the temperature di󰀨erences that may exist
between di󰀨erent locations in the house if the temperature is not uniform.
• Radio pairing: linking the thermostat to the control unit
and mobile application
1- After installing the batteries, secure
the wall plate with the two screws
provided using the horizontal holes.
The radio room thermostat is xed on the wall with the rear housing of the
product.
MOUNTING OF WALL MOUTING PLATE
2- Replace the front housing of the
thermostat on the wall mounting
plate.
3- Thermostat secures itself by clos-
ing completely the front cover and
hearing "Click".

GENERAL INFORMATION
1- Before setting up your product, please download and launch the mobile
application to follow the instructions.
2- To save a changed value press and simultanously.
3- Two fast ashes means the value is saved.
4- A ashing value means that the value can be changed (a changed value will
automatically be saved within 4 seconds).
• Thermostat identication
If several thermostats are associated with the
control unit, you can easily locate them. To do
this, start identication from the mobile appli-
cation, in the “control unit parameters” section.
Then the corresponding number(s) will be dis-
played on the thermostat(s). In the exemple: i
(identication) 2 = thermostat number 2.
• Radio unpairing
To cancel the radio pairing between the thermostat, the control unit and the mo-
bile application, see the advanced settings page 4, Radio unpairing section.
6- After 4 seconds back to the main
screen. The ambient temperature
appears.
5- Radio pairing complete
YES appears on the display when
the pairing process is complete.

In which cases? If the temperature measured in a room (measured by a reliable
thermometer) is di󰀨erent of at least 1 or 2°C compared to the setting temperature
of the room thermostat.
The calibration adjusts the temperature measured by the ambient temperature
sensor to compensate for a deviation from +5°C to -5°C by increments of 0.1°C.
IMPORTANT: Before carrying out the calibration it is recommended to wait
for 4h after a setting temperature modication to insure that the ambient
temperature is stabilised.

ature.
Display does not appear on thermostat.
- Check batteries.
- Replace the 2 batteries. Only use alkaline AAA (LR3) batteries.
Do not use rechargeable batteries.
The heating does not turn on or o󰀨.
- Your room thermostat may have been set up close to a source of heat or on
a cold wall – put it in a recommended location (see the “Installing” section on
page 2 for these locations).
- Check that the communication works between the thermostat and the control
unit.
The room temperature is not high enough:
- Check the active desired temperature and increase it if needed (see page 3).
The system is not heating but heating demand LED is on:
- If indicator light is on but the system remains cold, then you should contact
your installer.
The thermostat does not regulate properly.
- Check if the device controlled by the room thermostat is connected correctly,
call a qualied installer.
If the problem persists, contact your installer.
