as thermostats will be placed.
Create all the rooms and re-name them
(e.g. Room 1 = Kitchen, Room 2 =
Lounge, etc)

EN
10 BT-CT03-RF-IOM-FR-W-EN-10-23
3.4 Pair your devices to the
central
• Install your devices (see relevant device
manuals)
• Create the room if it doesn’t exist (See
section 3)
• Go to Radio pairing
• Choose the device type (heating, On/Off
device, etc)
• Choose the room
• Note: The master (WFC-03 HC RF with
thermostat) must be paired first
• Put the device in pairing mode (refer to
the device manual)
• Start the pairing on the Central
• Follow the instructions given by the
Central (check on the device that the
pairing is successful, refer to the device
manual)
• n.b.: Automatic pairing time in case of
RF communication loss: 10s.
• n.b.: Pairing of the repeater: Select any
device type, any room and does not
consider the pairing failure message on
the central unit at the end of the proce-
dure. The led should be green fix on the
repeater.
• When you have finished pairing all devic-
es, please check that the range allows
good communication. To do this, adjust
the setpoint temperature on the central
and make sure that the information is
received by the thermostat/receiver.
• Check the successful installation
In the radio pairing menu, choose test RF
installation.
You will have warning in home
menu for RF errors communications. The
warning flag should appear for a maximum
of 10mn. It would then disappear if there
are no communication problems. If not,
check devices showing RF errors, try
moving them to another place and repeat
the procedure.

4. HYDRAULIC SYSTEM
ASSIGNEMENT
If your installation has several separate
hydraulic circuits containing their own
pumps or boilers, you may want to drive
each pump/boiler separately from specific
heating receivers or thermostatic actua-
tor(s). With Vision® Wireless you can cre-
ate and control up to 4 hydraulic circuits.
Each of the circuits will have an RF remote
circuit receiver linked to it that will activate
the intended pump and boiler. If at least
one heating receiver or thermostatic actu-
ator on the circuit has a demand, the linked
circuit receiver will operate and activate the
pump (and / or boiler).
STEP 1:Definewhichdeviceisassigned
to a hydraulic circuit
With the plan of your installation, define
which devices are on “circuit 1”.
Then, pair and configure all these devices
on circuit 1.
, enter a zone (room) that belong
to circuit 1,
, and select one device of circuit 1
(radio connecting box, radio receiver or radia-
tor thermostatic head)
Now you have entered the
configuration menu of the device. Select
the menu “Heating settings” and make
sure that “Hydraulic heating” is selected
You can now select the
hydraulic circuit linked to this receiver (e.g.
circuit 1).
Repeat the procedure for each device of
the room (zone) you want to link to the
hydraulic circuit. Further devices can be
selected using the buttons or at the
top of the device name.
Repeat the procedure for each room (zone)
that you want to link to hydraulic circuit
1. If you have assigned all rooms / devic-
es, repeat the procedure for any further
hydraulic circuits.
STEP 2:pairing radio receiver hydraulic
circuit with the central unit
For each circuit, you can link a circuit receiver
to drive the pump devices, valve drive or
heat / cool generator of the circuit. This can
be done for example by BT-WR02 RF.
Select “Circuit”, then select the number
of the circuit, e.g. circuit 1. Put the radio
receiver in pairing mode (BT-WR02 RF).
Repeat the procedure for additional
hydraulic circuits.
Heat and Cool installations
If your installation includes both heating and
cooling functions, you can switch either
from Heat to Cool manually or automati-
cally:
• If you have a WFC-03 HCM RF in your
installation set as “Master” (refer to
Manual instruction of the device) then
all is automatic you don’t have to do
anything
• For all other cases, you have to do the
switch manually:
then go in “H&C”.
There you will have the choice between
“Heating Only”, “Cooling Only” or “Manual
Reversible”.

EN
12 BT-CT03-RF-IOM-FR-W-EN-10-23
With this last option, you create a shortcut
in the main menu where you can easily
change Heat/Cool mode
Notes:
• In Cooling Mode, Reduced mode and
Antifreeze mode are inactive:
icon is displayed
instead of or
• In the thermostat, user can configure
the parameter “Cold” that allows the
zone to do Cooling or not. If it is set
to “No”, then if the mode of the zone
is Cooling then the zone won’t make
Cooling.
5. INSTALLATION TYPES (HEATING/COOLING)
TYPE 1 In this configuration:
• Pair first the thermostat (master - configured as a heating device) with the Central
before pairing the other devices (configured as heating devices).
• The thermostatic heads regulate on thermostat temperature.

before pairing the other devices.
• The other devices regulate on thermostat temperature.
Warning! In this installation type, the thermostat (MASTER) must be in regulation Air
mode (not floor or Air + Floor).
TYPE 3 In this configuration (no thermostat):
• BT-TH configured as heating device. BT-PR, BT-FR, BT-WR can be configured as

STEP 3 Create an Account
• Enter your details and select language.
• Select “Validate” (email will be sent to
you with link).
• Go to your email and click on the link.
• Go back to your App account and follow
the on screen instructions.

central unit. The pairing code (valid
24h) is sent to your email inbox.
In the WiFi status menu of the central
unit, enter the pairing code (internet access
password).
Your central unit should appear after a few
minutes in the application or the web page.
Click the refresh button if necessary. WiFi
status should read 2/2.
Please note! It may take up to a few hours
to display all rooms and devices in the
application. You can then operate your
central unit from anywhere.
