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 (thermostat or
BT-M6Z02 RF) must be the first paired
device
• Put the device in pairing
mode (refer to device leaflet)
• Follow the instructions given by the
Central (check on the device that
the pairing is successful, refer to the
device leaflet)
• 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
procedure. The led should be green fix
on the repater.
• Check the successful installation
You will have warning in home menu
for RF errors communications. The warn-
ing 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
Within an installation, it may be necessary
to control devices such as pumps, valve
drives or heat / cool producers, as soon
as heating or cooling demand exists on at
least one zone.
With WATTS Vision®, up to 4 such devices
can be switched via the “hydraulic circuit”
function.
Each of these 4 possible circuits can be
controlled via a single radio receiver.
STEP 1:Define which device is assigned
to a hydraulic circuit
With the plan of your installation, define
which devices are on “circuit 1”. Then, using
the Central controller, 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

ENGLISH
EN
12 2019 / 06 Watts | PPLIMW15428C
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 BT HCM02 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:
and go in “H&C”.
There you will have the choice netween
“Heating Only” “Cooling Only” or “Manual
Reversible”. With this last option, you cre-
ate 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.

TYPE 1 In this configuration:
• Pair first the thermostat (master) with the Central before pairing the other devices
(configured as heating devices).
• The actuators regulate on thermostat temperature.
TYPE 2 In this configuration:
• Pair first the thermostat (master - configured as a heating device) with the Central
before pairing the other devices.
• The other devices regulate on thermostat temperature.
