2. Current room name
3. To create or add a room (zone).
4. To change current room (zone) name.
5. Scroll over rooms.

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 procedure. The led should be green fix on the repeater.

• When you have finished pairing all devices, 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 actuator(s). With Vision® Wireless you can create 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 actuator on the circuit has a demand, the linked circuit receiver will operate and activate the pump (and / or boiler).

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, 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 radiator 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 / devices, 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 automatically:

• 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”.

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:

1. Master-Thermostat
2. Thermostatic heads

• 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.

TYPE 2 In this configuration:

1. Master-Thermostat

• 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.

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):

1. BT-TH
2. BT-PR03
3. BT-FR
4. BT-WR

• BT-TH configured as heating device. BT-PR, BT-FR, BT-WR can be configured as an On / Off or lighting devices.

TYPE 4 In this configuration:

1. WFC-03 HC RF

• Each thermostat is first paired with the appropriate WFC-03 HC RF and then the WFC-03 HC RF are paired with the Central
• During the pairing, the Central automatically creates rooms according to the number of thermostats (rooms) of master controller.

6. SET UP WIFI CONNECTION FOR MOBIL APP REMOTE CONTROL

STEP 1 Connect the central unit to your WiFi network:

• Choose WiFi settings
• Choose Research Networks (searches for your WiFi)
• Choose your WiFi from the list and enter your regular WiFi password
• Observe unit counting down from 120 to zero
• Make sure that the central is now connected to the WiFi network with an IP address (WiFi status should read 1/2)

If after several attempts, connection is unsuccessful, connect the central unit to WiFi manually.

STEP 2 Download the app to your device:

• For PC: click on this link or copy/paste this URL on you Web browser http://smarthome.wattselectronics.com/mobile/dist/#/login
• For Smartphone: download WATTS Vision® application from App store or Google Play.

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.
• Request a pairing code to link your 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.
