WATTS BT-WR02 H&C RF Wireless Wall Receiver
Product Information
The BT-WR02 H&C RF receiver is a wall-mounted receiver designed for controlling hydraulic heating regulation or cooling regulation. It features a proportional regulation with a time cycle of 10 minutes and hysteresis regulation. The heating relay can be used to control a boiler, valve, or electric radiator, while the cooling relay is used to manage an actuator for a cold water circuit. The receiver is compatible with thermostats from the BT- XX02 RF or BT-XX03 RF range, except for BT-A02 RF thermostats.
The receiver is delivered with 2 outputs in free contact mode.
To trigger the outputs in live contact, connect the live wire to 1 point of
each connector using the cable supplied in the box.
Product Usage Instructions
- Make sure the power supply is connected to the receiver.
- Configure the thermostat’s address according to the thermostat leaflet.
- Refer to the thermostat leaflet to enter the thermostat in RF pairing mode.
- Ensure that the receiver’s RF LED is switched off and the thermostat exits the RF init mode to indicate correct pairing between the receiver and thermostat.
Presentation
The BT-WR02 H&C RF receiver is a Wall mounting receiver, specially designed to
control hydraulic heating regulation or cooling regulation.
It embeds a proportional regulation with a time cycle of 10mn and a Hysteresis
regulation:
- The heating relay is used to control a boiler in free contact or a valve or an electric radiator in live contact. (Available with all thermostats of the BT-XX02 RF or BT-XX03 RF range).
- The cooling relay is used to manage an actuator for a cold water circuit. (Not available with BTA02 RF thermostats).
This couple (thermostat BT-XX02 or BT-XX03 and receiver BT-WR02 H&C RF) can
also be managed by a Central unit BT-CT02 RF to have a full control of your
heating installation from one point. In that case, the receiver works always
in automatic regulation mode for the heating/cooling switch. With the central
unit, it is possible to pair the receiver in “Regulation/heating” mode and in
“Hydraulic circuit” mode. It is not possible to pair the receiver in lighting
mode or ON/OFF mode.
You can access to the general leaflet of the system on wattswater.eu.
With a BT-D02 RF/BT-D03 RF or BT-DP02 RF/BT-DP03 RF it is possible to
configure the receiver in manual mode, heating mode, cooling mode or automatic
mode (Please refer to the BT-XX02 RF or BT-XX03 RF leaflets).
In all cases, the receiver is making cooling only in comfort mode. All other
modes (Reduced, anti-freeze, auto in Reduced) forbid the cooling regulation.
In case of set point modification, a delay of 5mn is always applied before
switching from cooling to heating or heating to cooling.
In automatic regulation, a dead band of ± 1°K with timer is applied before
switching from heating to cooling or from cooling to heating.

Installation and RF pairing rules
Install and plug the receiver into the following guidelines to guaranty an optimal reception:
- The receiver must be put at a minimum distance of 50cm of all others electrical or wireless materials like GSM, Wi-Fi router
- Before wiring work related to the receiver must be carried out only when de-energized
- Connect your receiver to the power supply.
Following your installation an order of pairing must be respected for a correct RF initialisation.
Installation 1: Receiver BT-WR02 H&C RF + RF thermostat BT-XX02/BT-XX03
- The receiver must be put in RF pairing mode by 10sec pressing on the button.
- The RF LED should be orange slow flashing, indicating that the Receiver is now in radio configuration mode waiting for a thermostat configuration address.
- Please refer to the thermostat leaflet for enter the thermostat in RF pairing mode.
- The receiver RF LED must be switched OFF and the thermostat should exit the RF init mode to indicate correct pairing between both elements.
Installation 2: Receiver BT-WR02 H&C RF + RF Thermostat BT-XX02/BT-XX03 + central unit BT-CT02 RF
- Link first the thermostat with the smart home.
- The receiver must be put one time more in RF pairing mode by 10 sec pressing on the button.
- Then the RF LED should be orange slow flashing, indicating that the receiver is now in radio pairing mode waiting for a thermostat configuration address.
- Please refer to the Central leaflet for more explanation about the pairing mode “RF Init”. Pair only in heating mode or hydraulic circuit mode.
- The receiver RF LED must be switched OFF and the Central will show a message to indicate correct pairing between both elements.
Remarks:
- In case of loss RF communication (RF Alarm), the receiver will stop heating or cooling.
