WATTS BT-WR02 Wireless Wall Receiver
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 an
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-x02 BT-x03 range)
The cooling relay is used to manage an actuator for a cold water circuit. (Not
available with BT-A02 RF thermostats)
This couple (thermostat BT-x02 or BT-x03 and receiver BT-WR02 H&C RF) can also
be managed by a Central unit BT-CT02 RF to have full control of your heating
installation from one point. In that case, the receiver works always in the
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
wastewater.eu.With a BT-D02 RF / BT-D03 RF and BT-DP02 RF it is possible to
configure the receiver in manual mode, heating mode, cooling mode or automatic
mode (Please refer to the BT-Dx02 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 the case of setpoint 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 a timer is applied before switching from
heating to cooling or from cooling to heating.
Compatibility matrix:
The receiver is delivered with 2 outputs in free contact mode. To trigger the outputs in live contact, linked the live on 1 point of each connector using the cable supplied in the box.

Installation and RF pairing rules
Install and plug the receiver into the following guidelines to guarantee an optimal reception:
- The receiver must be put at a minimum distance of 50cm from all other electrical or wireless materials like GSM, a Wi-Fi routers.
- 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 initialization.
Installation 1: Receiver BT-WR02 H&C RF + RF thermostat BT-x02
- 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 entering 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 the correct pairing between both elements.
Installation 2: Receiver BT-WR02 H&C RF + RF Thermostat BT-x02+ 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 the correct pairing between both elements
Remarks: – In case of loss RF communication (RF Alarm), the receiver will stop heating or cooling.
