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.

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.
