Wiring Diagram
Warning: No live wiring. Keep all wire ends concealed. As some circuits of this product involve high-voltage electricity, installation should be carried out by qualified professionals.
The receiver connects to the boiler via passive contacts. The wiring typically involves connecting to NO (Normally Open) and COM (Common) terminals for most boilers. However, some boilers may require wiring to COM and NC (Normally Closed) terminals.

Figure 7: Receiver wiring diagram for boiler connection.
| Terminal Block | Controlling Device | Wiring Instructions |
|---|---|---|
| NO1 | Normally-Closed Electric Actuator | Connect to NO1 and N |
| NC1 | Normally-Open Electric Actuator | Connect to NC1 and N |
| M | External Circulation Pump <5A | Connect to M and N |
Device Pairing (Thermostat and Receiver)
- With the device powered on, long press the pairing key on the receiving panel until its signal light starts to flash.
- Long press the 'V' key on the transmitting panel (thermostat) until the signal light on the receiving panel stops flashing.
- In heating mode, set the temperature above the current room temperature. If the device sends a signal and all three indicator lights on the receiving panel are lit, the pairing is successful.
