3.5 Pairing Thermostat with Receiver
The thermostat and receiver are usually pre-paired. If re-pairing is needed:
- On the receiver, press and hold the pairing button until the middle indicator light starts flashing.
- On the thermostat, press the 'Up' arrow button for 5 seconds until the communication icon (usually a signal tower) appears and flashes on the display.
- Once successfully paired, the middle indicator light on the receiver will become solid, and the communication icon on the thermostat will stop flashing.
3.6 Connecting to Wi-Fi and App
To enable smart control features, connect your thermostat to your home Wi-Fi network (2.4GHz only).
- Download the 'Smart Life' or 'Tuya Smart' application from your smartphone's app store (Google Play Store or Apple App Store).
- Register or log in to your account in the app.
- On the thermostat, press and hold the 'Up' arrow button for 5 seconds until the Wi-Fi icon on the display starts flashing. This puts the thermostat into pairing mode.
- In the app, follow the on-screen instructions to add a new device. Select 'Temperature Sensor' or 'Thermostat' from the device list.
- Enter your 2.4GHz Wi-Fi network name and password when prompted.
- The app will guide you through the connection process. Once connected, the Wi-Fi icon on the thermostat will become solid.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not turning on. | No power (dead batteries or USB not connected/faulty). | Replace batteries or ensure USB power supply is working. |
| Heating system not responding. | Incorrect wiring of the receiver to the boiler; receiver not powered; thermostat not paired with receiver. | Verify receiver wiring (L/N for power, K1/K2 for boiler control). Ensure receiver has power. Re-pair thermostat and receiver (Section 3.5). |
| Wi-Fi connection fails. | Incorrect Wi-Fi password; 5GHz Wi-Fi network used; thermostat not in pairing mode; router too far. | Ensure correct 2.4GHz Wi-Fi network and password. Put thermostat in Wi-Fi pairing mode (flashing Wi-Fi icon). Move thermostat closer to router if necessary. |
| Inaccurate temperature reading. | Thermostat placed in an unsuitable location (direct sun, draft, near heat source); sensor calibration needed. | Relocate thermostat. Use temperature compensation feature in settings to calibrate the sensor. |
| Loss of pairing between thermostat and receiver after power cut. | Interference or temporary communication loss. | Re-pair the thermostat and receiver as described in Section 3.5. |
| Thermostat buttons unresponsive. | Child lock activated; device malfunction. | Deactivate child lock (refer to thermostat display or app). If issue persists, contact support. |
