4.3. Pairing with a Zigbee Gateway
To utilize the smart features of your thermostat, it must be paired with a compatible Zigbee gateway (hub).
- Put your Zigbee gateway into pairing mode. Refer to your gateway's instruction manual for specific steps.
- On the Comet Zigbee thermostat, press and hold the middle button (usually indicated by "...") for approximately 3 seconds until the display shows a pairing symbol or "PAIR".
- The thermostat will search for the gateway. Once successfully paired, the display will confirm the connection (e.g., by showing the current temperature or a network symbol).
- If pairing fails, ensure the thermostat is within range of the gateway and repeat the process.

5. Operating the Thermostat
5.1. Manual Temperature Adjustment
You can manually adjust the desired temperature directly on the device:
- Use the Up (▲) and Down (▼) buttons to increase or decrease the target temperature.
- The new temperature will be displayed and then the device will return to showing the current temperature or valve position.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Batteries are not inserted correctly or are depleted. | Check battery polarity. Replace batteries if necessary. |
| Cannot pair with Zigbee gateway. | Gateway not in pairing mode; thermostat out of range; interference. | Ensure gateway is in pairing mode. Move thermostat closer to gateway. Check for other Zigbee devices causing interference. Reset thermostat and try again. |
| Thermostat not controlling heating effectively. | Incorrect mounting; valve stuck; air in radiator. | Ensure thermostat is securely mounted. Check if the radiator valve pin moves freely. Bleed the radiator if it's not heating evenly. |
| Display shows error code or unexpected behavior. | Temporary malfunction; software issue. | Remove and reinsert batteries to perform a soft reset. If the problem persists, contact customer support. |
