5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not powering on | Dead or incorrectly installed batteries. | Replace batteries with new AA alkaline batteries, ensuring correct polarity. |
| Boiler not responding | Incorrect wiring; boiler power off; thermostat not calling for heat. | Check wiring connections (Section 2.2). Ensure boiler has power. Verify thermostat is set to a temperature higher than the current room temperature. |
| Wi-Fi connectivity issues | Incorrect Wi-Fi password; router too far; 5GHz network selected. | Ensure correct 2.4GHz Wi-Fi network and password. Move thermostat closer to router or use a Wi-Fi extender. Re-pair via the app. |
| Inaccurate temperature reading | Thermostat placed near heat source/draft; sensor obstruction. | Relocate thermostat away from direct sunlight, drafts, or heat-emitting appliances. Ensure sensor is clear. |
