- Inspection: Annually, have a qualified electrician inspect the wiring connections to ensure they remain secure and free from corrosion.
- Avoid Obstruction: Ensure the thermostat is not covered or obstructed, as this can affect its temperature sensing capabilities.
8. Troubleshooting
If you encounter issues with your UTH-170 thermostat, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat has no power/display is off. | No power from circuit breaker; loose wiring connection. | Check circuit breaker and ensure it is ON. Verify wiring connections (power off first). |
| Heating system not turning on. | Temperature set too low; 12-hour shutdown active; faulty heating element; loose heating wire connection. | Increase set temperature. Reset thermostat if 12-hour shutdown is active. Check heating element and wiring (power off first). |
| Inaccurate temperature reading. | Sensor improperly placed or damaged; thermostat exposed to drafts/heat sources. | Ensure sensor is correctly installed and undamaged. Relocate thermostat if necessary. |
| Thermostat turns off after 12 hours unexpectedly. | Automatic shutdown feature is active. | This is a normal function. Manually reactivate the thermostat to resume heating. |
If the problem persists after attempting these solutions, please contact customer support or a qualified electrician.
