6.2. Selecting Operating Mode
Use the Operating Mode Selector to choose one of the following modes:
- OFF: The system is turned off.
- HEAT: The system will activate heating when the room temperature falls below the set point.
- COOL: The system will activate cooling when the room temperature rises above the set point.
- FAN: The fan operates continuously without heating or cooling.
6.3. Adjusting Fan Speed

- Ensure the thermostat is not obstructed by furniture or curtains, which could affect temperature readings.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat not responding | No power; incorrect wiring | Check circuit breaker; verify wiring connections (consult a qualified electrician). |
| HVAC system not turning on/off | Incorrect mode selected; temperature setting too close to ambient | Ensure correct operating mode (HEAT/COOL) is selected; adjust temperature setting to be significantly different from current room temperature. |
| Inaccurate temperature reading | Thermostat exposed to drafts or heat sources; obstructed sensor | Relocate thermostat if possible; remove obstructions; clean dust from sensor area. |
If the problem persists after attempting these solutions, contact customer support or a qualified HVAC technician.
