- Press temperature adjustment buttons.
- Thermostat maintains new setting until the next schedule period begins.
This allows flexibility during unexpected routine changes.
Alerts and Maintenance Reminders
The thermostat displays alert codes to help identify system issues or maintenance needs.
Common Alert Codes
| Code | Meaning |
| 405 | Low battery warning |
| 407 | Critically low battery |
| 164 | Heat pump fault detected |
| 170 | Thermostat memory issue |
| 173 | Internal sensor error |
| 178 | Outdoor sensor fault |
| 181 | Air filter replacement reminder |
Responding promptly to alerts helps maintain system efficiency.
Compressor Protection Feature
The thermostat includes built-in protection to prevent equipment damage.
Restart Delay Behavior
- Display may show “Waiting for Equipment”
- System restart may be delayed about five minutes
- Prevents short cycling of compressor
Avoid repeated rapid temperature changes during this delay period.
Cooling Safety Recommendation
Do not operate cooling mode when outdoor temperature is below 50°F (10°C) to avoid system damage.
Troubleshooting Common Problems
Blank Thermostat Screen
Check the following:
- Circuit breaker power supply
- HVAC system power switch
- Furnace door panel position
Unable to Adjust Temperature
Possible reasons include:
