Maintenance
- Battery Replacement: When the low battery indicator appears, replace the AA batteries promptly. Open the battery compartment, remove old batteries, and insert new ones, observing polarity.
- Filter Change Reminder: The thermostat can display a "Change Filter" indicator. Replace your HVAC system's air filter as recommended by the manufacturer, then reset the reminder on the thermostat.
- Cleaning: Wipe the thermostat's display and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat display is blank. | No power, dead batteries, or tripped circuit breaker. | Check batteries and replace if necessary. Ensure power is on at the circuit breaker. Verify wiring connections. |
| System not heating/cooling. | Incorrect mode selected, setpoint not reached, or system malfunction. | Ensure thermostat is in "Heat" or "Cool" mode. Adjust setpoint. Check HVAC system for power or error codes. |
| Temperature readings are inaccurate. | Thermostat location, drafts, or calibration issue. | Ensure thermostat is not in direct sunlight or near heat sources/drafts. Check calibration settings in the menu. |
| Programming schedule not working. | Incorrect schedule settings or thermostat in "Hold" mode. | Review and correct programming settings. Cancel any active "Hold" settings. |
