Fan Operation Settings
Proper fan configuration improves indoor air circulation and comfort.
Fan Mode Options
| Fan Mode | Operation Behavior |
|---|---|
| Auto | Runs only during heating or cooling cycles |
| On | Runs continuously |

The circulate option helps maintain consistent airflow distribution without constant fan operation.
Setting Time and Date
Accurate time configuration is required for proper schedule operation.
Configure Time
- Press Menu.
- Select Time.
- Choose 12-hour or 24-hour format.
- Adjust hours and minutes.
- Confirm and save settings.
Configure Date
- Navigate to Menu → Date
- Adjust day, month, and year
- Save changes
If the thermostat is connected to the internet, time settings may sync automatically.
Programming Temperature Schedules
The thermostat supports structured daily scheduling periods.
Typical Schedule Periods
- Wake
- Leave
- Return
- Sleep
Schedule Setup Steps
- Open Menu → Schedule.
- Enable scheduling feature.
- Select a schedule period.
- Set desired time.
- Adjust heating and cooling temperature setpoints.
Programming schedules helps reduce energy usage during inactive hours.
Temporary Temperature Override
To manually adjust comfort settings:
- Use temperature adjustment buttons on the main screen.
- The thermostat will temporarily override scheduled settings until the next programmed period begins.
This feature is useful during unexpected routine changes.
Compressor Protection Feature
The thermostat includes built-in equipment protection logic.
Compressor Delay Behavior
- Screen may display “Waiting for Equipment”
