| Display | Backlit, easy to read |
|---|---|
| Early Start | Learns heating/cooling time to reach set temperature |
| Compressor protection | 5‑minute wait before restart |
Press the backlight button to activate the display, then follow the instructions on page 7 to set the time.
It prevents damage by forcing the compressor to wait five minutes before restarting, flashing an icon during the wait period.
Press the setpoint button to temporarily override the temperature setpoint; see page 14 for details.
Early Start learns how long your heating or cooling system takes to reach the desired temperature and activates it early so the set temperature is reached at the scheduled time.
