If you see “FP” on your indoor unit's display, it means Freeze Protection mode is active. This feature keeps the temperature at 10°C (46°F) to help prevent pipes and other items in your space from freezing.
How to Activate Freeze Protection Mode:
Set the unit to Heating mode.
Lower the temperature to the minimum setting.
Press the down arrow button on your remote twice in a row.
The “FP” code will appear on the display once the mode is activated.
