Heat Pump Over Temperature Protection:
In HEAT PUMP Mode, or Heat Pump and Furnace
Mode, if the indoor coil reaches a temperature above
125°F (52°C), the display will flash both the HEAT
PUMP icon and either 99°F or 99°C on the display.
While Over Temperature Protection is activated, the
compressor will not run. It is recommended to increase
airflow by cleaning the filter and opening the vents.
