4. C OOLING PRESSURE OVERRISE PROTECTION
When the outdoor unit heat exchange sensor temperature rises to 65°C or greater,
the compressor is stopped and trouble display is performed.
5. HIGH TEMPERATURE RELEASE CONTROL ( HEATING MODE )
On heating mode, the compressor frequency is controlled as following based on the
detection value of the indoor heat exchanger temperature sensor.
(Fig.18 : Heating Overload Protection Control)

The forced cooling operation starts up when MANUAL / AUTO button is pressed more than 10 seconds.
During the forced cooling operation, it keeps operation regardless of detection value of room temperature sensor.
Operation LED and Timer LED light up while the unit is on the forced cooling operation.
The forced cooling operation is released after 60 minutes from starting time.
