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.

5-22. FORCED COOLING OPERATION
5-22. COMPRESSOR STOP CONTROL
When the detection value of outdoor temperature sensor is lower than temperature
in the table below, the compressor is stopped.
(Table 15 : Operation temperature of compressor stop control)

4. COOLING PRESSURE OVERRISE PROTECTION
When the outdoor unit heat exchange sensor temperature rises to 67°C or greater,
the compressor is stopped and trouble display is performed.
After 3 minutes ST, release of protection.
3. ANTIFREEZING CONTROL (Cooling and Dry mode)
The compressor frequency is decrease on cooling & dry mode when the indoor heat exchanger
temperature sensor detects the temperature lower than Temperature .
Then, the anti-freezing control is released when it becomes higher than Temperature .
(Table 14 : Anti-freezing Protection Operation / Release Temperature)

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.
73Hz or greater 70Hz
