The compressor frequency is
decreased 2Hz every 60seconds.
Release of protection
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.
