This setting can make the room temperature control more suitable for homes or buildings
with high insulation (Function Number 95).
When the thermo sensor is turned ON it controls the compressor frequency at
initial start to prevent overshoot in heating or cooling.
When room temperature is controlled by the Indoor unit sensor, compressor operation
is as shown in Fig. 14 and 15 .
But, adjustment is possible by the room temperature correction function setting.
(Function Number 30 or 31)
When room temperature is controlled by the Wired remote sensor, compressor
operation is as shown in Fig. 16 and 17 .
But, adjustment is possible by the room temperature correction function setting.
(Function Number 92 or 93)
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 blinks simultaneously while the unit is on the FORCED COOLING OPERATION.
It is released after 60 minutes from starting time.
