During DRY operation, the system adjusts the room 
temperature and fan speed according to the conditions in the 
room, in order to maintain a comfortable room environment.

DRY operation is as shown in the figure below.

  In order to further improve inverter performance, control is 

switched between PWM control at low operation speeds, and 
PAM control at high operation speeds, making the most 
effective use of power.

The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.

The compressor operates at a low operating frequency.
The indoor fan operates with 1/f fluctuation.

  Monitoring operation takes place when the room temperature 

is below 15  C, or more than 3  C below the set temperature.

  When the monitoring range is entered, the compressor stops, 

and the indoor fan operates with 1/f fluctuation.

Conditions are monitored at all 
times when the room temperature 
is below 15  C.

  The set temperature is 2  C below the detected room 

temperature in the case of cooling operation, and 2  C 
above the room temperature in the case of heating 
operation. The flap and fan speed settings are AUTO.

  When AUTO mode is selected, the microprocessor calculates 

the difference between the set temperature and the room 
temperature, and automatically switches to Cooling or 
Heating mode.

  As shown by the example in the figure below, with AUTO 

cooling/heating operation, the mode changes between 
Heating and Cooling mode according to changes in the 
relationship between the current room temperature and the 
set temperature.

Example

Example of operation in AUTO mode with the set room temperature 

at 23  C.

To operate the system, press the OPERATION button, 

which is also used as the receiver, below the unit display. 

Each time this button is pressed, the OPERATION lamp 

changes color to indicate the type of operation. Select the 
desired type of operation.

The Sensor Dry operation during the Low Ambient Cooling 
Mode (outside air temperature:15  C or lower) is as follows. 

The compressor operates a cycle of 3 minutes ON and 6 
minutes OFF repeatedly.
