Emergency operation

SENSOR DRY

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.

SENSOR DRY operation

DRY operation is as shown in the figure below.

PAM- control

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 59°F

(

15°C), or more than 5°F

(

3°C) below the set

temperature.

When the monitoring range is entered, the compressor stops,

and the indoor fan operates with 1/f fluctuation.
