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.
DRY operation is as shown in the figure below.

Conditions are monitored at all
times when the room temperature
is below 59°F(15°C).
DRY A
The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.
DRY B
The compressor operates at a low operating frequency.
The indoor fan operates with 1/f fluctuation.
Monitor
Monitoring operation takes place when the room temperature
is below 59°F 15°C), or more than 5°F
(
