8-5. Dry Operation (Dehumidification)

Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.

Room temp.

T + 4°F (2°C)

Set temp. T°C T – 2°F (1°C)

Room temp. 59°F (15°C)

Cooling operation

* Dry A Zone

 

Compressor:

Continuous operation

FMI (indoor fan):

L (low speed)/LL (very low speed) intermittent ventilation only while the compressor is ON.

 

 

* Dry B Zone

 

Compressor:

Intermittent operation (ON for 3 minutes and OFF for 9 minutes)

FMI (indoor fan):

L (low speed)/LL (very low speed) intermittent ventilation only while the compressor is ON.

Monitor Zone

Both the indoor and outdoor units stop.

NOTE

Intermittent ventilation occurs by switching the indoor fan speed between L LL.

Dry operation does not occur when the room temperature is under 59°F (15°C), which is the Monitor Zone.

When the compressor stops, the indoor fan stops as well.
