8-1. COOL (  ) OPERATION

8-1. COOL ( 1.Coil frost prevention ) OPERATION

(1)Press OPERATE/STOP (ON/OFF) button.

OPERATION INDICATOR lamp of the indoor unit turns on with a beep tone.

(2)Select COOL mode with OPERATION SELECT button.

(3)Press TEMPERATURE buttons (TOO WARM or TOO COOL button) to select the desired temperature. The setting range is 61 ~ 88 °F (16 ~ 31 °C).

1.Coil frost prevention

When the temperature of indoor heat exchanger becomes too low, the coil frost prevention mode works.

The indoor fan operates at the set speed and the compressor stops. This mode continues until the temperature of indoor heat exchanger rises.

2.Low outside temperature operation

When the outside temperature is lower, low outside temperature operation starts, and the outdoor fan slows or stops.

8-2. DRY ( 2.Low outside temperature operation ) OPERATION

(1)Press OPERATE/STOP (ON/OFF) button.

OPERATION INDICATOR lamp of the indoor unit turns on with a beep tone.

(2)Select DRY mode with OPERATION SELECT button.

(3)The set temperature is determined from the initial room temperature.

1.Coil frost prevention

Coil frost prevention is as same as COOL mode. (8-1.1.)

2.Low outside temperature operation

Low outside temperature operation is as same as COOL mode. (8-1.2.)

8-3. HEAT ( 8-2. DRY (  ) OPERATION ) OPERATION (MSZ)

(1)Press OPERATE/STOP (ON/OFF) button.

OPERATION INDICATOR lamp of the indoor unit turns on with a beep tone.

(2)Select HEAT mode with OPERATION SELECT button.

(3)Press TEMPERATURE buttons (TOO WARM or TOO COOL button) to select the desired temperature. The setting range is 61 ~ 88 °F (16 ~ 31 °C).

1.Cold air prevention control

When the compressor is not operating or is starting, and the temperature of indoor heat exchanger and/or the room tem- perature is low or when defrosting is being done, the indoor fan will stop or rotate in Very Low speed.

2. High pressure protection

The compressor operational frequency is controlled by the temperature of the indoor heat exchanger to prevent the con- densing pressure from increasing excessively.

When the temperature of indoor heat exchanger becomes too high, the high pressure protection works.

The indoor fan operates following the cold air prevention control. This mode continues until the temperature of indoor heat exchanger falls.

3.Defrosting

Defrosting starts when the temperature of outdoor heat exchanger becomes too low.

The compressor stops once, the indoor/outdoor fans stop, the 4-way valve reverses and the compressor re-starts. This mode continues until the temperature of outdoor heat exchanger rises or the fixed time passes.

8-4. FAN( 8-3. HEAT (  ) OPERATION (MSZ) )OPERATION (MSY)

(1)Press OPERATE/STOP (ON/OFF) button.

OPERATION INDICATOR lamp of the indoor unit turns ON with a beep tone.

(2)Select FAN mode with OPERATION SELECT button.

(3)Select the desired fan speed. When AUTO, it becomes Low. Only indoor fan operates. Outdoor unit does not operate.

8-5. “I FEEL CONTROL” ( 1.Cold air prevention control2. High pressure protection ) OPERATION (MSY)

(1)Press OPERATE/STOP (ON/OFF) button on the remote controller. OPERATION INDICATOR lamp of the indoor unit turns on with a beep tone.

(2)Select “I FEEL CONTROL” mode with OPERATION SELECT button.

(3)The operation mode is determined by the room tempera- ture at start-up of the operation.

Initial room temperature

Mode

 

 

77 °F (25 °C) or more

COOL mode of

"I FEEL CONTROL"

 

more than 55 °F (13 °C),

DRY mode of

less than 77 °F (25 °C)

"I FEEL CONTROL"

Once the mode is fixed, the mode does not change by room temperature afterwards.

Under the ON TIMER ( 3.Defrosting ) operation, mode is determined according to the room temperature at the set time the operation starts.
