11-1. COOL ( ) 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.

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 lowers during cool mode operation, low outside temperature operation starts, and the outdoor fan slows or stops.

11-2. DRY ( ) 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. (11-1.1.)

2.Low outside temperature operation

Low outside temperature operation is as same as COOL mode. (11-1.2.)

11-3. HEAT ( ) 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.

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 temperature is low or when defrosting is being done, the indoor fan will stop or rotate in Very Low speed.

2.High pressure protection

In HEAT operation the compressor operational frequency is controlled by the temperature of the indoor heat exchanger to prevent the condensing pressure from increasing excessively.

3.Defrosting

Defrosting starts when the temperature of outdoor heat exchanger becomes too low. The indoor/outdoor fans stop, the 4-way valve reverses, and the compressor starts.

This mode continues until the temperature of outdoor heat exchanger rises or the fixed time passes.

11-4. FAN( d )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.
