9-1. Operation Functions

Emergency operation

Emergency operation is available when the remote controller malfunctions, has been lost, or otherwise cannot be used.

To operate the system, press the OPERATION button, which is also used as the receiver, below the unit display. Each time this button is pressed, the OPERATION lamp changes color to indicate the type of operation. Select the desired type of operation.

COOLHEATSTOP

(Lamp Off)

The set temperature is 2°C below the detected room temperature in the case of cooling operation, and 2°C above the room temperature in the case of heating operation. The flap and fan speed settings are AUTO.

AUTO cooling/heating operation

Selecting the operation mode

When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and the room temperature, and automatically switches to Cooling or Heating mode.

Room temp. Set temp. COOL Room temp. Set temp. HEAT

As shown by the example in the figure below, with AUTO cooling/heating operation, the mode changes between Heating and Cooling mode according to changes in the relationship between the current room temperature and the set temperature.

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.

Conditions are monitored at all times when the room temperature is below 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 15°C, or more than 3°C below the set temperature.

When the monitoring range is entered, the compressor stops, and the indoor fan operates with 1/f fluctuation.

PAM-αcontrol

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.
