9 Operation Details

9.1. BASIC FUNCTION

Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air temperature.

9.1.1. Internal Setting Temperature

Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting processes. These shifting processes are depending on the air conditioner settings and the operation environment. The final shifted value will be used as internal setting temperature and it is updated continuously whenever the electrical power is supplied to the unit.

9.2. Indoor Power Relay Control

The Power Relay turns on under the followin g conditions.

1. For three minutes, when plugged in the A/C or the Error Reset button on remote controller is pressed.

2. During Installation Check Mode and following for three minutes after checking.

3. During On-timer sampling and during Preliminary operation.

4. During Operation and following for three minutes after the operation is stopped.

5. During Auto Operation, Test run, Forced Heating or Odour Removal Operation and following for three minutes after the operation is stopped.

9.3. Room Air Temperature Control (Compressor Control)

Operating frequency of a compressor is decided according to temperature differences between remote controller setting and room temperatures. A relative method which gives frequency changes, based on the decided frequency, will provide you with comfortable room environment that is not affecte d by operating conditions.
