1. CAPACITY CONTROL
1-1 COOLING, HEATING, DRY CAPACITY CONTROL
Compressor frequency decides by capacity of an indoor unit, operation number of an indoor unit,
set temperature, room temperature and outside temperature.
When the air conditioner is set to the AUTO mode by remote control, operation starts in the optimum
mode from among the HEATING, COOLING and MONITORING modes. During operation, the
optimum mode is automatically swiched in accordance with temperature changes. The temperature
can be set between 18°C and 30°C in 1 degC steps.
When operation starts, only the indoor fan is operated for 1 minute. (Air flow mode: S- Lo)
After 1 minute, depends on the room temperature and outdoor unit's operarion mode,
the operation mode is selected in accordance with the table below.
( Table 1 : Operation mode selection table )

When COOLING was selected at , the same operation as COOLING OPERATION is performed.
When HEATING was selected at , the same operation as HEATING OPERATION is performed.
When the compressor was stopped for 6 consecutive minutes by the temperature control function
after the COOLING or HEATING operation mode was selected at above, operation is switched
to MONITORING and the operation mode is selected again.

4. HEATING OPERATION
When the airflow is set to [AUTO], the indoor fan
motor operates [MED] mode.
Then the indoor fan motor will run according
to a room temperature, as shown in Figure 2.
On the other hand, if switched in [HIGH] [QUIET],
the indoor motor will run at a constant airflow
of [HEAT] operation modes QUIET, LOW, MED, HIGH,
as shown in Table 2.

1. Outdoor Fan Motor
*It runs at 500rpm for 20 seconds after starting up the outdoor fan.
When the outdoor heat exchanger tenperature is lower than 1°C,
