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 controller, operation starts in the optimum
mode from among the Heating, Cooling, Dry and Monitoring mode. During operation, the
optimum mode is automatically switched in accordance with temperature changes. The temperature
can be set between 18°C and 30°C in 1°C steps.
When operation starts, indoor fan and outdoor fan are operated for around 3 minutes.
Room temperature and outdoor temperature are sensed,
and the operation mode is selected in accordance with the table below. <Monitoring mode>
Cooling mode
25°C Heating mode
( Table 1 : Operation mode selection table )
Room temperature (TR)
TR> Ts + 2°C
Ts + 2°C TR Ts - 2°C *Middle zone
TR < Ts - 2°C Heating
When Cooling or Dry mode was selected at and air flow mode is Auto, the air conditioner operates as follow.
The same operation as COOLING OPERATION AND DRY OPERATION.
When the room temperature has remained at set temperature -1.5°C,
operation is automatically switched to Dry mode.
If the room temperature reaches set temperature +2°C during Dry mode, operation returns to Cooling.

The airflow can be switched in 5 steps such as Auto, Quiet, Lo, Me, Hi,
while the indoor fan only runs.
When Fan mode is set at (Auto), it operates on (Me) Fan Speed.
2. FAN OPERATION
3. COOLING OPERATION (Auto : Cooling)
Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature,
as shown in Fig 3.
On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow of [Cooling]
operation modes Quiet, Lo, Me, Hi.
