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.

*If it's Middle zone, operation mode of indoor unit is selected as below.

(1). Same operation mode is selected as outdoor unit.

If outdoor unit is operating in Cooling, Dry, and Heating mode,

indoor unit will be operated by the same operation mode.

(2). Selected by the outdoor temperature.

If outdoor unit is operating in other than Cooling, Dry, and Heating mode,

indoor unit will be operated according to the outdoor temperature as below.
