• Two remote controls for operation in different rooms

• Auto restart function in case of power failure

• Repeat timer can turn the unit on/off every day at the same time.

• Only preset air conditioners can be stopped by pressing the ZONE CONTROL b utton.

• Energy saving operation
ENERGY SAVE mode uses a computer program to economically control unit operation by rais­ing the set temperature slightly in the cooling mode and lowering the set temperature in the heat­ing mode. If you press the ENERGY SAVE button while the air conditioner is on, it will change to

the conservation mode. If you press the ENERGY SAVE button while the unit in the timer mode
(ON timer, PROGRAM timer or REPEAT timer), the unit will go into the conservation mode when
the unit starts with the timer.

• ARG7R/9A/9R/12R have a chargeless design.

• When the connection piping length exceeds 7.5m, the ARG14R/18R/18RH
require an additional charge of 20g/m (14R) and 50g/m(18R/18RH).
