ESPAÑOL

• Do not cool excessively indoors. This may be harmful for your health and may consume more

electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air condi-

tioner is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the

air flow or weaken the cooling / dehumidifying functions.

line connection

AHU sensor connection

• 2 outdoor units can be connected to

communication PCB 1EA, so be careful

not to have mixed connection of the pipe

temperature sensor and communication

line that are connected to 1 outdoor unit.

• You must install temperature/humidity

sensor to SA duct and RA duct that com-

ply with the specification.

(Specification: -40 °C~70 °C,

RH 0~95 % / AC 24 V / DC 0~10 V)

•

If only temperature sensor is installed to SA/

RA duct, you do not need to set Dip switch.

•

According to the installation site, set the

Dip switch according to the setting method.

• Be careful of the Dip switch setting accord-

ing to whether outdoor unit is connected.

• During the connection of outdoor unit,

make sure to set all rotary switches to be

different.

• After completing CONTROL KIT installa-

tion, make sure to set outdoor unit
