TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• 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 conditioner 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.

CAUTION

• Depending on the electric power, use the wattmeter for remote reading by sending the pulse signal.

• Use the wattmeter with the pulse width of 50 ms ~ 400 ms.

• The wattmeter pulse must be able to sink at least 3 mA or more of current in the power indicator.

• Use the wattmeter of 1 W/pulse, 2 W/pulse, 4 W/pulse, 6 W/pulse, 8 W/pulse, 10 W/pulse, 100 W/pulse and PT/CT (1 ~ 50 000).

• When setting the wattmeter, set it to Master Mode.

• Maximum of 8 wattmeters can be installed.

• The distance between power indicator and wattmeter should be shorter than 10 m in normal circumstance.

• When electrical or mechanical noise is expected, more shorter wiring is needed.
