Note for TIMER settings:

Any interruption of the power supply, such as a blackout or cutting off of a circuit breaker, makes the set internal clock go wrong. In such a case, the TIMER indicator on the indoor unit blinks, and you need to readjust the setting.

12 °F/°C button

•Used for changing the temperature unit. (Initial setting: °F )

•When you press this button, the displayed temperature unit switches to “°C”, and returns to “°F” when you press it again.

•When you press this button, press it gently by using the tip of a ballpoint pen or other small object in correct direction as shown in this figure.

13 ECONOMY button

Starts or stops ECONOMY operation that saves more electricity consumption than the other operations with a conservative adjustment of the room temperature.

When you press the button, the ECONOMY indicator on the indoor unit turns on.

•In COOL mode, the room temperature will be adjusted at a few degree higher than the defined temperature.

In HEAT mode, the room temperature will be adjusted at a few degree lower than the defined temperature.

•Especially in COOL mode, you can have improved dehumidification without significantly lowering the room temperature.

Notes:

•In COOL or HEAT mode, the maximum output of this operation is approximately 70 % of usual air conditioning operation.

•This operation cannot be performed during temperature monitoring by AUTO mode.

14 POWERFUL button

Starts POWERFUL operation that enables quick cooling down or warming up of the room.

When you press the button to start the POWERFUL operation, the indoor unit emits 3 short beeps.

POWERFUL operation is automatically turned off in the following situations:

•Adjusted room temperature reached to the defined temperature in temperature setting in COOL, DRY, or HEAT mode.

•20 minutes have passed after finishing the POWERFUL operation mode setting.

It is not turned off automatically during setting of the POWERFUL operation.

Notes:

•The airflow direction and the fan speed are controlled automatically.

•This operation cannot be performed simultaneously with ECONOMY operation.

To return to normal operation, press the button again. Then the indoor unit emits 2 short beeps.

15 Remote controller display

In this section, all the possible indicators are displayed for description. In actual operation, the display is linked with the button operation, and only shows the necessary indicators for each setting.

16 Signal transmitter

Aim to signal receiver of the indoor unit properly.

• Signal transmit indicator on the remote controller display shows that signal from the remote controller is being transmitted.

•Operating range is approximately 7 m.

•You will hear a beep if the transmitted signal has been sent properly. If there is no beep, press the button on the remote controller again.

Automatic defrosting operation

When outdoor temperature is very low with high humidity, frost may form on the outdoor unit during the heating operation, and it could reduce the operating performance of the product.

For frost protection, a microcomputer-controlled automatic defrost function is equipped in this air conditioner.

If frost forms, the air conditioner will temporarily stop, and defrost circuit will operate briefly (maximum of 15 minutes.) OPERATION indicator on the indoor unit blinks during this operation.

If frost forms on the outdoor unit after the heating operation, the outdoor unit will stop automatically after it operates for a few minutes. Then the automatic defrosting operation starts.

Auto-restart function

In event of power interruption such as a blackout, the air conditioner stops once. But it restarts automatically and performs previous operation when the power supply is resumed.

If any power interruption occurs after the timer is set, counting down of the timer will be reset.

After the power supply is resumed, the TIMER indicator on the indoor unit blinks to notify you that there has been a timer fault. In such a case, reset the timer for your opportune time.

Malfunctions caused by other electrical devices:

Use of other electrical appliances such as an electric shaver or nearby use of a wireless radio transmitter may cause the malfunction of the air conditioner.

If you encounter such a malfunction, turn off the circuit breaker once. Then turn it on again, and resume operation by using the remote controller.
