NOTE
Notes on batteries

When replacing the batteries, use batteries of the same type, and replace both old batteries together.

When the system is not used for a long time, take the batteries out.
The batteries will last for approximately 1 year. However, if the remote controller display begins to fade and degradation of reception performance occurs within a year, replace both batteries with new size AAA.LR03 (alkaline).

The attached batteries are provided for the initial use of the system.
The usable period of the batteries may be short depending on the manufactured date of the air conditioner.

Notes on the remote controller

Never expose the remote controller to direct sunlight.
Dust on the signal transmitter or receiver will reduce the sensitivity. Wipe off dust with soft cloth.

Signal communication may be disabled if an electronicstarter-type uorescent lamp (such as inverter-type lamps) is in the room. Consult the shop if that is the case.
If the remote controller signals happen to operate another appliance, move that appliance to somewhere else, or consult the service shop.

When the remote controller is not in use, please close the slide cover to prevent failure.

NAMES AND FUNCTIONS OF REMOTE CONTROLLER

REMOTE CONTROLLER

This controls the operation of the indoor unit. The range of control is about 7 meters. If indoor lighting is controlled electronically, the range of control may be shorter.
This unit can be fixed on a wall using the fixture provided. Before fixing it, make sure the indoor unit can be controlled from the remote controller.
Handle the remote controller with care. Dropping it or getting it wet may compromise its signal transmission capability.
After new batteries are inserted into the remote controller, the unit will initially require approximately 10 seconds to respond to commands and operate.
When remote controller is not in use for about 3 minutes during OFF condition, indicated by on the display, the LCD will turn off.
During clock setting, the LCD will turn off about 10 minutes later if the remote controller is not in use.
When pressing any button, the LCD will turn on.

Precautions for Use

Do not put the remote controller in the following places.
Under direct sunlight.

In the vicinity of a heater.
Handle the remote controller carefully. Do not drop it on the floor, and protect it from water.
Once the outdoor unit stops, it will not restart for about 3 minutes (unless you turn the power switch off and on or unplug the power cord and plug it in again).

This is to protect the device and does not indicate a failure.
If you press the MODE selector button during operation, the device may stop for about 3 minutes for protection.

VARIOUS FUNCTIONS

◼ Auto Restart Control

◼ If there is a power failure, operation will be automatically restarted when the power is resumed with previous operation mode and airflow direction.
(As the operation is not stopped by remote controller.)
◼ If you intend not to continue the operation when the power is resumed, switch off the power supply.
When you switch on the circuit breaker, the operation will be automatically restarted with previous operation mode and airflow direction.
Note:

If you do not require Auto Restart Control, please consult your sales agent.
Auto Restart Control is not available when Timer or Sleep Timer mode is set.

AUTOMATIC OPERATION
The device will automatically determine the mode of operation, HEAT or COOL depending on the current room temperature. The selected mode of operation will change when the room temperature varies.
However, the mode of operation will not change when indoor unit is connected to multi type outdoor unit.◼ As the settings are stored in the memory of the remote controller, you only have to press the (START/STOP) button next time.
Press the (FAN SPEED) button to select AUTO, HIGH, MED, LOW or SILENT.

HEATING OPERATION

◼ Use the device for heating when the outdoor temperature is under 21°C.

◼ As the settings are stored in the memory of the remote controller, you only have to press the (START/STOP) button next time.
◼ During AUTO fan, the fan speed automatically changes as below:
◼ When the difference between room temperature and setting temperature is large, fan starts to run at HI speed.
◼ After room temperature reaches the preset temperature, fan speed will be changed to lower speed to obtain optimum room temperature condition for natural healthy heating.

Defrosting
Defrosting will be performed about once an hour when frost forms on the heat exchange of the outdoor unit, for 5~10 minutes each time.
During defrosting operation, the operation lamp blinks in a cycle of 3 seconds on and 0.5 second off.
The maximum time for defrosting is 20 minutes.
However, if the indoor unit is connected to multi type outdoor unit, the maximum time for defrosting is 15 minutes.
(If the piping length used is longer than usual, frost is likely to form.)

DEHUMIDIFYING OPERATION

Use the device for dehumidifying when the room temperature is over 16°C.
When it is under 15°C, the dehumidifying function will not work.
