[Operating instructions]

1Check the function settings.

2 Press the

CHECK

button twice continuously. CHECK is lit and “00” blinks.

Press the temp

button once to set “50”. Direct the wireless remote controller toward the receiver of the indoor unit and press

the

h

button.

 

3Set the unit number.

Press the temp button to set the unit number. (Press “01” to specify the indoor unit whose unit number is 01.)

Direct the wireless remote controller toward the receiver of the indoor unit and press the

min

button.

By setting unit number with the

min

 

button, specified indoor unit starts performing fan operation.

Detect which unit is assigned to which number using this function. If unit number is set to AL, all the indoor units in same refrigerant system start performing fan operation simultaneously.

*If a unit number that cannot be recognized by the unit is entered, 3 beeps of 0.4 seconds will be heard. Reenter the unit number setting.

*If the signal was not received by the sensor, you will not hear a beep or a “double ping sound” may be heard. Reenter the unit number

setting.

4Select a mode.

Press the temp

button to set a mode. Press “24” to turn on the function that raises the set temperature by 4 degree

during heat operation. Direct the wireless remote controller toward the sensor of the indoor unit and press the

h

button.

The sensor-operation indicator will blink and beeps will be heard to indicate the current setting number. Current setting number: 1 = 1 beep (one second)

2 = 2 beeps (one second each)

3 = 3 beeps (one second each)

*If a mode number that cannot be recognized by the unit is entered, 3 beeps of 0.4 seconds will be heard. Reenter the mode number.

*If the signal was not received by the sensor, you will not hear a beep or a “double ping sound” may be heard. Reenter the mode

number.

 

 

5 Select the setting number.

 

Press the temp

button to select the setting number. (02: Not available)

h

Direct the wireless remote controller toward the receiver of the indoor unit and press the

button.

The sensor-operation indicator will blink and beeps will be heard to indicate the setting number.

Setting number: 1 = 2 beeps (0.4 seconds each)

2 = 2 beeps (0.4 seconds each, repeated twice)

3 = 2 beeps (0.4 seconds each, repeated 3 times)

*If a setting number that cannot be recognized by the unit is entered, the setting will turn back to the original setting.

*If the signal was not received by the sensor, you will not hear a beep or a “double ping sound” may be heard. Reenter the setting number.

6 Repeat steps 4 and 5 to make an additional setting without changing unit number.

7 Repeat steps 3 to 5 to change unit number and make function settings on it.

8 Complete the function settings

Press button.

*Do not use the wireless remote controller for 30 seconds after completing the function setting.
