Installation tips for the remote controller holder
Fix the remote controller holder using the screws supplied
with this product.
* Precautions for installing the holder
• Adjust the position so that it is upright.
• Ensure that the screw heads are not protruding.
• DO NOT attach the holder on plaster wall
How to insert batteries
1. Detach the back lid.
2. Insert the batteries. (two AAA batteries)
3. Reattach the back lid.
Setting to avoid mixed communication
1. Detach the back lid, and remove the batteries.
2. Cut off the switching wire in the battery compartment using nippers.
3. Insert the batteries, and attach the back lid.
Changing the remote controller setting
How to change the Auto Run setting
The Auto Run mode is not available on the building air conditioning and gas heat
pump series (excluding the cooling/heating free multi system).
When using the remote controller to operate those models, set the remote controller
to disable the Auto Run mode.
To disable the Auto Run mode, press the
ACL
switch while holding down the
MODE
button, or insert batteries while holding down the
MODE
button.
* Note: Once the batteries are removed, the setting is reset to the factory default.
When the batteries are removed, repeat the steps described above.
Indoor function settings
1. How to set indoor functions
1
Press the ON/OFF button to stop the unit.
2
Press the desired one of the buttons shown item 2. while holding down the
FUNCTION SETTING switch.
3
Use the selection buttons
▲
and
▼
to change the setting.
4
Press the SET button.
The buzzer on the remote control signal receiver beeps twice, and the LED
lamp flashes four times at two-second intervals.
For the shop series
For VRF series, set the indoor unit address with SW1, SW2 and SW5-2 on the indoor unit PCB from [000]
to [127] so as not to duplicate.
For the building air conditioning and gas heat pump series
Set the indoor unit and outdoor unit numbers by manually specifying the addresses.
Use the rotary SW1 and SW2 provided on the indoor unit PCB (printed circuit board) to set the indoor unit
numbers so that they are not duplicated.
Master/Slave setting when using multiple remote controller
Up to two receivers can be installed in one indoor unit group.
Wireless remote controller’s operable area
1. Standard reachable area of the signal
[Condition] Illuminance at the receiver: 300lux
(When no lighting is installed within 1m of the receiver in an ordinary office)
2. Correlation between illuminance at the
receiver and reachable area of the signal
in a plain view.
The drawing in the right shows the
correlation between the reachable area of
the signal and illuminance
at the receiver when the remote
controller is operated at 1m high
under the condition of ceiling
height of 2.4m.
When the illuminance becomes double,
the area is narrowed down to two thirds.
3. Installation tips when several receivers are installed close to one another.
Minimum distance between the indoor units which can avoid cross communication is 5m under the
condition of 300lux of illuminance at the receiver.
(When no lighting is installed within 1m of the receiver in an ordinary office )
Backup switch
A backup switch is provided on the receiver section of the panel
surface.
When operation from the wireless remote control unit is not possible
(due to flat batteries, a mislaid unit, a unit failure), you can use it as an
emergency means. You should operate this switch manually.
1. If pressed while the air conditioner is in a halt, it will cause the air
conditioner to start operation in the automatic mode (In case of
cooling only, it is in the cooling mode).
Wind speed: Hi fan, Temperature setting: 23°C, Louver: horizontal
2. If pressed while the air conditioner is in operation, it will stop the air conditioner
Cooling test run operation
• After safety confirmation, turn on the power.
•
Transmit a cooling operation command with the wireless remote control unit, while the backup switch
on the receiver is pressed.
• If the backup switch on the receiver is pressed during a test run, it will end the test run.
• If you cannot operate the unit properly during a test run, please check wiring by consulting with
inspection guides.
How to read the two-digit display
On the receiver of a wireless kit, a two-digit (7-segment) display is provided.
1. An indication will be displayed for one hour after power on.
2. An indication will be displayed for 3.5 seconds after transmitting a “STOP” command from the
wireless remote controller or the operation of the backup switch to stop the unit.
3. An indication appearing in (1) or (2) above will go off as soon as the unit starts operation.
4. When there are no error records to indicate, addresses of all the connected units are displayed.
5. When there are some error records remaining, the error records are displayed.
6. Error records can be cleared by transmitting a “STOP” command from the wireless remote
controller, while the backup button is pressed.
