Test Operation

Implementing a Test Run

1. Turn the #1 DIP switch of the operation panel from OFF to ON (Down

→

Up) and operate the wireless remote

controller with its Start/Stop button.

2. During a test run, all display lamps on the display will light up.

3. During a test run, it is not possible to adjust the temperature.

4. After completing a test run, be absolutely sure to turn the #1 DIP switch from ON to OFF (Up

→

Down) and

make sure none of the display lamps are blinking. Also, replace the PCB cover back as it was and fasten it;

while holding the wiring in the cable clamp, tighten its screw.

DIP Switch Bit 1

<Note 1> This is hard on the device, so only use this for the test run.

<Note 2> After turning on the power, the unit will not receive any commands from the remote controller for about 1

minute. This is not an error. (In fact it does receive signals, but they are cancelled.

Setting Address Switches



When more than one display/operation panel and remote controller are installed in the same room, setting up

addresses allows them to avoid interfering with each other.



Refer to the Operating Instructions for information on how to change the addresses of the remote controllers.

Common to All Models



The indoor unit and the wireless remote controller are equipped with

indoor temperature sensors. The sensing of indoor temperature works

via one of them.



When the unit is shipped, it is set to the indoor unit, but to switch to

the remote controller, press the sensor button (diagram at right) inside

the remote controller’s cover and then check to make sure that Main

Sensor on the LCD screen goes off.

<Note> Even when the sensor switch has been set to the remote

controller, if the unit does not receive any room temperature

data from the remote controller for ten minutes, it

automatically switches back to the indoor unit sensor, so be

sure to install the remote controller facing the receiver.

Setting Up Remote Control Functions

The functions of the wireless remote can be set on site.

(These settings are saved in nonvolatile memory in the remote controller, so even when its batteries are

changed, the settings do not revert to the defaults.)

<Note> The operation of the air conditioner can be impacted, depending on the settings made, so only service

personnel should make the settings.

Furthermore, making changes to these settings may cause actual operation to deviate from what is

printed in the Operating Instructions, so be sure to explain this to the customer fully.

Making Settings (Do with unit stopped.)

1. Holding down the Swing/Wind Direction + OFF Timer + Mode Select buttons at the same time for 4 or more

seconds makes the display switch to the setting screen. (See Diagram Below.)

2. Use the Temperature setting buttons,

/ , to select the number of the item to be set.

3. Use the ON Timer buttons,

/ , to change settings.

4. The settings are saved with the Once/Every Day button. When this is done, the settings display of the LCD

changes from blinking to light.

5. If other settings are to be changed as well, repeat steps 2 to 4.

6. When all settings have been made, press the Start/Stop button.

Example: Operation mode setting screen
