5. TEST RUN
Request concerning recording the indoor/outdoor unit combination Nos.
After automatic address setting has been completed, be sure to record them for future reference.
List the outdoor main unit system address and the addresses of the indoor units in that system in an easily visible location (next
to the nameplate), using a permanent marking pen or similar means that cannot be abraded easily.
Example: (Outdoor) 1 - (Indoor) 1-1, 1-2, 1-3… (Outdoor) 2 - (Indoor) 2-1, 2-2, 2-3…
These numbers are necessary for later maintenance. Please be sure to indicate them.
Checking the indoor unit addresses
Use the remote controller to check the indoor unit address.
1. Press and hold the button and button for 4 seconds or longer (simple settings mode).
2. The address is displayed for the indoor unit that is connected to the remote controller.
(Only the address of the indoor unit that is connected to the remote controller can be checked.)
3. Press the button again to return to normal remote controller mode.
1. Press and hold the button and button for 4 seconds or longer (simple settings mode).
2. “ALL” is displayed on the remote controller.
3. Next, press the
button.
4. The address is displayed for 1 of the indoor units which is connected to the remote controller. Check that the fan of that
indoor unit starts and that air is discharged.
5. Press the button again and check the address of each indoor unit in sequence.
6. Press the button again to return to normal remote controller mode.
5. Remote Controller Test Run Settings
1. Press the remote controller button for 4 seconds or longer. Then press the button.
“TEST RUN” appears on the LCD display while the test run is in progress.
The temperature cannot be adjusted when in Test Run mode.
(This mode places a heavy load on the machines. Therefore use it only when performing the test run.)
2. The test run can be performed using the HEAT, COOL, or FAN operation modes.
Note: The outdoor units will not operate for approximately 3 minutes after the power is turned ON and after operation is
stopped.
3. If correct operation is not possible, a code is displayed on the remote controller LCD display.
(Refer to “Table of Self-Diagnostic Functions” and correct the problem.)
4. After the test run is completed, press the button again. Check that “TEST RUN” disappears from the LCD display. (To
prevent continuous test runs, this remote controller includes a timer function that cancels the test run after 60 minutes.)
* If the test run is performed using the wired remote controller, operation is possible even if the cassette-type ceiling panel has
not been installed. (“P09” display does not occur.)
Number changes to indicate which indoor unit is currently selected.
