Remote Controller Test Run Settings
1. Press the remote controller button for 4 seconds or longer. Then press the button.
● “TEST” 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 display.
(Refer to “7-6. Meaning of Alarm Messages” and correct the problem.)
4. After the test run is completed, press the button again. Check that “TEST” disappears from the remote con-
troller 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 ceil-
ing panel has not been installed. (“P09” display does not occur.)
Number changes to indicate which indoor unit is currently selected.
