Test run

* It may take approx. 10 minutes for local remote controller operation to be enabled after the power is turned ON. In this case, press the

ON/OFF button on the controller to enable immediate local remote controller operation.

(Test run procedure)

1. Turn ON the Power to the controller and all the units.

2. When the “INITIAL SETTING (PLEASE WAIT)” blink on the controller LCD stops, press the “

 ON/OFF switch” and the “tempera-

ture setting switcth  

” at the same time.

3. Confirm the run state (indoor unit outlet air temperature, cool air, confirmation, etc.) during the test run.

4. When each unit has been confirmed, stop the unit with the controller or local remote controller. Even if the units are not stopped, the

test run will stop automatically after approx. 2 hours.

* Refer to the installation manual for the connected indoor unit for details on the test run method.
