7-21. Preparing for the Test Run
7-21-1. Changing the room temperature sensor
Room temperature sensors are installed inside the indoor unit and the wireless remote controller.
Either room temperature sensor can be used.
When “Unit Sensor” is indicated on the wireless remote controller’s LCD, the indoor unit sensor is operating as the
room temperature sensor.
To change to the remote control sensor, open the remote control cover and press the SENSOR button once. The
“Unit Sensor” display disappears, and the remote control sensor becomes the room temperature sensor.
CAUTION
If the temperature data from the remote controller is not communicated to the indoor
unit for a period of 10 minutes when the remote control sensor is selected, the unit
automatically switches back to the indoor unit sensor.
Install the remote controller in a location where the signal can reliably be received by
the indoor unit.
7-21-2. Using the remote controller
Face the remote controller toward the receiver (indoor unit).
The maximum distance where the remote controller signal can be received is approximately 26 ft., however this
distance is only a guide. The actual distance may vary somewhat depending on battery capacity and other
conditions.
Make sure there are no obstructions which can block the signal between the remote controller and the receiver.
When the remote controller signal is received correctly, the indoor unit beeps.
(It beeps twice only when operation is started.)
Do not drop, throw, or wash the remote controller.
Do not place the remote controller in a location exposed to direct sunlight, or near a stove or similar appliance.
7-21-3. Test run
Using the controller
(1) Slide the main unit controller switch from “ON” to “TEST”.
(The outdoor unit will not operate for approximately 3 minutes after
the power is turned ON, or after operation is stopped.)
(2) All indicator lamps on the display blink while test run is in progress.
(3) Temperature control is not possible during the test run.
(4) If normal operation is not possible, the lamps on the display will indicate
the problem. Refer to “7-24. Diagnosis Table”.
(5) After the test run is completed, move the controller switch from “TEST” to “ON” and verify that the indicator lamps
stop blinking.
(A 60-minute automatic OFF timer function is included in order to prevent continuous test run.)

TEST
Do not use this setting at any time other than for the test run. Doing so will place an excessive load on
the system.
Test run is not possible if the power was turned ON when the controller switch was in the “TEST” position.
Leave the power ON and move the switch to “OFF,” then move the switch back to “TEST.”
