< Check of the Motion Sensor >
1. Perform the motion detection (waving a hand, etc) under the motion sensor of the selected
indoor unit for approximately 10 to 15 seconds.
2. Check the value of “q1” after 30 (*1) seconds from starting the motion detection at Item 1. The
detection information from the motion sensor against the motion detection is displayed a range
of 0% to 100%.
(*1): The communication cable between the indoor unit and the wired controller is on a 30 second cycle.
Timing for motion detection and the detected information display is shown below.
3. Check that the value of ³T is neither 0% nor 100%.
If the value displayed is 0% or 100%, repeat the procedure from Item 1. If the same value
reappears, it may be a malfunction of the motion sensor.
