Abnormalities of Devices
Check Item
Check the "Check Mode 1:
q1" on the wired controller.
↓
Check if there is motion
sensor with "Reaction rate
always 100%".
Operate under detection
area of motion sensor and
check the "Check Mode 1:
q1" on the wired controller.
↓
Check if there are motion
sensors with "Reaction
rate always 0%".
Check setting on the wired
controller.
Check setting on the wired
controller.
Check heat source
(a moving object whose
temperature is different
from surroundings).
Stop the operation from the
wired controller, no motion
in the detection area of the
motion sensor and check
the "Check Mode 1: q1".
↓
Check if there is no motion
sensor with "Reaction rate
0%".
Check the louver operation
after no one has been in
the room for more than 15
minutes.
Check heat source
(a moving object whose
temperature is different
from surroundings).
TROUBLESHOOTING
Action
(Turn OFF Main Switch)
True: Replace motion
and radiation sensors
PCB.
False: Replace control
PCB.
True: Replace motion
and radiation sensors
PCB.
False: Sensitivity may
be low. Adjust the
[Optional Function: K6]
to [01: High Sensitivity]
and see if there are any
changes. If the symptom
continues, replace
motion and radiation
sensors PCB.
Correct the setting.
Correct the setting.
Remove it.
True: Replace motion
and radiation sensors
PCB.
False: No problem.
Adjust the [Optional
Function: K6] to [02: Low
Sensitivity] and see if
there are any changes. If
the symptom continues,
replace motion and
radiation sensors PCB.
Not operating in "Avoid
Air" or "Receive". This is
normal operation.
Remove it.
Replace motion and
radiation sensors PCB.
