operation can be selected from “Running”, “Stand-by” or “Stop”
on the remote control switch.
(The default setting is “Running”.)
• Running:
The operation is continued with saving the capacity after
detected as an absence.
If the human activity is detected for a period of time, the
normal operation will be performed again.
• Stand-by:
The operation mode is the fan operation at “Slo” speed.
If the human activity is detected for a period of time, the
normal operation will be performed again.
• Stop:
The operation is stopped by the remote control switch when
all the indoor units with motion sensor detect absence which
are connected with same remote control switch.
If the human activity is detected for a period of time by the
stoppage, the normal operation is performed again.

interval time, the function “If absent” will be executed. The
interval can be selected from 30, 60, 90 120 or 180 minutes.
