Detection Method
•
The sensor detects human motion by receiving infrared rays and displays the pulse wave
output.
•
The microcomputer in the indoor unit carries out a sampling every 20 msec. and if it detects
55 cycles of the wave in 3 seconds in total, it judges humans are in the room as the motion
signal is ON.
•
The sensor may detect human motion with up to 20 msec latency.
Ex. Cooling
∗
In FAN operation, the fan speed is reduced by 100 rpm.
•
When the microcomputer does not have a signal from the sensor in 20 minutes, it judges
that nobody is in the room and operates the unit at a temperature shifted from the target
temperature. (Cooling: 1 ~ 2°C higher, Heating: 2°C lower.)
Note
For dry operation, you cannot set the temperature with a remote controller, but the target
temperature is shifted internally.
1.9.2 AUTO OFF Operation
•
When the INTELLIGENT EYE sensor judges that there is no one in the room, the set
temperature is shifted by +2°C in COOLING / –2°C in HEATING operation. When the set
time elapses with no change in the condition, the air conditioner automatically stops the
operation.
•
If
INTELLIGENT EYE
is off and
AUTO OFF
is on, the operation stops after the set period of
time.
