Silence
Press SILENCE on the remote controller to enable the SILENCE
function. While this function is active, the indoor unit runs at faint
breeze (1% fan speed), which reduces noise to the lowest possible
level.
Occupancy Sensor (Sizes 09K-12K)
With the built-in infrared sensor, the indoor unit detects human
movement. The compressor operates in a low frequency if you leave
the room for 30 minutes. The compressor operates in a lower
frequency if you leave the room for 120 minutes, and resumes
automatically when you come back, which helps save energy.
