By pressing the "Mute" button the fan speeds will reduce
to minimize noise levels projected by the outdoor unit.
However, in "Mute" speed, the capacity will also be
decreased. Press once to turn on and once to turn off.
The "Boost" button will allow the user to increase
capacity by increasing the compressor speed. The
speed is influenced by modulating algorithim's internal
to the unit.
To change the current time settings on the indoor unit, press and hold the "clock" button for
3 seconds. Press the up or down arrow to adjust the hours. Press the "clock" button again
to adjust the current minutes. Once the correct time is adjusted, press the "M" key to save. If
there is no changes in 10 seconds the clock will time out and no adjustments will be saved.
