When the unit is turned off, in COOL, DRY, or AUTO (cool) modes, it will continue to run for about 10
minutes with low fan airflow. This is to aid in drying any condensation that has formed inside the unit to
prevent mildew growth. Do not restart the air conditioner until the unit is completely off.
Operation Mode Selection
For the unit to be controlled by the remote control and/or the smart phone app, connect the wireless
control module to the USB port located behind the front cover of the indoor unit.
While two or more indoor units are operating simultaneously, make sure the modes selected on each of
the units do not conflict with one another. The HEAT mode claims precedence over all of the other modes.
If the unit initially started to operate in HEAT mode, the other units can only operate in HEAT mode. For
example: If the unit initially started to operate under COOL or FAN mode, the other units can operate
under any mode except HEAT. If HEAT mode is selected on one of the units, the other units will cease
operating, and one of the following will occur, depending on the model:
For models equipped with a display window only- This “--” will appear in the display window.
For units without a display window- The auto and operation indication light will flash rapidly, the
defrost indication light will turn off, and the timer indication light will remain on.
