The " HT " error message means something is causing the unit to overheat. It stands for High Temperature. To clear this error message, make sure the unit is not covered by anything such as clothes or drapery if it is hung on the wall.

If the unit is being used on the floor, please make sure the feet are properly assembled on the unit.

If the feet are not properly assembled, the air cannot pass through the unit which will cause overheating.
