Preheating
In order to prevent cool air blowing, 2-5 minutes
are necessary to preheat the indoor unit at
HEATING operation start. The indoor fan will not
work during preheating.

(de-ice) automatically to raise efficiency. This
procedure usually lasts 6-10 minutes. During
defrosting, fan stops running and running indicator
flashes. After defrosting is completeed, it returns

outdoor unit, outdoor unit can only run with same
mode (cooling or heating), so when the mode you
set is different from the mode that the outdoor is
running with, mode interfere occurs. Following
shows the mode interfere scene.
