MEMORY
The electronic control has a memory to retain all
functions and settings, as set up by the user, in the event
of a power failure. For example: once power is restored
to the unit, there is a two second delay before the fan
comes on and approximately three minutes delay before
the compressor is activated providing that the mode was
set for cooling and the set point temperature has not
been met in the room.

Automatic component protection
Your unit is equipped with Automatic Component Protection.
To protect the compressor of the unit, there is a three minute delay
if you turn the unit off or if power is interrupted. The fan will not be
affected. Also, if you switch from Cool mode to Fan Only mode, and
switch back to Cool mode, there is a three-minute delay before the
compressor comes back on.
