The unit boot sequence is similar to a personal computer boot sequence. Each
time the unit is plugged after being unplugged, or after a power failure, the unit
will perform a 30-second booting sequence before starting to operate. During the
booting sequence, the integrated control LED will light Green (unit set in
normal defrost) or AMBER (unit set in extended defrost) for 5 seconds, and then
will shut off for 2 seconds. After that, the LED will light RED for the rest of the
booting sequence. During this RED light phase, the unit is checking and resetting
the motorized damper position. Once the motorized damper position completely
set, the RED light turns off and the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.
