The unit booting sequence is similar to a personnal 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 AMBER for 10 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.
4.1.2 HRV160
During the booting sequence, the integrated control LED will light GREEN (unit set in normal defrost) or amber (unit set in
extended defrost) for 3 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.
