OOTING

EQUENCE

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 GREEN for 5 seconds, and then will turn RED. 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.

5.3 S E
ETTING XTENDED
These units are factory set to normal defrost. In cold region (outdoor temperature -17°F and lower), it may be necessary to setup
extended defrost. During the first 2 seconds of booting sequence, while the integrated control LED is GREEN, press on push button
for 3 seconds to set the unit in extended defrost; the LED will blink AMBER to show the unit is in extended defrost mode. After that,
the LED will shut off, then light RED (the unit returns in its booting sequence).
