EQUENCE
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 or AMBER 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.

PTIONAL
For more convenience, these units can also be controlled using an optional main control.
Only one main control can be connected per unit.
NOTES: 1. The integrated control must be turned OFF to use an optional main control.
2. If an optional auxiliary control is used, its activation will override the main
control operation.
For more information about your unit controls, refer to the Main and auxiliary wall controls
user guide (included with your unit and also available at www.broan,com).

Risk of electric shock. Before performing any maintenance or servicing, always
