NOTE: The integrated control must be turned OFF to use an optional main control.
If a problem occurs during the unit operation, its integrated control LED (2) will blink. The color
of the blinking light depends on the type of error detected. Refer to Section 4 Troubleshooting
on last page for further details.
2.1 B
OOTING
The unit booting 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 defrost control LED will light 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.
2.2 O
PTIONAL
For more convenience, this unit can also be controlled using an optional main wall
control. Many models can be used, but only one main wall control can be connected to
the unit.
NOTES: 1. The integrated control must be turned OFF to use an optional main control.
2. If an optional auxiliary control is used, if activated, the operation of this
auxiliary control will override the optional main control operation.
For more information about the available controls and their operation modes, refer to the
Main and auxiliary wall control User Guide (included with the ventilation unit and also
available at www.broan.com).
