The unit boot 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 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 is 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.

For more convenience, these units 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 auxiliary control operation 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
