any maintenance or servicing, always
disconnect the unit from its power source.

Refer to table below to see how to operate the unit using its integrated 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 11 Troubleshooting
on last page for further details.
4.1.1 BOOT SEQUENCE
The unit boot sequence is similar to a personnal computer boot sequence. Each time the unit is plugged in 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, this unit can also be controlled using an optional main wall control.
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, this auxiliary control will override the optional main control.
4.2 ELECTRICAL CONNECTION TO OPTIONAL WALL CONTROLS
Use the terminal connector included in the installation kit to perform the electrical
connection for main and optional wall controls. Check if all wires are correctly inserted in
their corresponding holes in the terminal block. (A wire is correctly inserted when its
orange receptacle is lower than another one without wire. On picture beside, wire A is
correctly inserted, but not wire B.)
CAUTION
Never install more than one optional main wall control per unit. Make sure that the wires do not short-circuit between
themselves or by touching any other components on the wall control. Avoid poor wiring connections. To reduce
electrical interference (noise) potential, do not run wall control wiring next to control contactors or near light
dimming circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.
WARNING
Always disconnect the unit before making any connections. Failure in disconnecting power could result in
electrical shock or damage of the wall control or electronic module inside the unit.
