NIT 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 unit is checking and resetting the motorized damper position.
Once the motorized damper position completely set, the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.

ALL ONTROL S LECTRICAL
The VT9W wall control is the only main wall control compatible to your unit. Never attempt to install another wall
control model. Always disconnect the unit before making any connections. Failure to disconnect power could
result in electric shock or damage to the wall control or electronic module inside the unit.
Failure to comply with the following can cause erratic operation of the unit and/or the wall control:
Never install more than one VT9W 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.
Unplug the unit from power source. Open the side panel to access terminal blocks
(A is the one for main control connection only and B is the one for auxiliary controls). Pull
out from the unit board the needed connector(s).
Run the end of the control wire(s) through the grommet located on the unit wall. Refer to
illustration at right (side panel removed to ease understanding).
