Once the wall control connections have been made, insert the terminal connector in the electrical compartment.
NOTE : For information about the operation of the wall control, refer to the corresponding Installation and User Guide, available at
www.Broan-NuTone.com.
Always disconnect the unit before making any connections. Failure to cut power could result in electrical shock or damage
to the wall control or electronic module inside the unit.
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 the risk
of electrical interference (noise), 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.
