For more convenience, these units 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.
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.
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.
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 at right, wire A is correctly inserted, but wire B is
not.)
