METHOD B: Installing a stand-alone Room Controller

You can install the RC642D Room Controller as a stand-alone unit, but not the RC642.

To mount the Room Controller

NOTE If needed, the Room Controller has a secondary backplate that you can mount
behind it to cover certain junction boxes.

To wire for power

Pull the backplate off the Room Controller. If necessary, turn the setscrew in the
bottom of the Room Controller clockwise until you can remove the backplate.
Pull the power and input/output wiring through the rectangular opening in the
backplate (and the secondary backplate if you are using it).
Use screws to mount the backplate to a junction box. The holes in the backplate
accommodate most standard junction boxes.
After you connect the power (page 8) and input/output (page 13) wiring to the Room
Controller and select a control program (page 31), attach the cover and circuit board
to the mounted backplate.
Turn the setscrew one full turn counterclockwise so that the cover cannot be
removed.
The Room Controller is powered by a Class 2 power source. Take appropriate
isolation measures when mounting it in a control panel where non-Class 2 circuits are
present.
ALC controllers can share a power supply as long as you:
○
Maintain the same polarity.
○ Use the power supply only for ALC controllers.
Remove power from the Room Controller.
Unplug the Comm/24 Vac screw terminal connector from the back of the Room
Controller.
