You can install the RC642D Room Controller as a stand-alone unit, but not the RC642.
NOTE
If needed, the Room Controller has a secondary backplate that you can mount
behind it to cover certain junction boxes.
1
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.
2
Pull the power and input/output wiring through the rectangular opening in the
backplate (and the secondary backplate if you are using it).
3
Use screws to mount the backplate to a junction box. The holes in the backplate
accommodate most standard junction boxes.
4
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.
5
Turn the setscrew one full turn counterclockwise so that the cover cannot be
removed.
CAUTIONS
•
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.
1
