Installation Instructions
After wiring, the C202 should be screwed to your backbox using either the screws from your old switch or the supplied screws.
To install the C202N into a faceplate:
- Put the dimming stalk and base through the hole in the faceplate.
- Place the washer and nut over the dimmer stalk, in that order.
- Tighten the nut until the C202N is secured firmly to the faceplate.
- Align the D-shaped slot on the back of your dimmer knob with the dimming stalk, then push it into place.
Factory Reset the Device
Turn on the light, then perform 4 short presses followed immediately by holding a long 5th press (3 seconds) on the knob.
Confirmation: Once reset successfully, the connected light will flash 5 times.
