The examples shown here are for educational purposes only. Actual wire colors and connection methods may differ from what is shown here. Consult the product's installation instructions for full details.
NOTE: If the incoming 120 V~ power is run directly to the fixture, a wired keypad will NOT work and you must use the Pico remote control option.
How to Use a Single-Pole, Hybrid Keypad in a 3-Way Application (using a Pico Remote Control)
The hybrid keypad acts like a single-pole dimmer/keypad and a Pico remote control is added to the other 3-way location without being connected to the wiring.
| Incoming 120 V~ power and outgoing lighting load connections are in the same 3-way location: | Incoming 120 V~ power is at one 3-way location and the outgoing lighting load connection is at the other 3-way location: | |

How to Use a Single-Pole, Hybrid Keypad in a 3-Way Application (using a Dimmer)
The hybrid keypad is rewired to act like a standard keypad (the internal dimmer is not used) and a dimmer is used in the other 3-way location.
NOTE: This solution is NOT recommended. The hybrid keypad will appear as a lighting load in the Lutron App or third-party integration despite the device acting only as a keypad and not controlling the actual load in this application. This could cause confusion for the end user.

How to Use a Single-Pole, Hybrid Keypad in a 3-Way Application (using a -W Keypad)
The hybrid keypad acts like a single-pole dimmer/keypad and power is run to the other 3-way location to operate a standard keypad.
