URC Lighting: LT-3300 3-Way & 4-Way Connection Examples
The URC LT-3300 Configurable Dimmer or Switch is software configurable to be used as either a dimmer or a switch.
When a lighting device or lighting load is controlled from multiple locations, this is usually called a 3-way circuit. Traditional "dumb" 3-way light switches use an extra wire usually referred to as a "traveler" for a 3-way circuit. The URC LT-3300 does not a traveler. It uses additional LT-3300's and is "associated" to the main lighting load controller via the software using the Z-Wave network. Additional devices are usually referred to as a 4-way circuit.
Using the Accelerator software, you can associate up to 10 additional LT-3300's for up to an 11-way, muti-location control scenario.
There are two different "3-way" and two different "4-way" connection examples that are detailed in this article.
Note: URC recommends using a licensed electrician for any high-voltage device installations!

*Please note:
When using the LT-3300, you can associate up to 10 additional LT-3300's for up to an 11-way, muti-location control configuration.
When using the LT-3100 & LT-3200, you can associate up to 4 additional devices for up to an 5-way, muti-location control configuration.
