The Lutron Maestro LED+ dimmer offers a means of controlling lighting from multiple locations. Installation procedures vary depending on the existing switch configuration—specifically, whether a mechanical switch or a Lutron companion dimmer is used in conjunction with the Maestro LED+ dimmer. The documentation details considerations for 3-way and 4-way installations, emphasizing the importance of proper wiring and, in some cases, dimmer reprogramming. This article provides a comprehensive overview of installation guidelines based on available documentation.
Identifying Model Numbers
Locating the model number is crucial for accessing specific support resources. According to Lutron documentation, the model number is typically found on the product packaging. If the original packaging is available, the number is located on the insert card (for clamshell packaging) or on the top of the box. If the packaging is unavailable, the model number is printed on a label affixed to the side of the dimmer or switch. Model numbers are generally 12-16 characters long and begin with a combination of letters followed by a dash.
Before You Begin: Required Tools and Components
Prior to installation, it is necessary to gather the appropriate tools. The Lutron documentation lists the following items as required: a Maestro LED+ Dimmer, a flathead screwdriver, a Phillips-head screwdriver, and pliers. In a 3-way installation, a mechanical switch can be used in place of a Maestro Companion Dimmer, provided it is rewired and the dimmer is reprogrammed accordingly. It is important to note that only one Maestro LED+ dimmer can be installed on a single lighting circuit. Additional control locations require the use of Maestro Companion Dimmers or, in specific 3-way configurations, a mechanical switch.
3-Way Installation Scenarios
The installation process for a 3-way dimmer setup differs based on the components used at each switch location. Three primary scenarios are outlined in the documentation:
- Maestro LED+ Dimmer with a Maestro Companion Dimmer: The Maestro LED+ dimmer can be installed at either the line-side or load-side electrical box when paired with a Maestro MA-R, MA-RR, or MSC-AD companion dimmer.
- Maestro LED+ Dimmer with a Mechanical Switch: The Maestro LED+ dimmer can be installed at either electrical wallbox when used with a mechanical switch. However, the mechanical switch must be rewired using the included yellow jumper wire, and the dimmer must be reprogrammed for proper functionality.
- Two Maestro LED+ Dimmers: The documentation explicitly states that only one Maestro LED+ dimmer can be installed on a single lighting circuit.
4-Way Installation Considerations
For 4-way installations, the Maestro LED+ dimmer can be installed in any wallbox, but only when used in conjunction with Maestro companion dimmers. The dimmer will not function correctly if installed in a 4-way circuit with mechanical switches.
Wiring and Reprogramming with a Mechanical Switch
When a Maestro LED+ dimmer is installed alongside a mechanical 3-way switch, specific steps are required to ensure proper operation. The existing mechanical switch must be rewired using the provided yellow jumper wire. Furthermore, the dimmer must be reprogrammed for use with a mechanical switch. Detailed instructions for this reprogramming process are available via a link provided in the documentation. Failure to rewire the switch and reprogram the dimmer will result in improper functionality.
Multiple Dimmer Limitations
The documentation consistently emphasizes that only one Maestro LED+ dimmer can be installed on a single lighting circuit. To achieve control from multiple locations, users must utilize Maestro companion dimmers for 3-way and 4-way installations or a single 3-way mechanical switch (with the aforementioned rewiring and reprogramming). Attempting to install multiple MACL-153M dimmers on the same circuit is not supported.
Safety Precautions
A prominent warning in the documentation highlights a shock hazard. Users are instructed to turn off the power at the circuit breaker or fuse before beginning any installation work. This precaution is essential to prevent serious injury or death.
Finding Installation Resources
Lutron provides a variety of resources to assist with installation. The “Wiring Wizard” tool, accessible online, offers installation videos, wiring diagrams, and step-by-step instructions tailored to the specific type of dimmer, switch, or sensor being installed. The documentation also directs users to FAQs and other support materials available on the Lutron website.
Product Compatibility
The documentation lists several types of switches and dimmers with which the Maestro system is compatible, including:
- 0-10V
- Electronic Low Voltage
- Fluorescent / LED 3-Wire
- Fluorescent 2-Wire
- Hi-Lume LED 2-Wire
- Incandescent / Halogen
- LED / CFL
- Magnetic Low Voltage
Conclusion
The Lutron Maestro LED+ dimmer provides a flexible solution for multi-location lighting control. Successful installation hinges on understanding the different configuration options—specifically, whether a companion dimmer or a mechanical switch is used—and adhering to the corresponding wiring and reprogramming instructions. Prioritizing safety by disconnecting power before installation is paramount. The Lutron website offers a range of support resources, including the Wiring Wizard tool, to guide users through the process. The documentation clearly states the limitation of only one Maestro LED+ dimmer per circuit, necessitating the use of companion dimmers or a rewired mechanical switch for additional control points.
