Lutron RR-PROC3: The RadioRA 3 All-in-One Processor, Explained

The Lutron RR-PROC3 is the brain of a RadioRA 3 lighting control system. If you're speccing or quoting RadioRA 3, the processor is the first part on the schedule. It sets how many devices the system can control, how far they can sit from the processor, and which existing Lutron gear you can carry over. This page covers exactly what the RR-PROC3 is and the numbers you design around it.

What is the RR-PROC3?

The RR-PROC3 is the RadioRA 3 All-in-One Processor, the central controller every RadioRA 3 system is built on. It talks wirelessly to the system's dimmers, switches, keypads, sensors, and shades, runs the programming (scenes, timeclock, schedules), and is the connection point for app and integration control.

You'll see it ordered two common ways:

• RR-PROC3-CW is the processor in a white finish, the standard stand-alone processor SKU.
• RR-PROC3-KIT is the RadioRA 3 all-in-one processor starter kit, which bundles the processor for a quick system start.

This guide covers the processor itself. For the bundled kit, see our separate RR-PROC3-KIT explainer.

How many devices does one RR-PROC3 control?

RadioRA 3 splits devices into two wireless families, and each has its own limit per processor:

• Clear Connect Type-X (CCX), the current Sunnata RF family: up to 100 CCX devices per processor. Sunnata companion dimmers and switches do not count toward this 100-device limit.
• Clear Connect Type-A (CCA), legacy RadioRA 2 / RA2 Select devices: up to 95 CCA devices per processor.

When a project outgrows one processor, RadioRA 3 scales by adding more. A system supports up to 4 processors, up to 200 CCX devices, and up to 190 CCA devices across those processors.

Repeaters: extending a RadioRA 3 system

For larger footprints, RadioRA 3 uses Auxiliary Repeaters to reach devices farther from the processor: up to 4 Auxiliary Repeaters per processor, and up to 8 per system.

One design note that trips people up: repeaters extend range for Clear Connect Type-A devices. Per Lutron, the wireless repeater does not extend the range of Clear Connect Type-X (Sunnata) devices. CCX relies on a mesh layout instead, covered next.

Range and layout rules you must design around

Lutron publishes hard range limits for a RadioRA 3 system. Get these wrong on paper and the system won't communicate reliably on site.

Clear Connect Type-X (CCX), wireless mesh:

• All CCX devices must be within 75 ft (22.9 m) of the processor.
• At least 2 CCX devices must be within 25 ft (7.6 m) of the processor.
• Each CCX device must be within 25 ft (7.6 m) of two other CCX devices.

Clear Connect Type-A (CCA):

• Each CCA device must be within 30 ft (9.1 m) of the processor or a repeater.
• Repeaters must be within 60 ft (18.2 m) of the processor or another repeater.

What the RR-PROC3 is compatible with

A big reason RadioRA 3 exists is backward compatibility. The RR-PROC3 works with current Sunnata RF (Clear Connect Type-X) devices and most existing RadioRA 2 / RA2 Select (Clear Connect Type-A) devices, so you can modernize a system without ripping everything out. Compatible controls include:

• Sunnata RF touch dimmers, switches, keypads, and fan controls
• Pico wireless remotes
• Maestro RF dimmers, switches, and fan controls
• seeTouch and seeTouch C·L hybrid keypads
• Radio Powr Savr occupancy/vacancy sensors
• Sivoia QS Wireless and Triathlon shades

A few older RadioRA 2 / RA2 Select devices are not compatible with RadioRA 3, including the GRAFIK Eye QS Wireless control unit, GRAFIK T and seeTemp keypads, TouchPRO Wireless temperature control, the Wallbox Power Module, and the HVAC controller with wireless temperature sensor. Confirm the device list before quoting a retrofit.

Where the RR-PROC3 fits

If you're choosing between Lutron platforms, the processor is what separates RadioRA 3 from the smaller systems. Caséta and RA2 Select top out far lower on device count and don't use a RadioRA 3 processor at all. For that comparison, see RadioRA 3 vs RadioRA 2 and RadioRA 3 vs Caséta.
