Lutron Caséta Programming Guide

• No-neutral vs neutral: the Caséta in-wall dimmer PD-6WCL is a no-neutral design. The PRO dimmer PD-10NXD has a white neutral lead — connect it if a neutral is available, otherwise cap it; Lutron requires the neutral for MLV loads and LED drivers. ^[1] The ELV+ dimmer PD-5NE and the neutral switches PD-5ANS/PD-6ANS require a neutral. ^[1]
• Line vs load: on Diva smart dimmers and Claro smart switches, the red wire must go to the load and black to line/hot — the device won't work if reversed (except in Pico-only 3-way setups with Diva, where Lutron says black and red are reversible). ^[1]
• Side sections: breaking off a dimmer's side fins for ganging reduces its maximum load rating — check the derating chart in the instructions. ^[1]
• Pico remotes are battery powered and need no wiring; mount with the Pico wall-mounting kit (PJ2-WALL) and Claro wallplate to replace a 3-way switch. ^[1]
• Smart Hub (formerly Smart Bridge, L-BDG2-WH; Smart Hub Pro L-BDGPRO2-WH) connects to the router by Ethernet — it does not join Wi-Fi. ^[3]
• Range: Lutron lists a 30 ft (9 m) operating range for Pico-to-device. ^[6]

1. Press and hold the Off button on the dimmer or switch for about 6 seconds until its LEDs start blinking.
2. Press and hold the Off button on the Pico for about 6 seconds until the lights flash 3 times.
3. Repeat for additional Picos. ^{[2] [7]}

Favorite level: set the light where you want it, then hold the round favorite button on the Pico about 6 seconds until the dimmer LEDs flash. ^[2]

1. Set up the Smart Hub in the Lutron app (create an account, plug the hub into a router LAN port).
2. In the app: open the menu (top-left) → Add Device → choose the device type → tap the device image.
3. Press and hold Off (or Close on shades) for about 10 seconds until the device's indicator LEDs blink quickly.
4. Pick the room and the light type, then add the next device or finish.
5. If the app doesn't advance after 30 seconds, factory reset the device and retry; move the hub within 30 ft if it still fails. ^[3]

With a hub, Picos are added through Add Device and assigned in the app instead of the button-pairing method. ^[2]

• Pico as the 3-way: install the Caséta device at one location, tie the travelers/tagged wires through per Lutron's diagram, and mount a Pico on a wall bracket at the other location; then pair it (section 2). This is the method for the PD-6WCL. ^[1]
• With the existing mechanical 3-way toggle: Lutron provides diagrams for the PD-5WS-DV switch, PD-10NXD PRO dimmer, PD-5ANS/6ANS neutral switches, DVRF-6L Diva and DVRF-5NS Claro with a mechanical toggle at the other location. Follow that model's diagram exactly. ^[1]
• Caséta uses Picos for additional locations; it does not use wired companion/accessory dimmers like some other Lutron lines.

• Low-end trim — PD-6WCL / PD-10NXD / PD-5NE: enter by pressing and holding On and Darker together about 6 seconds until a status LED flashes (the PD-5NE guide labels the buttons; the PD-6WCL/PD-10NXD pages show the same sequence). Hold Darker until the light stops dimming or turns off, then tap Brighter until the light is stable without flicker. Save by holding the same buttons until the status LED stops flashing. Verify: tap Off, then Brighter — if the light is off or flickers, repeat. ^[1]
• Low-end trim — Diva smart dimmer (DVRF-6L): pull the FASS (front service switch) out, press and hold Off, push the FASS back in while still holding Off, keep holding until the light bar flashes; release, adjust the slider to the desired low end, press Off to save. Low-end trim is also in the app. ^{[5] [1]}
• High-end trim uses a similar enter / adjust / save procedure on PD-6WCL, PD-10NXD, PD-5NE and PD-3PCL — follow the pictured steps on pages 91–97 of Lutron's Caséta Advanced Guide (P/N 0301710) for your model. ^[1]
• Phase (ELV+ PD-5NE): if the top or bottom three LEDs blink, the dimmer is detecting the wrong load type — change the phase per Lutron's change-phase instructions (casetawireless.com/change_phase). ^[6]
• Plug-in lamp dimmer (PD-3PCL) as a switch: hold On and Off about 6 seconds until the indicator flashes; repeat to return to dimmer mode (lighting loads only). ^[1]
• Fan control (PD-FSQN), LED behavior and other advanced settings (fade, LED, scenes) are set in the Lutron app with a hub where the model supports them; options vary by model.

• Dimmers PD-6WCL / PD-10NXD / PD-5NE / PD-3PCL and Diva DVRF-6L: tap On quickly 3 times, holding on the third press; keep holding (about 3 s) until the light flashes quickly; release and immediately tap On 3 more times. The light flashes slowly 3 times then turns off; after reset it returns to full on. Trim settings are reset too. ^{[4] [1]}
• Switches PD-5WS-DV / PD-5ANS / PD-6ANS: tap On at least 3 times, holding on the last press, until the status LED flashes slowly; release and immediately tap On at least 3 more times. The status LED flashes quickly and the light flashes slowly twice; after reset the light turns on. ^[1]
• Fan control PD-FSQN: same tap-3-and-hold / tap-3 sequence on On; the status LED flashes slowly then quickly; after reset the fan runs on high. ^[1]
• Shades (roller / honeycomb): tap the Shade button at least 3 times holding on the last until its LED flashes green, release, tap 3+ more times; LED flashes green-then-red 3 times. Limits are kept. ^[1]
• After a reset, re-pair Picos or re-add the device in the app.

Other blink codes are model-specific — check the troubleshooting section of the model's own guide.
