Lutron MACL-153M Dimmer Details
The Lutron MACL-153M belongs to the Maestro family and carries Lutron's C•L and LED+ branding. It is built to dim modern LED and CFL bulbs and also handles traditional incandescent and halogen lamps. One device works for a single-location switch or as the master unit in multi-location circuits. That makes it a sensible replacement for an ordinary toggle switch in most homes.
Operation runs through one large tapswitch and a pair of raise and lower buttons. When the lights are off, a single tap brings them back to the last preset level. A double tap jumps straight to full brightness. When the lights are on, a single tap turns them off, while pressing and holding the tapswitch starts a delayed fade-to-off. That gives you time to leave the room before it goes dark. A vertical row of indicator lights shows the current light level.
A key feature is the adjustable low-end trim for LEDs and CFLs. To set it, hold the tapswitch and the lower button until an indicator light blinks. Then lower the setting to the bottom position and use the raise button until every bulb in the room is on and stable without flickering. A single tap saves the setting. Lutron says this step is optional for incandescent and halogen loads.
Installation starts with turning off power at the circuit breaker, since the manual warns of a serious shock hazard. Wires can be fully wrapped around the screw terminals or pushed into the push-in terminals after stripping. In single-pole wiring, the two black wires are interchangeable. If you mount several devices side by side, you can bend the side sections back and forth to snap them off. Doing so lowers the incandescent rating, but LED loads are not derated.
For 3-way circuits with an existing mechanical switch, mark the common wire on both old switches before you remove them. Rewire the existing switch with the included jumper wire. Then reprogram the dimmer by holding the tapswitch and the raise button, selecting IL1 with the lower button and tapping to save. IL4 is the default setting for Maestro Companion Dimmers.
The FASS pull tab lets you cut power to the lamps safely when replacing a bulb. Lutron recommends checking its LED Finder and Compatible Bulb List, because flickering, buzzing or dropout usually means a bulb is not compatible. Keep the dimmer away from dust and dirt while painting or spackling. It is normal for the dimmer to feel warm during operation.
When there is no grounding means in the wallbox, code allows installation with a nonmetallic faceplate and fasteners, or on a GFCI-protected circuit. In either case, cap or remove the green wire before mounting. Do not use the dimmer to control receptacles, motor-driven appliances or transformer-supplied loads. Clean it only with a soft damp cloth.
