20 Most Recent AMS Lutron S2-LFSQ Skylark Dual Slide-to-Off Fan Speed Control and Dimmer 2 in Questions & Answers

You need to run another (separate) wire from the ceiling fan/light to the wall box, so you can wire one slider to the light, and one to the fan.

Sorry, its not something you can do from the wall-control. Unless the fan had a an embedded/built-in control module, the fan manufacturer's rarely make the "reverse" setting available from the wall control.

The only obvious idea I can think of is that someone swapped the light bulbs out for a different kind (replaced an incandescent with a non-dimmable compact fluorescent).

If it isn't directly related to the light bulb, then I would call Lutron's tech support number to help them diagnose. They're at 1-800-523-9466 and are available 24/7.

Call Lutron's tech support center directly at 1-800-523-9466. They're available 24/7 andif you're just looking for a knob or part of the knob, they'll probably just send it to you.

Yeah, it matters.

The first thing is that the fan-speed in that control is only rated for 1.5-Amps. The issue with bathroom fans (I have to assume an exhaust fan) is not only how much current they pull during normal operation, but what happens if the fan rotor locks - that can pull some pretty hefty current slugs that the device is NOT rated for.

Also, generally speaking, putting fan-control on an exhaust fan doesn't work that well. If you slow down the speed at all, it significantly minimizes the amount of air-flow going through the room - which means you're using all of that energy for basically nothing.

My recommendation is to instead get Lutron's MA-L3T251- device. Here, you have the dimmer for the lights (same as the control you bought), and you have a timer switch that's rated for general purpose fan loads (up to 2.5A).

Lutron S2-LFSQ is made to control one ceiling paddle fan & 1 light. Switch will not work on florescent lights.
See manual

To use this product, your fan and light must already be controlled by 2 separate switches.

If you have just one switch that turns on the light & fan together, the S2-LFSQ will not work (without additional wiring).

Okay, you have two switches. One switch turns fan on-and-off. The other switch turns light on-and-off.

Here is wiring diagram from manual: See diagram larger


Here's how to wire:
-Before disconnecting wires from existing switches, mark each wire with tape and pen.
-There is one wire that feeds power to both switches > mark this the 'Hot wire' and it connects to Lutron black wire (if you are unsure about this wire, remove switches, separate wires, turn on power and test each wire to bare ground, tape tester leads to wood sticks so hands are away from power, Tester lights up on Hot wire)
-The switch that controls fan > mark this the 'Fan wire' and it will connect to Lutron Yellow wire
-the switch that controls light > mark this the 'light wire' and it will connect to Lutron Red wire
-Lutron Green wire or bare wire connects to bare ground wire.

You will have power coming in through a black wire and white wire on the cable set that does not go out to your fan. The black will connect to your switch to power it. Then there will be two other terminals on your switch one for your fan and one for your light. The red and black that go out to your fan and light are connected to these two terminals. The whites get connected together. If you mix the red and black up and the switches are controlling the the wrong things, simply switch the black and red wires. (Note: If by three wires to your fan you meant black, white and bare copper this dual switch cannot be used, as bare copper is simply a ground wire and cannot be used as a constant electrical conductor.)

No, the way the motor speed control works is different from the way a light dims. If you connect it, it might work for a while, but it will either burn up the dimmer or the fan motor.

AMS Lutron... | Answered on May 22, 2010

This is simply a "switch" or think maybe a gate. It is either open or closed. Power can flow through or not.

It does not matter where the 2 (probably black) wires go, just that the ground is on the ground lug.

AMS Lutron... | Answered on Nov 04, 2009

Yes, it sounds like your input power wire got mixed up with one of the output wires.

AMS Lutron... | Answered on Sep 25, 2009

The old switch is just a single pole switch. The new one is for fan speed control. You need to use a regular single pole switch like you had. Or you can use a single pole switch on the Lutron you bought if you can figure out which wires to use. Do you have a meter?

Good question. What is the device?

Electrical... | Answered 12 hours ago

Not 100% sure but I suspect the LED replacements exhibit a significantly higher impedance when off, unlike incandescent and halogen.

If you have multiple cans controlled by one switch, try changing all but one to LED and likely there will be no flicker at the lighted switch.

If you leave at least one halogen on the circuit and it still flickers, be sure to comment here and I'll research further.

Load it the light, fan, motor, etc that consumes power

Typically, 120 volt incoming hot line is connected to black, white to neutral, ground to green...
Then load has 2 wires + ground ... the white connects to neutral, black connects to load wire, and ground to ground
