I would like to replace an older wall fan(3 speed)/light (On/Off) switch with a Lutron SFSQ-LF. My fan is a NuTone Scovill PFM52.The fan itself has 2 pull chains (1) for speed control(always on highest speed); (2) light on/off -again always on. Believe these are set this way so the wall switches will operate correctly.The wall switch is a NuTone Scovill PFSWL-52 -believe it has a transformer.The controls at the fan also appear to have a transformer, and some other module(capacitor?).Will the SFSQ-LF do the job on/off for the light and Off-Low-Med-High fan speeds?Any thoughts? need more information?
