I bought 2 of these controls. The package and the instructions both say that it is a dimmer and will work on CFL bulbs. I bought dimmable CFL bulbs but it does not dim. Also, the instructions explain how to "pair" the control with the receiver but it doesn't work. One control controls one room and the other control controls both rooms. I called their tech support and they said it should work. Does anyone know how to fix either of these problems? Thanks for any help you can give me.
