The present invention provides a method of programming a preset intensity of a dimmer switch from a radio-frequency (RF) remote control. A user is able to adjust the intensity of the lighting load to a new intensity and subsequently press and hold a preset button on the remote control to program the new intensity as the preset intensity. The remote control transmits a wireless transmission to the dimmer switch, which immediately responds to the actuation of the preset button by controlling the intensity of the lighting load to an old preset intensity. The dimmer switch then blinks a light-emitting diode representative of the new intensity to provide feedback that the dimmer switch is in the process of programming the preset intensity to the new intensity. Eventually, the dimmer switch stores the new intensity as the preset intensity and stops blinking the light-emitting diode.

The present invention provides a method of programming a preset intensity of a dimmer switch from a radio-frequency (RF) remote control. A user is able to adjust the intensity of the lighting load to a new intensity and subsequently press and hold a preset button on the remote control to program the new intensity as the preset intensity. The remote control transmits a wireless transmission to the dimmer switch, which immediately responds to the actuation of the preset button by controlling the intensity of the lighting load to an initial preset intensity.
