Abstract:
1. A programmable control for an appliance, the appliance responding to one of a plurality of transmission schemes, the programmable control comprising: a transmitter operative to transmit a radio frequency activation signal based on any of the plurality of transmission schemes; a user programming input; and control logic in communication with the transmitter and the user programming input, the control logic implementing a rolling code programming mode, a fixed code programming mode, and an operating mode, the control logic in rolling code programming mode generating and transmitting a sequence of rolling code activation signals until user input indicates a successful rolling code transmission scheme, the control logic in fixed code programming mode receiving a fixed code from the user programming input then generating and transmitting a sequence of fixed code activation signals until user input indicates a successful fixed code transmission scheme, the control logic pausing for a preset amount of time between the transmission of each activation signal in at least one of the sequence of rolling code activation signals and the sequence of fixed code activation signals, the preset amount of time sufficiently long to permit the user to respond and, if the user has not responded by the end of the preset amount of time, the control logic transmitting the next activation signal in the sequence of activations signals.
