Claim 2

An electronic remote control device for controlling timed functions of an appliance responsive to said control device, said control device having a processor for controlling operation of said control device, an input for entering command and time of command information for a function to be performed, a memory for storing the information entered at said input, a real time clock, comparing means for comparing time on said real time clock with the time of command information in said memory, actuator means for effecting a command signal to be communicated to said appliance when the time of command information for a particular command matches the time on said time clock, and a feedback pickup sensitive to output from the appliance for receiving both on/off and level of output information from the appliance indicative of whether a command signal from the control device has been successfully communicated thereto, said feedback pickup having means to indicate a failed command signal and said control device being responsive to such feedback pickup to re-enter commands when said filed command signal is indicated by said feedback pickup.

Claim 3

A remote control device as claimed in claim 1, wherein said feedback pickup is sensitive to audio frequency signals.

Claim 4

A remote control device as claimed in claim 2, further including an audio to digital convertor for converting audio frequency signals received at said feedback pickup to digital signals which are read by said processor.

Claim 5

An electronic control system for controlling timed functions of an appliance, said control system including a control device, said control device having a processor for controlling operation of said control device, an input for entering command and time of command information for a function to be performed, a memory for storing the information entered at said input, a real time clock, comparing means for comparing time on said real time clock with the time of command information in said memory, actuator means for effecting a command signal to be communicated to said appliance when the time of command information for a particular command matches the time on said real time clock and a feedback pickup sensitive to output from the appliance for receiving both on/off and level of output information from the appliance indicative of whether a command signal from the control device has been successfully communicated thereto, said feedback pickup having means to indicate a failed command signal, and said control device being responsive to said feedback pickup to re-enter commands when said failed command signal is indicated by said feedback pickup.

Claim 6

An electronic control system for controlling timed functions of an appliance, said control system including a control device, said control device having a processor for controlling operation of said control device, an input for entering command and time of command information for a function to be performed, a memory for storing the information entered at said input, a real time clock, comparing means for comparing time on said real time clock with the time of command information in said memory, actuator means for effecting a command signal to be communicated to said appliance when the time of command information for a particular command matches the time on said real time clock and a feedback pickup sensitive to output from the appliance for receiving both on/off and level of output information from the appliance indicative of whether a command signal from the control device has been successfully communicated thereto, said feedback pickup having means to indicate a failed command signal, and said control device being responsive to said feedback pickup to re-enter commands when said failed command signal is indicated by said feedback pickup.
