TIME TO GO AND DIAGNOSTIC DISPLAY FOR ELECTRONIC SEQUENCE TYPE APPLIANCE CONTROLLER ABSTRACT OF THE DISCLOSURE An electronic sequence type controller for appliances or the like which provides numerical indications of how much time will be re- quired to execute a program cycle which a user has selected, and how much time is remaining as an operating cycle proceeds. Additionally, means are provided for a service technician to rapidly set the controller to a particular program step for diagnostic purposes. More specifically, after user cycle options have been inputted, control logic initially enables a counting and display means to count up and rapidly executes the entire selected program a first time, the rapid first execution appear- ing essentially instantaneous to the user. This presets the counting and display means with a representation of the total number of program advancing operations required to execute the selected program. Next, the control logic means enables the counting and display means to count down, and executes the selected program a second time with relatively longer intervals between successive program advancing operations. The counting and display means then provides a continuous representation of the remaining time to go during the second execution. For diagnostic purposes, the control logic has a diagnostic mode wherein the program is advanced incrementally a step at a time in response to manual actua- tion of a switch.
