Abstract: Electronic laundry machine controller apparatus for automatically synthesizing, in response to single operator program selections, complete laundry cycles or programs from laundry machine control instructions stored, independent of operator selection or control, within an electronically read memory. A read only memory is preprogrammed to store laundry machine control instructions and program synthesis instructions for compiling a large number of different laundry programs, each having laundering steps or operations preconfigured to satisfy the peculiar laundering requirements of a large number of different commercial and institutional users. Program variation select means presettable by the manufacturer or upon installation of the controller enables preselection for execution from the large number of possible laundry cycles, only those laundry machine cycles which best satisfy the user's specific laundering needs. A single user input stimulus to cycle select buttons initiates execution by the controller of a laundry cycle associated with that selection. Addressing and control circuits select and sequentially execute in timed sequence those instructions from memory which correspond to the selected laundry cycle. Each instruction when executed provides digital control signals to laundry machine function control apparatus for performing an identifiable step or operation of the selected program. Unused variations of laundry cycles remain as an integral part of the controller and can be rapidly activated in the event of a change in the user's laundering requirements, without physical alteration or addition to the controller, by simple manual switching of entries into the variation selection switching means.
