Back in the day, most every company offered this three-zone controller in their catalog, as Intermatic would brand it as you desired. Fourteen-day calendar, 5-to-60 minute zone running times. One cycle per day, unless you obtained a special trip accessory (never saw one) The manual operation tab only engaged the cycling mechanism, and you would have to wait about 8 minutes before zone one clicked on. Fused overload protection, usually an inline fuseholder tucked behind the coverplate. Time of day adjusted by moving the black cover with the little window, made fast by the central screw. Start time was a lift-and-turn of the yellow dial, and changing the time of day would make it necessary to readjust the start time. Running times were adjustable by lifting and moving the spring-loaded stack of dials, one of which couldn't be reached until the coverplate was removed. And behind that coverplate was the real surprise, which will be revealed sometime in the near future. Richdel's version had a visible fuseholder that accepted a special bayonet-mount version of a standard glass fuse. I wonder if that part can be had these days.
