    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.

    Hey, but it had a "rain switch". Good stuff, way before my time. What made you think of this goody?

    Superior used to offer one with three concentric dials that were red, yellow and blue.

    They all had the concentric dials - part of the basic Intermatic mechanism. Superior sold a modified version that also included individual zone switches for Auto-Off-Manual operation of the zones.

    This was about as inexpensive as a reliable controller got.
    I occasionally look to see what bits of irrigation 'history' are being auctioned.

    I can remember walking into garages & seeing those Intermatics,
    every time my blood ran cold..glad they're gone (mostly).

    One very nice thing about those old Intermatics was the unlikelihood of the homeowner ever trying to reprogram it.

    Iv'e seen one of those, that looks just like brand new! (lives in a dark basement) It's branded Rain Bird though. I don't even *try* to change any of the program. it runs like 3 days a week, whenever it feels like. Customer has no desire to change it either.

    You can start it manually by pressing the manual tab 3 or 4 times till it makes a good "clank" sound. *as per the instruction on this model*

    Well, put on your goggles, cuz here we go!

    The Superior 503 with individual zone switches


    cover plate removed - note the arrow on the panel


    "MANUAL REGENERATION"?? ~ that means this thing is really a modified water softerner clock!! How undignified. almost as undignified as that little panel with the 3 zone switches, which was epoxy-glued (and none too neatly) to the output terminal block
