Well; it's a low voltage control device, ( I hope w/ those exposed wires ). Where those wires go and what it controls, ( cycle-mizes ), is necessary for you to come up w/ a good answer. Working w/ what you have, it must be some small mfgs. dream of how to save energy by cycling the power on and off incrementally rather than leave it on constantly. Probably saves nothing, but also probably sounds good when listening to the sales spew.

First thing I've ever googled that came up with nothing!

Yeah, me too. I tried all kinds of combinations, and nothing came up.

Re: CyclemizerThe value of experience is not in seeing much, but in seeing wisely.

The arizona corporation was formed in Arizona as "Enertrol Corporation" 10/3/1979 Arizona Corporate File Number -0125853-7
changed Name to "Ross Engineering Inc. in 1986.
Involuntary Dissolution/revoked with AZ SOS in 1994 regarding bounced check in 1993 for 1992 Annual Report Filing.
No patents I could find but did locate a long-deceased/expired trademark for the "Demand Manager". (EDIT: I see R.W. has found as well but using data mining source and not the Trademark office site).
Is this in your home?
Suspect it is a run time- or variable set-point- cycle-controller. (i.e. avoiding short cycling of equipment). May or may not be temperature or hygro compensated internal logic or externally interfaced (btwn thermostat, or moisture or humidity sensing device and run-equipment)
Likely interfaced with HVAC or environmental comfort equipment between thermostat and equipment (hp, ac, furnace, boiler, hot water, swamp cooler, elec resistance coil), or with water conditioning system, or with swamp cooler, or with irrigation equipment.
I would suspect therefore 1979 - 1982 vintage. Possibly containing a rudimentary IC and pot.
You'd have to trace the wiring, and look inside, to devine its true purpose and function (or ask the HO).
You might also search the Library of Congress.

During the late 70's and early 80's there was lot's of hype about damage to equipment caused by short cyling. So, I suspect H.G is right. Maybe should trace where exactly the wires go to see what it is supposed to be managing/protecting. The circuitry inside I would suspect is rudimentary as was said earlier: chip (maybe NE555), pot, and a few supporting components.

It needed a 5 volt or thereabouts power supply, and the power supply transformer would probably have been drawing current 24/7, further mitigating any benefit derived from the gizmo. I would advise ripping it all out.

Given the age of the device I would say it controlled a Disco Ball on the ceiling.
