What IS THIS???

Steamhead

many of us have never seen one of these things! I'm sure the Dead Men who designed and installed that system are smiling down on you........

B&G Comfort Control Regulator Cat#72

I was on a job for something unrelated to this item but as a favorite speaker I know is found of saying there is more in the basement then just the boiler. So i was wandering and following pipes while the system ran up to tempature and :::sidenote-This is a 12 family unit with monoflo piping to the units:::: while following a main to see where it went I found an odd fitting piped in. It was a 90 degree fitting in a monoflo take off that had 2 1/8" tappings that were piped into this B&G control mounted approx 8' away up in the floor joists of the ceiling. The B&G comfort control regulator. Well it also was wired up with line voltage which was still live.
Its hard without a picture or diagram but let me see if I can describe it better.
Off of the main to a monoflo tee to this 90...then out the other side of the 90 to continue on its normal monoflo way then back to the return main via a return monoflo tee into the return. It gets strange at the 90 i mentioned. that has 2 1/8" lines coming out of it to this B&G control. I can only assume it regulates the flo through this monoflo circut in some way I dont understand as the odd 90 fitting is just a fitting...not a valve...
I am going to try to figure out a way to link a pic and diagram but for now thats all I can say about it as access to the living space was not available and i only got to look at this from the basement.

I did narrow the patent number to the year 1954 or 55.

It's an early outdoor-reset controller

Here's how it fit into the system. This diagram shows a boiler with a bypass, but the Regulator could also be used to control the burner directly. In that case, the Comfort Control Valve and bypass were not used. Info from 1954 B&G Handbook.

The Handbook also has wiring diagrams. Tell me which controls are still there and I'll post the one you need.

Outstanding..Thank you...

Incredible....not only an answer but a picture as well...
I am going to slate some time to go back there and look further now because about 4 years ago the boiler was changed by a contractor and although the control is powered I am very very curious as to how it is wired in....
Thanks a ton for the info and I will post back what I find.
