NEED HELP IDENTIFYING
I saw this on a system the other morning in a house that was built on the late 1900 in Cheltenham PA. The boiler is a Bryant 455, nat gas "tubular" boiler. This Dar-Gee Weather Compensator, from Glenside, PA is on the pipes. It appears as though wires were cut (top left of unit) and there is a brass dial on the bottom right.
Have you ever seen this???
Wow...
I didn't know such a thing existed and don't know that I can offer any help.
I am curious as to how it works though. Are there bolts holding the casing together around an assembley of sorts? I am wondering if there are some kind of bellows in it, much like that in Leonard mixing valves. The missing wires have me intrigued.
Looking forward to the REX show in Reno 2010.

New one on me, too
Looks like some sort of outdoor reset control. Is this a steam or hot-water system? Did you find any evidence of an outdoor sensor there?

the compensator
hey Paul & Steamhead,
The system is hot water. The supply and return are 1in which tells me it always hot water. Not like the 450,ooo BTU boiler sitting next to it with 6in mains and a common header and low returns suggesting that at one time it was steam.
The unit goes into the side of a fitting under an inch of asbestos. If the contractor that is my customer gets the job I will be retrieving the control from the house to take it apart and play.
It appears to be threaded in, no bolts, a screw in dial at the bottom. The back may come off but it was not in a location for me to climb around. It appears that the electronics broke the power to the gas valve.
The amazing thing is that the manufacture location, "Glenside, PA" is right wround the corner from the house the control was in. I can find NOTHING anywhere on the company OR the boiler.
