That was uncalled for. We didn't misinterpret your question at all. That is the correct method. And this is the explanation:
The results of this "laziness, incompetence and negligence" can be breathtaking:

I've long maintained that in many cases, fuel suppliers doing boiler or furnace service is a conflict of interest. What motivation do they have to make your system run efficiently, if it means they make less money on fuel?

For anyone tired of technology, here is a picture of my old low-tech boiler.
Re: Barcalounger Job
Rh and W gives me what I need, i.e. an end switch closure. Also, this is what Honeywell recommended.
But what I'm realizing is that it's not a dry contact. It took me awhile to figure out what I had done wrong:
I had wired Rh and W to the T-T terminals on the Taco zone valve control. I've always wired the T-T terminals to an isolated end switch, be it a thermostat or a dry contact. Polarity doesn't matter. But here, I had wired the W terminal on the Taco ZVC to the R terminal on the Honeywell EIM so that the W terminal was picking up a closure signal even when there was no call for heat.
@Mustangman hit the nail on the head, but I had to figure it out on my own. Thank you!

Sometimes you gotta break a few eggs to make an omelet. This will get resolved and HeatingHelp will be even better than it was before.
The old editor was not great. The new editor is better, just one minor bug.
Years ago I was a project manager in information technology. Software upgrades were always an adventure.
Re: New York gas piping
I was surprised years ago when I read on the Rectorseal True Blue can to "dope the inside threads on pipe 1 1/4" and larger" but that is what they say.
I will just show the can to the inspector and tell him "I put dope on according to the MFG instructions"😎
Re: Pickup Factor in older buildings
I really appreciate all the good input and advise provided here. Going to have to make a call on those 3 column radiators once I am up there and get good measurements this summer. Still going to be a slight guessing game on the edr unless someone has further insight or any epiphanies on them. At least it seems we have held off the boiler purchase now until then so that is a success. Just needs to be ready to go before the coming winter.
Re: Rest in Peace
@Mustangman and @LRCCBJ, I'm sorry you both lost close friends this month, especially so suddenly. I know firsthand how tough that is. Thanks for sharing your memories of them with us.
And @Mustangman, your back injury sounds painful and frustrating. I'm sorry you're going through that. I'm glad you're surrounded by loved ones at home and friends here to help you through.
