Was that with punch cards or patch cables?Jamie Hall said:Before someone wonders... I do also have a couple of university degrees... and served my country many years ago... but i got my PE license the old fashioned hard way, starting as a labourer... Not much heavy equipment, except cranes, I haven't operated at one time or another. Building inspector... some surveying... some computer programing... but that's all behind me now.

Re: Completely brand-new setup and we continue to have issues.
Nothing looks wrong or too cumbersome to service. It's concerning that the burner was changed. Why? Either way it sounds like the thing needs to be tuned, by someone with a digital analyser and who knows how to use it. All is not lost you'll be happy when it's set up correctly.Really? How easy is it to get that flue connector (the smoke pipe from the boiler to the chimney base) off to inspect the base of the chimney? or is that not included in what you call maintenance? And the electric switch has a conduit next to the DHW cold and hot feeds that drop down very close to the top of the boiler jacket that needs to be removed to inspect the flue passages in the top of the boiler. Or maybe that is not included in your maintenance service. It's in the manual for annual inspections.

Calm down there, Tarzan. I don't think @Grallert described his maintenance procedures. I dont know the guy but maybe he's like Eddie Vedder and can swing from the rafters.EdTheHeaterMan said:Nothing looks wrong or too cumbersome to service. It's concerning that the burner was changed.

It's definitely not the most well thought out arrangement, but totally serviceable.
2 Phillips heads to take the roof off and (4) 7/16 nuts to take off the hood and you're in.
An upside-down 5 gallon bucket will get you to pop the flue el and check/clean the base.
It is a narrow room, so why it wasn't turned 90° is beyond me, but I've seen a heck of a lot worse.
And I don't think the OP is coming back so it's all moot anyway.

Related Xmas decorations. Merry Christmas!
This is a Christmas ornament given to me as a gift years ago when I was just starting out.
He has been hanging on my Christmas tree for decades now.
Does anyone out there have something related to our business that is in the Christmas spirit?
Please share it in a post.
MERRY CHRISTMAS to you all.

Re: Another Moline System
Jamie Hall said:Very nice. That cellar looks like a nightmare to work in...
It was. Other than the small pit the boiler was in, everything was uneven dirt covered with 4mil poly which was slippery. No functional lights and head knocker’s everywhere.
The object wrapped in plastic to the right is the old coal boiler which was just moved to the side by the previous installer.

Re: Occupation
Wet heat contractorI will send you some towels, You should stay out of the rain. Or perhaps you can repair all those boiler leaks. Then you can stay dry and still work on boilers.
Re: Help: Blew my transformer and the 120v part of a ZVC
Hello @SENorthEast1895er,
To try to do it with a ZVC may become awkward as you are finding out. You would need a XX for the CH and another independent XX for the DHW to control your boiler, the ZVC does not provide both. I don't know if I would bother to use a ZVC 403-4 for one CH zone.
The ZVC also is used to clean up (or avoid) the mess of wires that multiple CH zone valves and transformers can make, also provide 24 VAC for the zone valves and system status indication.
You maybe able to use the Orange connections for the DHW control. However you still need to have the boiler turn on your only circulator with either a CH and/or DHW call. And this is very atypical, may confuse others in the future.

@109A_5 I was testing off the 120v common (white); should I have been using the 24v common?Well if you are testing on the 24 VAC side of things I would use that common. Since that 24 VAC common may not be bonded to the buildings equipment ground which should be bonded to the 120/240 neutral you were apparently using. So that makes sense why you were not seeing 24 VAC on one side of the fuse.
The relay seems promising, but I’m too inexperienced to figure out the following:The ZVC does have relays in it. However it (in my opinion) does not have the logic or communications to your boiler to work correctly and in concert with your boiler. Your boiler has the means to correctly control the circulator pump(s) as needed with a CH call and/ or a DHW call.
The DHW wires need to go to the boiler to tell it to fire at a higher temp, but they’re also needed at the ZVC/relay to tell it to open a valve/ start a circ.
Honestly, I’m a bit confused about the difference between the ZVC and a relay. Seems like both just connect to the t-stat and tell the circulator to start. The ZVC just adds the ability to control zone valves (and the SR501-EXP-4 adds all sortsa nice features like post-purge, etc)
