Very well done. These vids save me a lot of time explaining to my guys and the principle also applies to many different boiler applications. If you can get the steam boiler down then the others are cake. Maybe next time you can show how to connect a digital tstat with an outdoor sensor to a oil steam boiler and set it up. Thank you!

Is it a way I can make a test board

tremendous teaching, there are very few who speak the way you speak with your heart in your hand explaining the shape of the wires How they workI'm going to call you the Ultimate Warrior

Great video thanks for sharing your knowledge!!

very helpful Mike.

Great explanation

AMAZING video!!!

great description of steam boiler wiring. you pointed out that smart thermostats get disconnected while water level check. is there a solution to make thermostat up at such condition?

My solution is to never use smart thermostats on steam boilers. lol. But short or rewiring the boiler circuits, the best approach is to use a dedicated transformer just for the stat and an isolation relay to cut into the boiler circuit.

Very cool

You're most welcome

Couple question: 1. If there is no power on the G terminal can I assume there is problem with the LWCO? 2. If I have call for heat, but nothing is happening on boiler. I jump from R terminal to Y terminal (bypass the thermostat). Maybe I should jump out G and Y better. The boiler fire up, it will be the thermostat issues? 3. What is the W terminal for? Thank you Mike if you have time answer my question. You have great and easy explanation on wiring.

1. It depends on the boiler and the wiring, but on the diagram in this video, no power to G could be a lwco situation, but you'd have to make sure you have power coming into the lwco and that you dont actually have a low water condiction to confirm a lwco problem. 2. It would be better to jumper at the thermostat between R and W. G to Y can indicate but doesnt conirm a thermostat problem. It could also be a tstat wire problem. Jumpering at the stat with the boiler firing up confirms the tstat wires are ok and its actually a faulty stat. 3. W terminal is dead. There's nothing wired to it. Its there so that it can be powered and used for accessories if desired. I was on one steamer recently, for example, that had a hydronic loop on it also. W was used to power the zone valve.

I have this same setup for my steam boiler. Once in awhile my my nest v3 says low power. I have the power connector w/y to the Y transformer, C to the C on the transformer & R to the R on transformer. Is that right or should the R go to G on transformer? Thanks for your input. You have great informative videos

It's probably better off on the R terminal. G term will not get power on low water conditions. Nest thermostats don't play well with steam systems. I would suggest disabling some of the smart features, if possible, both to reduce power needed for the stat (possibly aiding in charging the batteries) as well as minimizing how much the Nest wants to regulate the boiler timing. Steam is a longer heating process and you'd probably avoid some issues by reducing Nests micro-managing tendencies. I'm also aware that Nest has a N260 nuisance bug that a lot of people get when connecting a power connector. They don't seem to have an answer for it.

Can you draw out a diagram with arrows showing start to finish of sequence of operation with step by step numbered explanations? This video is great but to fast for me and I'm not grasping the big picture. I did a lot of steam installs over 20 yrs ago as a helper but forgot a lot since then and I'm about to reenter the industry. I got pretty much everything else down in diagnostics right now except for steam. Seems that you pretty much know your shit!

Ok pull it out. I'll measure.........
