Re: Situational Water Hammer
Show us your boiler piping, floor to ceiling. All sides.
Especially where the water returns to the boiler.
Take note of the relationship of the actual water line level in the sight glass and the height of your return pipes. Also, the Hartford Loop, which is the jump up from the floor to where it connects to the return pipe on the boiler.

Re: Steam traps
It's called the yeouch test. Get the radiator so it is hot all the way across. Really going. Then... the outlet from the radiator to the trap should be steam hot. You can't hold your hand on it. The outlet from the trap, however, should be noticeably cooler. You still can't hold your hand on it for any length of time...
Or you can use an IR thermometer on it. Inlet to trap should be at least 4 degrees hotter than the outlet, and more is better assuming the radiator heats...

Re: NEST With Two Wires
If you want set back temp just go back to this hundred year old Minneapolis.
All problems fixed.

Re: Constant Circ to balance room temp? Or add more baseboard
Yeah, the deck is stacked against you with that install. I'd start over with a proper LLH installation.
Don't let Viessmann see that install it, they'll choke on their weinerschnitzel

Re: Constant Circ to balance room temp? Or add more baseboard
Hey, I just learned -41 is the approximate meeting point of C and F. And it only took me 56 years. For a second there I thought Google was broke or I entered the Twilight Zone.
Anyway, Viessmann is all about constant circulation. An indoor sensor. An outdoor sensor, and off you go. But of course it must be designed and piped correctly.
Maybe the least invasive would be to replace the thermostat with something like a Honeywell T9 where you could connect wireless sensors.

Oh yeah!
And the three laws of thermodynamics:
Furst Law: you can't win.
Second Law: you can't even break even.
Third Law: your initial stake is zero.
