: The 4081 would be the main thermostat to turn the circulator on when the water gets warmed in the boiler to about 140F and turn the burner off at about 180F. The other control on the pipe (which should be the supply,) would be a secondary high limit set at 200F. As they are the temperatures your system reaches, that might be where they are.
: My main concern would be to make sure the pressure relief valve saves the boiler and you. As you don't have upstairs radiation, you probably can make sure the relief valve is replaced with one with a 30 psig limit.
It in fact does have a #30 pressure relief. By supply do you mean return supply for the boiler or hot supply for the rads? It just seems to me that the way it is wired at the power pile does not at all coincide with with the sticker schematic on front of the boiler. But, again, I am asking ?'s if you know what I mean.
