Well, speaking with Matt today, I'm going to move the 6006A over to the supply side of the boiler. That should solve the problem of the high delta between the high and low limit, and also remove the expansion tank line from doing whatever it's doing during the DZ cycle.
It won't be a big deal to plumb, I just have to add a tee and screw in the aquastat, but I have to dump the entire system one last time. Truth be told I have a very very very minor leak at the union off the boiler, so I'll fix that at the same time.
I'm going to run it until Saturday, then make the switch. I'm going to have to re-set my rheostats again, so I'll need a few hours to make sure everything is running right.
Love this boiler though, house is toasty warm (ok, it's not that cold yet, but the DZ cycle is keeping the house at 70F by itself) and it's so much quieter than my old oil fired boiler.
