What I meant was that the 6006A is tripping about 15 degrees F lower than where the 7224 is reading. I had it set at 145f, and it was tripping at 160-165. Something in my plumbing isn't letting the well give me a good temperature reading, and I think it's the way I have the fresh water feed and Ex Tank plumbed. Both go into the left hand nipple where the 6006A is located, which is what the Axe manual called for, but when the DZ comes on, the line from the Ex Tank stays hot a long time.....which I think is why the DZ doesn't turn off until way after the boiler has cooled down.
Funny thing is the Ex tank is stone cold, I don't know where the increase in the temp in that line is coming from.
