Thanks Rob...Fired it up just the way Keystoker had the controls set and everything seems to run well. I do have the triple aquastat set a little low because of the warmer weather,,150/170...
I did want to have my override going to my Modine heater in the basement but that isn`t done yet. The guy doing the install just fed a loop from the coal boiler to my main zone with a honeywell zone valve inline for the override..
He also installed a taco 501 relay for something, not sure yet,and this is where things get odd.
When you shut the switch off on my oil boiler the relay just keeps opening and closing, turn both boilers off and it`s fine. He left late that night and hasn`t been back yet, so that loop is still closed.
Really thought I could take the signal from my 4006b and get it to operate the Modine heater and life would be good,but I really suck at this type of thing
As far as the taco valves go, I just have 2. They just seem so slow to open and they look like a rats nest of wires along with the old leaky gatevalves next to them.
See what I mean by a few issues
