Yes there are separate thermostats for each zone. and yes there is one circulating pump for the entire system. The way I have it plumbed now there are two pumps and that system does not work like it should. That's why I would like to re-plumb and re-wire it.
I forgot or did not think about the aquastat being the high and low limit in turning the burner off and on.
"You can break the TT terminals and the burner will not run". I am not sure I understand what you said about breaking the TT terminals. Maybe I should control the power to the high and low limit aquastat to prevent the burner from firing.
So if I go away I can turn the power on the high and low limit aquastat. And if I am home have the power off and if I forget to stoke the fire the gun will not fire and I can build another fire to get the house back to temperature. And for get about my dumb idea of messing with the TT terminals.
