How do you want it to work?

Cold Start?
Etc.

I'm at work till 8 pm tonight, but I have the exact same setup as you but I'm running a taco SR502.

Sorry Grumpie,
I was walking out the door when I got your PM.
Here is what I drew up for my wiring.

The switch on the top left is a 20 amp double pole light switch.

This is setup so the stoker starts as soon as there is a call for heat. So there is no lag. If anyone has anything to add, Please do!

I forgot to add to the drawing.

The B1 and B2 on the aquastat go to your stoker. The C1 and C2 go to your circulator, but your using the taco controller instead of the aquastat for your circulator.

B1 being hot and b2 being neutral.
