Need a little more information. Do you have seperate thermostats for each zone? Are you using the same circulator pump for each boiler? The way I see this system operating is: On a call for heat a zone thermostat turns opens a zone valve and turns on the circulator pump. A drop in water temp in the boiler causes the aquastat to turn the burner on and raise the water temp in the system. You do not want to break the FF terminals as this will cause the burner control to trip out and have to be reset each time you want to run the oil burner. You can break the TT terminals and the burner will not run. You can get a 2 stage thermostat and let the wood boiler be the first stage of heat and the oil boiler be 2nd stage heat. Wood boiler will heat until fire goes out and a drop in temp in house will turn on oil boiler.
