I want to wire in a pid controller for the blower to shut down before a different PID controller shuts down all power to boiler . Very Leary to splice into wiring that might fry my control board. This seems simple, but my PID has 120v when it’s on ( out light on) . Are there settings in the controller that would just cut power like a light a switch , like the same as disconnecting the aquastat. How has other Econoburn users done this ?
