I am currently troubleshooting why a roof top air make up is not running at all. I believe I am just missing a simple component somewhere. There is a NC contact that requires 120 inside the make up air. It is not getting the required 120 and I have change led out all micro switches inside the Ansul system. Which did absolutely nothing for me. What am I missing in between? I basic **** off switch somewhere possibly?
