Headmaster Controls: What, How, and Why

Several people have expressed their confusion with headmaster controls, their function, how they work, ect... So I'm going to convey how i understand them to work, which helps me most when diagnosing anything, is simply understanding the parts. What its supposed to do, and when is it supposed to do it. Also added a quick explanation on the flooded state condenser, as this is the result of the headmaster doing its job. Crossing my fingers it helps more than hurts 🤞 #hvac #hvacapprentice #hvactechnician #hvacr #refrigerationtech
