Here is my PID, currently wired to control a heater (used for Sous Vide), so it closes the circuit when temperature goes below set point, turning on heater. Does it look like I can move the wire on 5 to 6 and it will instead open the circuit when going below the set point, turning off compressor? (the leads in the foreground are 1-6)
If not, anyone know how I can do what I'm trying to do? Do I need an external relay?
