We’re building a cold room for processing deer and beef with a 240v window air conditioner. I’m wiring in two PID controllers to bypass the units normal thermostat to allow colder temperatures with one and prevent the coils from freezing with the other. I understand the wiring of the PIDs and the SSRs that they run, but I’m not quite sure where to tie these in to the wiring of the AC unit. The black wire goes into the compressor relay and the *********** leg goes directly into the capacitor. Which one do I tie into?
