I want to replace the thermostat on my upright freezer with a digital controller, but I'm not sure from the diagram how to wire it. I know, for example, that if I use the STC-1000, I have to switch the hot leg. However, on the diagram posted, I'm unsure if there is a neutral at the thermostat or if it is a switched hot--which would make the most sense.
Long story short, how do I need to wire a digital temp controller using the wiring at the thermostat. Do I need to run a neutral to where the thermostat is? Any help is appreciated. Normally I can figure this stuff out, but I've had a few home brews and I'm in the mood to order what I need.
