Thanks for your reply.
Actuall I want to use one PID for the freezer. Have it turn on until it reaches the desired temp and then shut off until it starts to get warm again. You know, the same thing the built in temp controller does.
The second pid will be used to power a fan to circulate cold air for a small cold room. That fan will come on if the temp goes above 68 or whatever.
I just want a controller that I can run 120v to, wire the freezer or fan to, set the temp, and all is good.
