REX C 100 PID for Fermentation Chamber

Hello All,
I bought a couple of these inexpensive temperature controllers off ebay. Before I start wiring (and unwiring :cross, I was just wondering if anyone has had any experience using these to temp control a keezer or fridge used as a fermentation chamber.

My garage is pretty cold so I'd like to set it up to be simultaneously plugged in to the power supply to the fridge and to a simple heating element - this way I can use the same controller year-round, especially in the spring and fall when the temperatures get variable.

Any input would be much appreciated!

I notice that this thread is about 4 months old, but I just acquired on of the same PID's that I will be using for my fermentation control. When I get it done, I will post my stuff here, unless you have already found it, in which case, can you post it?
