Johnson Controls Digital Temp Q

I know there are some posts about the Johnson Controls Digital Thermostat Control Unit. My particular question is that I want to use it on a 14 cubic foot fridge freezer combo. So I cannot just drill into the fridge, I will need to close it in the door. Also, I assume that it will shut off my freezer too when it engages, correct? I will need to plan for this, we have some stuff in the freezer. Any work around ideas? Thanks.

Buy a cooler with some ice bags cause you are going to lose your freezing abilities during fermentation.
