Of the two terminals, which one is hot and which one is load?

It can be either or. Usually, top is supply, bottom is load.

Do the contacts close on temp drop? I need freeze protection with a 35deg close and 45 open.

not this control you will need to get a control that has both normal open and normal close ( three terminals ) not this one it only has two and it is make on rise.

Compressor kicks on at 0 temperature?

Yes, the 1609-101 is capable of doing that

Can this be hooked up to 220V Walk in cooler?

This unit only has a single pole, for 220 volt you should really use a double pole or a relay, so that you don't have a hot 110 volt going to the machine whether it's running or not. 220 volt uses 2-110 volt circuits. Good Luck.
