Re: HVAC for workshop - Controlling rust?

I don't want to keep the heat over 40 to 50 degrees in the winter except when I'm in there. Will the temp changes cause rust? 

I live in Saskatchewan (see previous Winnipeg response for temperatures).

The garage is kept just barely above freezing (2-3 degrees C) in winter unless I'm working.

It was done on the cheap using a standard bimetal thermostat, but mounting it with just one screw. The thermostat only goes down to 10 degrees, but by twisting the whole body of the thermostat to align one of the corners with marks on the wall it can be set to lower temperatures.

I also don't want to air condition under 80 degrees or so unless I'm in
the shop. How can I remove enough moisture from the air to keep the tools rust free?

As suggested earlier, a straight dehumidifier will be cheaper to run than an AC. You could then add an AC for when you want to work in the heat.
