Inside the ranco is a relay. The relay has a common, to which you connect power. Then, it's arm switches between two contacts. It doesn't just "open-circuit".

So, you want to wire each of those 2 contacts to separate outlets. You only want to plug in one device (either the freezer power OR a heater) and it will just work. If you think about it you will probably figure it out.

It would work if you pluged in both devices, but there needs to be a gap in temperature where nothing happens (hysteresis) so you don't get short-cycling of the compressor and heater. It might work, but I'm not sure; I think the johnson had 3 or 5 degrees hysteresis, but maybe that's not correct.
Doh! Thanks for the reply. I should have checked back here before I ordered the Love controller. I'm sure I can find a use for the analog one.
