I have to keep reminding myself of that.
It’s not clear from the previous post how I will get one chest freezer to keep things at two different temperatures. That’s because it’s impossible to do that with just a chest freezer.
What I plan to do is to keep the chest freezer cold enough to maintain the lowest temperature I need held. Anything that needs to be warmer will be heated to the proper temperature, probably with a heating pad.
One of the features planned for this temperature controller is a “master cool” mode, where the master cooling device will not run as long as everything is already cool enough. In my case, this would be the freezer, and the idea is that if the freezer does not run constantly, energy will be saved.
