Yes, I left it unplugged overnight and the settings remained.

This uses a NTC thermistor (measuring resistance) and is not compatible with a thermocouple (measuring voltage).

It would depend on your refrigerator. Most refrigerators are cooled from a single compressor and coil system. Some have one compressor and two coils. You would need at least this dual-coil setup.

Most refrigerators are cooled from a single compressor and coil system. Some have one compressor and two coils. You would need at least this dual-coil setup. The wiring hack would be very tricky and discouraged for a DIYer. These kinds of fridges are already expensive and messing with the wiring would void the warranty and possibly destroy the machine. Probably easier and safer to get a dedicated fridge and freezer for each purpose you need. They come in all shapes and sizes, so space really wouldn't be a problem. see less

Temperature range for activating controller. Default is 2 deg F and it can be set between 1 and 30 deg F. It is meant to prevent over-cycling.

The sensor appears potted quite well. For severe duty it may be placed in a well.

They are for mounting into a rack.

I'm using mine to control a 125 watt heat lamp so I would say yes, a 20watt heat strip would be well within the rated specs.

You are probably looking for a analog temperature controller for your system. This controler does on /off only and has a control band of a couple degrees. Not suitable for your application

The probe is potted, but I don't think it looks like a probe designed for submersion. It is however a standard 10kohm NTC element which can be easily replaced with a waterproof version. I added extension wires to my probes to increase the measuring distance beyond 1 meter. There is also a calibration adjustment if necessary.
