I have been looking into building a cold storage room for some time and finally want to start the process.
I am interested in building a cool bot clone. Have any of you guys been able to build a controller that is similar to the cool bot? I have searched and haven't seen a build yet. However at $300 I am interested in taking my time to see if it can be done cheaply.
For my use I will likely keep a storage temp around 45F or so (I might be able to simply get away with a Johnson controller and not have to worry about freezing).
Thanks for any recommendations, or possible build attempts you may have to offer.
Key aspects to the cool bot:
1. Some kind of therm. resistor that tricks the A/C unit temp probe into thinking the room is warmer than it is so it will not shut off.
2. Freeze over protection by placing a probe into the A/C units fins that I assume kills the power when the temp goes below a certain set value near 32F
That last part could simply be controlled by a 1 stage Ranco in the cooling mode.
I don't have any experience with electronics that would help with aspects 1 and 2. The ranco part is of course the easiest.
