Brand new Dual Stage Ranco Temperature Controller $100 ship
I bought a dual stage Ranco Temperature controller for my DIY chiller. After the first prototype did no perform as well as I'd hoped, I ended up just buying a compressor chiller. Therefore I do not need the Ranco anymore. The controller has never been used other than to test it. I have installed the wiring and plugs (put about 15$ into it to do so). Let me know if anyone is interested.
Make it idiot proof and someone will just make a better idiot.
