Review on Origin Digital Elitech STC-1000 Temperature Controller - 110V Centigrade Thermostat with 2 Relays by Jerome Pernell

This is the standard temperature controller and appears to be the most affordable Revain unit. I connected it to control the fermentation temperature. This unit is in degrees Celsius only; If you crave Fahrenheit readings, grab the Inkbird ITC-1000 Inkbird 2-Step Digital Temperature Controller, Fahrenheit Thermostat with Sensor for 3D Printer, Freezer, Fridge, Hatch, etc. for a little more money. The connection diagram is correct and corresponds to the electrical regulations. There are several other schematics on the web that work but are a bit dangerous or out of spec. It is recommended to purchase some wire nuts, a 16 or 18 gauge extension cord, and a small 1 foot extension cord. Cutting these cords gives you all the connections you need and is a lot less of a hassle than plugging in an outlet.
