Not a noob question. If you Never did it before how would you know?
Do you have a temp sensor, power cord and second power cord with a receptacle on the end?
Basically there should be a gray wire with a black probe. That senses the temp. There is normal power cord to plug into the wall for power. The second cord is the receptacle that the heater plugs into. When the sensor reads your preset temp it send power to the cord the heater is plugged into. When it reaches temp the power to the heater is shut off.
Let’s get @Brad Miller here. He’s should be able to explain how to wire it up. It can also been seen online. A lot of people use them for kegerators.
Oh man thank you both! This community has been nothing but helpful to a new reefer (me) and making it easier to learn. Moderator if you can change Franco to ranco for me that would be great in the title so others that may search out can find the link.
