Last night I arrived to find that my just delivered Ranco two stage (dual) Temperature Controller didn't come pre-wired. I did extensive searching and didn't find any tutorials in the HBT forums. I am not taking credit for creating this tutorial, just adding here for our wealth of information. I was able to wire mine up in about 20 minutes...with these instructions, it is super easy.
You might consider adding a halex fitting to the bottom of the ranco so that you don't pull the wires off of the terminals when you pull on the extension cords.
The pictures for this are not displaying, does anyone have the instructions with pictures or a link to instructions for wiring the ranco 2 stage controller?
