Here is what I got from the Amazon pics:I am in the process of wiring this Inkbird 106VH unit. I am using 110 power. I understand how to wire from power to the unit and to the probe. After all is said and done there are still 4 pins on the back of the controller with nothing connected. #1, #5, #11 and #12
Any idea why these are not used on 110v? Are they for a 220v hookup only?
I think you are ok. Let us know how it all turns out once it is running :D
