So today I was helping a buddy hard wire his STC-1000 to his fridge for temperature control (cooling only). We wired the STC-1000 per the schematic below and had no luck getting it to kick on the compressor to the fridge. If you look at the schematic below we took wire number 10 which came from our plug and wired it to terminal number 1 on the STC-1000 which is L1 for the power. Then we took wire number 10X2 which is the neutral and wired it to terminal number 2 on the STC-1000 which is L2 for the power. I jumpered between terminal 1 and terminal 7 on the STC-1000 to supply power to the Hot side of the "cooling" set of contacts and I jumpered from terminal 2 on the STC-1000 to the fridge to supply the neutral. Then we ran wire number 11 from terminal 8 on the STC-1000 to the fridge. In my mind all of this should have worked out. Once the temperature probe got to the set point it should have closed the "cooling" set of contacts and kicked on the compressor to the fridge. Is there something wrong with my wiring or is there something I am missing? We know that the fridge works if I eliminate the STC-1000 and just wire nut everything together. I will post pictures of my physical wiring so you can double check what I have done (the wiring is sloppy, we made due with what we had haha). Please let me know if you have any insight into why this wouldn't be working. Thanks
