The instructions on this say to wire black to 1, 5 & 6 but the diagram says 1,5 & 7. You may want to fix that.
Perfect timing on this since I just bought one of these temp controllers a couple weeks ago. Thanks!
Good catch. I updated the directions to be inline with diagram.
Yeah, and it looks like the white wire for connection #2, and the upper outlet should actually go to the white wires' orange connector. The internal relay is good for 10A but larger freezers can draw 12+A on spooling up. When I build my second controller I bought a couple of 25A solid state relays that I drive with the TC.
I hadn't seen anything about this in my research. Are you saying just go from STC-1000 connection #2 to the orange wire connector instead of going into the outlet? Where do the solid state relays come into play?
Edit: Found this pic from someone who gutted the STC-1000, which I think shows that the relay is rated to 15A
I think he means from from the outlet to the plug. Because you made 2 powers go to the outlet. Hopefully rjharper will verify.
Looks like you are good to 15A on a 110v circuit.
To clarify the wiring, the image on the AHA page shows the neutral wire (white) for the power supply routing through the upper outlet and into the heating relay. While I'm not familiar with the STC-1000 directly, that indicates to me that the Temp Controller wont be powered unless the heating relay is closed, AND there's a load plugged into the outlet to complete the circuit. I.E. I cant see it working that way.
To correct the diagram, I would connect the white line coming out of 2 directly to the orange cable connector that holds the ground connected for the cooling circuit. Similarly, the left wire on the upper outlet needs to go to the neutral cable connector as well. That way the Temp Controller is powered independently as are the two switched circuits.
EDIT - it's easier just to fix the diagram!
