Most of the relays are rated for 15A @ 125V. The rating of the contacts and other components at lower voltages is debatable, but should be at least 10A, and probably slightly more.

Here is a question from a total novice. Why do you go through all the wiring joining and use the ground as neutral? Can't you just run power to the unit, one set of in wire, and then one set of wires from cooling to the plug as well as the heating to plug? I note there is not ground wire used.

On my diagram, all grounds are connected, all neutrals, and all constant hots. The only neutral that goes into the controller is to power it. Everything else is constant or switched

I see all that now, thanks! On this setup you were going to run a frig and fan. Run the frig on the cool cycle and the fan on the heat? Or run both on the cool? Or wire one outlet constant on and run the fan constant on?

Ok I’m on the hunt for an old fridge to use as a fermentation chamber for my 1 gal batches and have this device on the way from HK. I’m going to follow these wiring instructions and I think this will be an easy build. Now I have some dumb questions. So you set the fridge temp to the max (warm) and then use the STC1000 to control the cold to keep it at your desired fermentation temps? My fridge will be outside here in GA. So it won’t get too cold this winter but I can see some dips into the 30s. Will I need to run some sort of heating device on the heat outlet or will the fridge maintain a constant 58-70 degrees? I think I understand what this device will do but want to make sure I have it set up properly to maintain my temps. I will have to re-read this thread.


Now reading the post above why would you have a fan on the cooling cycle? I thought you would want your fridge on this outlet. I guess this is where I get confused??

I have two outlets, one for heating and one for cooling. The fan is plugged into the cooling outlet with the fridge. If you're gonna get down to the 30s I would definitely get a heater. Walmart sells a personal heater that'll work for around $11. You have to make sure it's not computerized otherwise it'll need a user to manually turn on and won't work for this application

You'll almost certainly need a heat source in the fridge then as well, unless your ferments are putting out a lot of heat.

If you use a duplex outlet for each function (heat and cool and maybe one constant hot) then you can plug two devices in - so the refrigerator and fan can both be on the cool circuit.

Thanks for the replies all. Would something like this work instead of a fridge?

Sure, but you'll want to either cover the glass with foil or something else to block the light, or use completely opaque fermenters. UV light will skunk a beer in no time.
