Stc1000

[nicklawmusic]

I built a fermentation temp controller a while ago and decided that I needed to build another so I can have two beers on the go at once.

Being the clever sod I am, I decided to buy a single phase 2 gang plug socket, not realising that in an ideal world, I need two single plug sockets.

I tried wiring it up to heat only (as that's all I really need a my cellar is pretty cool) however, when I tried to get the STC1000 heater to kick in, one of the sockets sparked at me.

Any ideas on a wrong diagram for a double plug socket? Or do I need to abandon and buy two single sockets as my first unit has?

I know I wired mine incorrectly the first time. I was used to bringing the hot and neutral to the connection but the way the stc is wired you bring the hot in one side and out the other to the hot on the outlet. All the stc does is just interrupt that flow. So what you end up having to do is jumper your neutral coming in to the neutral on both the heat and cooler connections. Then you run the hot into each plug on the stc and out the other side to the hot connections on both. I'll see if I can find a link to that wiring diagram.

seems like most outlets have a connection tab that makes them common. Usually you can just remove the silver plate that connects the two terminals on each side and then they become separate outlets.

If I understand you're trying to only run heat to one of the two outlets? Most 2 socket plugs will have a brass tab on one of the sides that can be broken with a pair of pliers to allow them to share a ground and neutral but have separately switched hot sides (though you should double check instead of trusting me on which is which). Most YouTube build videos will show this step and this allows you to use one of the two outlets for the heating side and one for the cooling if you ever decide you want it.

Not in the UK they don't. Totally different plug set up.

Whoops, suppose I should have clarified.
