I strongly suggest any of you avoid buying this
I wasted my time and money arsing around with something that almost certainly hasn't been tested by the manufacturer before being sold. The supplied screw doesn't fit the back thread on the STC-1000 and theres no where near enough space to fit the wiring in behind the unit. The back cover also snapped as soon as I threaded a wire through it but thats probably partially my fault.
If anyone has a link to a suitable junction box or similar, I'm all ears. It has to be all proper for a commercial brewing environment. No more insulating tape and gaffer for me anymore
