The ATC1000 is a single relay, rated at 30A (allegedly, there's some debate on that in the reviews, but looks like 13A minimum), so you can hook up *either* a heating element *or* a chiller, but I believe switching which mode its in is a bit of a pain.
So..
If you're using it for things with a load < 10A and need, or might need in the future, heating and chilling then an STC1000 is your guy - e.g. a fermentation fridge
If you're using it with a load > 10A, and only need to heat or chill, then the ATC1000 is the one - e.g. a HLT
If you're using it with a load > 10A and need to heat and chill (or if you need more than one relay for other reasons) then you probably want an STC1000 and some external SSRs.
Agree with Grumpydev.
If you want to control a HLT or Boiler this (30A model)is great. If your looking to cool/heat a fridge, its no use for that. An STC1000 or ATC800+ is.
The 30A model can be used to either control heat or cool, but not both, it cannot switch between them. It can only control either one.
I use mine to heat HLt to my required temp and hold it there.
I then use it to check my strike temperature in my mash tun. I then leave it in the mash to monitor mash temperature.
I then use it to on my boiler to bring close to boiling and hold until i'm ready to remove it and do the boil.
I then chuck the prob back in at 15mins to sanitise, and then monitor cooling down to my required temp.
Best £16 I've spent on brewing. Well I did pay £6 for a project box from Maplin to keep it safe.
I just use the included temp probe, seams to work well.
I expected it to come from China and take a month, but it arrived in 1 week and I think it came from hong kong.
