SOFC Attic fan thermostat

[Madmannvan]

Has anyone used a attic fan thermostat in a son of a fermenter chiller? I'm looking at building one this weekend and don't want to spent a whole lot of dough on the thermostat. And thought maybe these would work?
Thanks

No. Their temperature accuracy is crap. You'd also have to try to mount it in the cooler. Just build an STC1000. I think I spent all of $35 on the parts and it is MASSIVELY more accuracy and controllable than an attic fan thermostat. Otherwise you are better off with just leaving the thermostat for the fridge in place and trying to adjust the temperature that way.

Cheers thanks for the help

Wait - isn't an "SOFC" a fan-driven icebox - using actual ice?

While any digital temperature controller will provide tighter regulation than an attic fan controller, we're just talking about spinning a fan, right? Would the potentially tighter control make much of a difference in this case?

Cheers!

I ended up just buying a 20 dollar digital thermostat and a couple sheets of rigid insulation. I have some jugs of water in the freezer and will test it out tomorrow. Thermostat turns fan on and off. Just have to see if it will get down to the temp I needView attachment ImageUploadedByHome Brew1433047128.867538.jpg
