Ok, ive been looking around for a controller for my fist tank for the last couple weeks. Australia has NOTHING, how unusual. Found this one on ebay 0 delivered. Not entirely sure how to wire it up and is it a 2 stage, meaning does it switch over to cooling if it gets to hot. Any help from the experts would be greatly appriciated.
