Need help with a link for a seller who has this type of temp controller. I live in Cairns and I don't think I will need a STC-1000 as I don't need the heating control. I have put down 3 brews so far and each time i've struggled with temp, even with the FV partially submerged in water with bottles of ice changed twice a day 28 deg is all I can achieve. Have sourced a fridge just need the controller. Thanks in advance.
