Where is the thermostat on this? this is not included in the instructions, so i can't be certain what needs to be in contact with the tube i'm heatin

Hi Christopher,The black box that has the dial is the one that has the thermostat. So the orange part is the one that needs to be in contact with your pipe. Let us know if you need additional information.Regards,Ana BriskHeat Corporation

For your briskheat hstat101004 on amazon, one picture show temps in f on the dial, the other shows % on the dial - which is it???

Hello Wyatt, The HSTAT tape comes with a dial that shows temperature on F or C depending with model you select. Our BSAT tape is the one that works based on percentage. Please let us know if you need additional information. Regards, BriskHeat Corp
