That is correct, the surface temp on the hot side, is 85f the ambiant air temp on that side is 77f. The temp probe is currently between the heat tape and glass. so.. there is a gap between the heat tape, and the glass, and where the heat tape is "Tented" from the temp probe the heat tape is at its hotest.
