Sometimes the heat is unnoticeable to the touch on my fermwrap. If your probe is well insulated against the side of the carboy with some bubble wrap, your controller should tell you the temp of your beer.

Well 3 hrs later it's almost at 72 deg. My brew room is at 59.I guess it works,or the fermentation has risen enough to get temps up, either way I can't feel much heat unless I un tape it and hold it between my hands.
