Sorry, I should have given more info:
The Ranco thermocouple is inserted into the keg (I ferment in a Sabco sanke fermenter) via a thermowell so it's reading the beer temp (not ambient temp). I was thinking along the same lines... because it's measuring the beer temp that the controller should react slowly enough as to not start over heating, then cooling, then heating, etc (compared to if it was just reading ambient temps).
Thanks for the help.
edit: forgot to mention - i'm using FermWrap heater to heat.
