Could well be horse-pucky Rocket.. I'm a graduate Therapist not a graduate Engineer!
AFAIK, precise thermostats are more costly than a couple of resistors�
My point and Gelato's (I assume) we are looking for a best fit here�.
We want this puppy to work for you under a number of widely occuring variables.
