greetings:
  has it been considered that if you attach the cold side to something
in the intake plenum, then the air inlet temp gague could be used to 
determine the temp of the cold side of the thermo?  this would require
us to fix the temp in software, altho we could use the hardware to get
a ballpark figure & tweak the final number based on how far off 0deg f
we actually are... or is this another case of engineering overkill? :)
