Up their game in regards to what? You've said you have the c4-therm and now state you can fish wire anywhere. I've already pointed you to the knowledge base that references the ability to average temp across multiple Aprilaire 8051 sensors. BTW the 8052 duct/outdoor sensor(s) can be part of the equation as well, they both read the same/resistance. What am I missing here that you need in addition to that?
