Possibly simple question: I have a bunch of 10k @ 77f type 2 thermistors for hvac duct sensing. Some of these are 20 yrs old. Some appear to be not reading correctly. If I go to the controller input, and put a 10k resister across the input, I should get 77F reading on the building system readout, correct? or?. The inputs are configured for 10k type 2. What I am seeing is 52F, 46F, and other numbers when the 10k resister is connected. I have found only 1 that reads 77F. I think all thermistors, type 1,2 etc should read [email protected] 10k, correct?
