I recently had an issue where my trane ahu discharge air sensor reading at the front end was out of range (ten degrees below actual) despite an acceptable ohm value at a given temp (i checked it with the charts for a 10k type 2 sensor), i even swapped it with the return discharge air sensor (same part#) i went into tracer summit anolog inputs and attempeted to offset sensor, and noticed no change at graphic, Do i need rover to make change? Fyi there is an mp580 on ahu.
