Hi guys, long time lurker first time poster.

Just curious on how accurate the Trane Thermostat humidity sensor is? We live in TX and our humidity levels in the house are always high and the thermostat shows levels close to 70", but the builder has said the thermostat reading is not accurate and is off by 5-7%. Trying to figure out if there's any truth to that or where i can get a more official answer?

The thermostat i have is TZEMT500BB32

Thanks in Advance!
