Caution: Complaints of inaccurate outside sensor readings are very common and
can almost always be shown to be the result of poor sensor location.
Note: All sensors utilize the same type thermistor sensor element. For troubleshooting
sensor problems, refer to temperature sensor resetting instructions in Section 3
of this manual.
