Allow C7089B Outdoor Sensor to absorb
outdoor air for a minimum of twenty
minutes before taking a reading.
With an accurate thermometer (±1°F
[0.5°C]), measure the temperature at
the sensor location, allowing time for the
thermometer to stabilize before reading.
Then verify the sensor accuracy by
going into installer Test #20. This will
show you the outdoor temperature.
Calibration
The C7089 Outdoor Sensor is calibrated
at the factory. However, you can offset
the outdoor sensor reading using
Function 35 in Installer Setup.
