Allow C7089U 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 C7089U Outdoor Sensor is
calibrated at the factory. However, you
can offset the outdoor sensor reading
using Function 35 in Installer Setup.
