This alarm is fixed and cannot be adjusted.

Outdoor Humidity Sensor Failure Alarm

When the sensor reads a value that is outside of the
acceptable 0 to 100% RH range, an alarm will be
generated indicating the sensor has failed. This alarm
condition will disable the economizer when the mode is
set to temperature and humidity or enthalpy.
This alarm is fixed and cannot be adjusted.
