If there are issues with the sensor selection and actual sensor connections the display will
change to red letters.
The Fail/Missing means that you failed to connect the sensor that you have chosen in the
checkout tab. In this example the Dry bulb Outdoor air sensor was chosen on the checkout tab
and that sensor is missing in the system.
The 74/connected means that the system is reporting an Enthalpy Outdoor Air temperature at 74
degrees F and the enthalpy sensor is connected which contradicts your set points.
Note the sensor connection is reporting failed in red letters also.
You will need to go back to the configuration screen and change your sensors to match the
economizer controller configuration that is being reported.
