6.2.3. Temperature Compensation
Temperature Compensation corrects the flow signal for density changes caused by variations in the air
temperature. An input signal from the AAON Temperature Transmitter is required; see Figure 1 in
Section 3 for proper temperature transmitter connection and Section 6.3.2 for temperature input signal
configuration.
6.2.3.1. Temperature Units
The Temperature Units Menu allows the user to select the appropriate temperature units for the job. The

6.2.3.2. Temperature Values
The Temperature Values Menu allows the factory or user to set the minimum and maximum temperature
range values that represent the input signal from the external temperature transmitter or the building
automation system. Since the AAON Temperature Transmitter has been supplied the minimum and
maximum temperature range values of -30°F to 130°F have been preprogramed.

If the temperature values are changed from the factory settings and the new temperature values cause the
existing Operating Range Value to be outside the new calculated Minimum or Maximum Full Scale
Value, the below Warning Message will appear and the Operating Range will be reset to the new
Maximum Full Scale Value by pressing Enter. The display will automatically jump to the Operating
Range Menu allowing the user to enter a new Operating Range Value. This can be accomplished by
performing the steps under Section 6.2.1. See Temperature Range Example below.
