The Temperature Compensation option compensates the flow and velocity signal for density changes
caused by variations in the process air temperature. The following menus for configuration of
Temperature Compensation are only available if the Temperature Compensation option is purchased.
Additionally, an input signal from an external temperature transmitter or the building automation system
is required; see Section 3.2 for proper temperature transmitter connection and Section 4.1 for
temperature input signal configuration.
