Primary air temperature
For the Supply heating temp FDD to work properly, a SplyAir Central function must be
configured and present. Otherwise, the primary air temperature will always be 32°F
(0°C) in the Supply heating temp FDD.
When a SplyAir Central function is defined, the Primary air temperature will be set
equal to AHU Supply air temperature.
NOTE: Optional DXR input “Primary air temp for after air treatment” is not used for this
FDD point.
