Important: As of Release 5.0, the Fan RF or EF BSP for UL-864-UUKL v50 module replaces the Fan RF or EF BSP for UL-864-UUKL module.
The Fan RF or EF BSP for UL-864-UUKL module controls a variable speed fan and Building Static Pressure (BSP) in an AHU application. This module accepts building static pressure, PID tuning parameters, and setpoints. The module has outputs for controlling a variable speed return fan. This module accepts commands from a FSCS. The FSCS input takes precedence over the mode input. This module also incorporates tracking the overridden value of the actual output object (AO, PAO). The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is not Normal.
