Important: As of Release 5.1, the Flow Setpoint (VAV Single Duct) v51 module replaces the Flow Setpoint (VAV Single Duct) v50 module.

This module provides the flow setpoint to be controlled by a module (typically a Supply Damper Control). This module is designed to control zone temperature while keeping the flow within the minimum and maximum flow settings. The module accepts as inputs a mode, a process variable, a setpoint, the measured flow, and configuration values. Based upon the input mode and configuration settings, the module outputs a flow setpoint, a flow percent, and a Control Status. 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.

This module provides EWMA diagnostic values calculated by the PID. Controllers have the ability to collect data about their inputs, outputs, and internally calculated variables. Inside the controller, the EWMA minimizes memory requirements, reduces communication traffic, and provides an easy way to analyze collected data. See EWMA Diagnostics in the Commissioning a System section for more information.

You can view and modify the modules in this group’s logic.
