Important: As of Release 5.1, the Damper Control for UV Cycle 1, 2, or W v51 module replaces the Damper Control for UV Cycle 1, 2, or W v50 module.

This module is responsible for outside air damper control for Unit Ventilator zone control applications. The module accepts as inputs; a mode, a process variable, a setpoint, a low limit process variable, and a low limit setpoint. The module outputs a percent command and the control status based on the input mode and parameter settings. 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.
