Important: As of Release 5.1, the Cooling 2 Position Valve v51 module replaces the Cooling 2 Position Valve v50 module.

This module controls a two-position cooling valve within a zone control application. This module determines the required percent of capacity and then provides the appropriate control inputs to a MSC. The module accepts as inputs a mode, process variable, and a setpoint. Based upon the input mode, the module produces outputs intended to be connected to the MSC module that controls the actual two-position valve. 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.
