This module provides the flow setpoint controlled by a module control activity (typically a Supply Damper Control). This module controls airflow while keeping the flow within the minimum and maximum flow settings. The module accepts as inputs a mode, heating and cooling minimum and maximum flow values, and a percent flow command from the master VAV box. Based upon the input mode and percent command, the module outputs a flow setpoint and a Control Status. This module uses a heating flow reset strategy that increases flow when the maximum heating output is reached.
This module is implemented as a Hybrid Control Activity.
