This module is designed to reset the discharge air temperature setpoint based on the zone temperature error. This module should be used only when the VAV is controlling one zone. The module has inputs for the control temperature, heating setpoint, PID configuration inputs, and minimum and maximum heating discharge air temperature setpoint. The module may operate in one of several modes, including Off, Hold, and Htg DA-Tsp Reset. This module has outputs for the DA-T setpoint. This module is implemented as a control activity. The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is true.
