Exhaust Damper logic requires that a separate actuator and velocity pressure transmitter are mounted on the Exhaust VAV Box. The Exhaust Box can is set up to track the flow delivered by the Supply VAV Box to pressurize/depressurize the space under control.

The two selections for the Exhaust Damper Actuator load the same Inputs and Outputs. The key difference between the two choices is how the hardware definition for each Input and Output is created.

The selection options for Exhaust Damper Actuator are:

  • Proportional Actuator: This option assumes that a non-integrated actuator that uses a 0-10 VDC signal is used for the exhaust damper and a non-integrated velocity pressure input is selected.

  • Incremental Actuator: This option assumes that a non-integrated actuator that uses two binary outputs for incremental control is used for the exhaust damper and a non-integrated velocity pressure input is selected.
