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

If an Exhaust Damper is selected, Box Fans cannot be selected.

The selection options for Exhaust Damper Actuator are:

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

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