The selections for Supply Damper Actuators provide the same Inputs and Outputs for the actuator and velocity Inputs. The key difference between the three choices is how the hardware definition for each Input and Output is set up.
The selection options for Supply Damper Actuator are:
-
Integrated Actuator: This option assumes that you are using a VAV Controller that has the actuator and velocity pressure inputs packaged with the controller.
-
Proportional Actuator: This option assumes that you are using a non-integrated actuator that uses a 0-10 VDC signal for the supply 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 supply damper and that a non-integrated velocity pressure input is selected.
