The three selections for Cold Deck Damper Actuator load the same Outputs for the actuator. The key difference between the three choices is how the hardware definition for each of the Outputs is created in the Details dialog box. The configuration and naming of the Flow Inputs for the Cold Deck, Hot Deck, or Total Flow is determined by the Flow Inputs Locations (Flow Sensor Locations (VAV-DD)) selections, which follow the Cold Deck Damper Actuator and Hot Deck Damper Actuator (VAV-DD) selections.
The selection options for Cold Deck 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. If the Cold Deck is set up for the VAV Controller Integrated Actuator and Flow Sensor, the Hot Deck Damper selection for VAV Controller Integrated Actuator is disabled.
Proportional Actuator: This option assumes that a non-integrated actuator that uses a 0-10 VDC signal is used for the Cold Deck 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 Cold Deck Damper and a non-integrated velocity pressure input is selected.
