Which term describes the pressure at which a damper motor operates when a full call for cooling is requested?

The pressure at which a damper motor operates during a full call for cooling is essential for understanding how the system responds to temperature changes and regulates airflow accordingly.

In this context, 3 psig is recognized as a standard operating pressure for damper motors when they receive a full signal for cooling. This operational pressure provides the necessary force to move the damper blades fully open, allowing maximum airflow to reach the cooling system.

Operating at this pressure ensures that the system can effectively manage indoor temperatures by adjusting airflow in response to cooling demands. When a full cooling demand is signaled, it's crucial for the damper motor to engage promptly and confidently at the correct pressure to facilitate thermal comfort and system efficiency.

The other pressure options are not standard for a damper motor under these specific conditions, leading to either inadequate performance or unnecessarily elevated operating pressures that do not align with typical HVAC operation parameters.
