The Young Regulator Model 2165 is a rectangular, motorized, opposed-blade, power open/power closed, automatic changeover damper. Control a single room or tie up to four dampers together to control a zone. No zone control panel is required.

An integral temperature sensor measures the supply air temperature and the relay chooses between heating or cooling modes.

• Supply Air Temperature less than 72 degrees F = Cooling
• Supply Air Temperature greater or equal to 72 degrees F = Heating

The 2165 features a robust 24VAC synchronous motor that powers the blades in both directions for a quieter system. The opposed-blade design reduces turbulence delivering a more quiet system.
