2165: PO/PC Damper w/ Auto Changeover

Submittal Form


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.

Use with the T-312  SP/DT / Center Off thermostats
