The Young Regulator Model 2011 is a motorized round damper with the automatic changeover relay board.Â It can be used to control a single room or zone.Â Two dampers can be linked together; 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 2011 features a Power Open / Spring Closed synchronous 24VAC motor.
