Submittal Form


The Young Regulator Model 2100 is a round, motorized damper.  It features the Belimo, brushless, spring return motor and the Automatic Changeover relay board. 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 2015 features a robust 24VAC motor that powers the blade in both directions for a quieter system.  And a heavy duty spiral shell for extra rigidity.

Use with the T-511 or T-312  (SP/DT/Center Off thermostats) or similar thermostat.
