SKU: 2075 Categories: , , ,


The 2075 round, modulating zone damper by Young Regulator combines the advantages of Variable Air Volume (VAV) and simple damper installation to provide pressure dependent, thermostatically controlled, zone control with automatic changeover between heating and cooling. There is no need for an expensive VAV box.

These modulating dampers are operated with a three-wire, 24VAC, stall type reversing motor. They are controlled by with a single pole /double throw/ center off thermostat like the Young Model T-312 (order separately). In a heat/cool system, the vary the volume of air into a zone to maintain room temperature. They are used independent of a zone control panel to solve isolated over heating/cooling problems.

The automatic changeover relay consists of a duct sensor and relay board. The sensor is factory installed on the damper, upstream of the blade. Then is will keep the sensor in contact with the system air so it always knows the temperature in the duct.

If supply air temp is above 72°F, then the system knows that it is heating. It only responds to calls for heat. Conversely if it is below 72°F, the system will be in cooling mode and only respond to calls for cooling.

The 2075 features the Honeywell 7-Minute motor for smooth, whisper-quiet, airflow changes.

The 2075 is built on a heavy-duty spiral shell. This gives the damper additional rigidity.
