Zone One ™ is a two position stand-alone zone control damper assembly designed to solve isolated over-heating and over-cooling problems. An entire building can also be controlled by multiple Zone One™ dampers.

This damper can be used to control a single room, or by using a number of dampers, zone multiple rooms. The duct sensor, auto changeover control and zone damper motor are pre-wired at the factory. Simply run two wires from a 24 volt transformer, three wires from the thermostat, and you are in business!

Sequence of Operation

The Zone One™ thermostat signals the damper to open or close. Warm or cool air is delivered depending on whether the automatic changeover sensor (located on the damper) senses warm or cool air in the supply duct. The green LED on the printed circuit board indicates the damper is in the open position.

NOTE: The HVAC unit must be controlled by its own space thermostat or discharge air controller. Do not install a Zone One™ thermostat and damper in the area where the equipment space thermostat is located.
