The Unitary (UNT) Controller is an electronic device for digital control of
packaged air handling units, unit ventilators, fan coils, heat pumps, and
other terminal units serving a single zone or room. It also can be
configured as a generic Input/Output (I/O) device for basic point
monitoring applications when used within a Metasys Network.
You can easily configure point inputs and outputs, and software features to
control a wide variety of Heating, Ventilation, and Air Conditioning
(HVAC) equipment applications. The UNT may be used as a standalone
controller or connected to a FMS.
When connected to a FMS, the UNT provides all point control information
to the rest of the network. The devices communicate through an N2 Bus.
For a smaller facility, the UNT can function as a standalone controller.
Figure 1 illustrates the UNT.
