Unitary Controller
UNT Series

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 can also be configured as a generic input/output 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 HVAC equipment applications. You may use the UNT as a standalone controller or connected to the Metasys Network through a Network Control Module (NCM), N30, or Companion Supervisory Controller.

• Standalone control enhances system reliability
• Network communications over N2 bus provides facility-wide control efficiencies and cost effective sensor sharing
• Multiple modes of operation for various occupancy conditions provide comfort with economy
• Removable N2 and 24 VAC power plugs allow disconnection of an individual controller without disrupting other controller connections
• Built-in control program library within HVAC PRO software tool allows easy configuration
• Multiple packaging options for both field and factory installations allow for installation flexibility
• Isolated N2 circuitry for more reliable operation
• LED indicator for Power/Zone Bus provides visual indication of proper system function
• Screw terminals for I/O connections available in some models; “Quick Connect” lugs and crimping tool not required
• UNT112/113 include isolated binary outputs when separate power sources are used.
