UHC-302 VAV Terminal Unit Controller

A flexible, feature-rich but cost-effective solution for single-duct pressure-independent variable air volume terminal unit applications. The UHC-302 maintains constant space temperature by configurable, energy-efficient, sequenced control of fan, damper and heating sources, supporting over nine styles of VAV boxes.

• Configurable resistive inputs for space temperature (required) with/without bypass button and optional setpoint adjust, open window and occupancy sensors
  

• Digital and analog outputs simplify connecting to a variety of digital, floating and analog-controlled actuators
  

• Secondary heating control extends options for comfort
  

• Optimize energy usage with optimum start, demand limiting, occupied/unoccupied/standby setpoints and variable speed fan control
  

• Side loop provides independent control using spare inputs and outputs for simple HVAC applications
  

• PI loop control and built-in alarming, trending and scheduling
  

• Combined with the UHC-300, an unbeatable VAV solution
  

• Meet ASHRAE minimum ventilation requirements: the UHC-302 in conjunction with a UHC-300 controlling the air handler allows you to maintain required outdoor airflows to the space by enforcing a configurable vent ratio
  

• LonMark certified with Space Comfort Controller functional profile #8502
  

• Easy-to-use LNS plug-in software simplifies configuration
