VAV-332-XMV
Configurable VAV Terminal Unit Controller

A configurable, feature-rich but cost-effective VAV box controller for single duct pressure-independent or pressure-dependent applications. The VAV-332-IMV maintains constant space temperature by configurable, energy-efficient, sequenced control of fan, damper and heating sources and is pre-configured for over nine VAV box styles.

• Dedicated resistive input for space temperature with/without bypass button
  

• Universal inputs for digital, resistive or voltage sensors such as supply air temperature, setpoint adjust, occupancy detection, concentration, light level, pressure, and airflow
  

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

• Floating outputs provide clockwise/counterclockwise control for external, in-place damper actuator
  

• 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 additional HVAC equipment
  

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

• Meet ASHRAE 62.1 - 2004 minimum ventilation requirements: the VAV-332-IMV 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 or by using CO₂-based demand control ventilation
  

• LonMark certified for guaranteed interoperability
  

• Free, easy-to-use plug-ins for LNS and wizards for Niagara^AX simplify configuration; free air balancer software streamlines air system balancing
