The Johnson Controls AS-VAV111-1 is a Variable Air Volume Digital Controller used to control single duct, fan-powered, and supply/exhaust VAV box configurations. Can be used as a stand alone controller or connected to the Metasys Network through a Network Control Module(NCM) or Companion through an N2 bus.
Features
The AS-VAV111-1's standalone control creates system reliability, while network communications over an N2 bus allow for facility-wide control and cost effective sensor sharing. Multiple packaging options offer installation flexibility, and the built-in control program library eliminates programming. A single earth ground connection is allowed by isolated N2 circuitry, and the expanded memory makes for larger download and application capabilities. The N2 and 24 VAC power plugs are removable which enables a user to disconnect of individual controllers without disrupting additional connections. An LED indicator provides a visual indication that the system is functioning properly.
