PROGRAMMABLE CONTROLLERS VMA16 ( 32-BIT ), VMA18 , AND VMA1930 METASYS CONTROLLERS
support use of a single tool for control applications , commissioning , and troubleshooting to minimize technical training .
• Switchable communications protocols from BACnet MS / TP to N2 protocols or N2 to BACnet MS / TP protocols
• ZFR Wireless FC or SA Bus Interface — Both the ZFR and ZFR Pro Series provide a wireless alternative to hard-wired Metasys system counterparts , offering application flexibility and mobility with minimal disruption to
building occupants .
• Auto-Tuned Control Loops — Reduce commissioning time , eliminate change-of-season re-commissioning , and reduce wear and tear on mechanical devices .
• Universal Inputs and configurable Outputs — Allows multiple signal options to provide input / output flexibility .
• Optional Local User Interface Display — Allows convenient monitoring and adjusting capabilities at the local device .
• BACnet Testing Laboratories ( BTL ) listed and certified — Ensures interoperability with other BTL-listed devices . BTL is a third-party agency , which validates that BAS vendor products meet the BACnet industrystandard protocol .
• 32-bit Microprocessor — Ensures optimum performance and meets industry specifications .
• BACnet automatic discovery — Supports easy controller integration into a Metasys BAS .
• End-of-Line ( EOL ) switch in MS / TP Field Controllers — Enables field controllers to be terminating devices on the communications bus .
• Pluggable Communications Bus and supply power terminal blocks — Expedites installation and troubleshooting .
• Writable Flash Memory — Allows standard or customized applications to be downloaded from the CCT and enables persistent application data .
THE FOLLOWING FEATURES ARE SPECIFIC TO PARTICULAR MODELS
• Models that include a DPT feature a state-of-the- art digital non-flow DPT to provide 14-bit resolution with bidirectional flow operation that supports automatic correction for polarity on high- and low-pressure DP tube
connections ; this pressure sensor eliminates high- and lowpressure connection mistakes .
• A phone jack-style connector on the FC Bus and SA Bus of the VMA16 supports quick connection to the Mobile Access Portal ( MAP ) Gateway , ZFR or ZFR Pro Series Wireless Field Bus System wireless routers , and
network sensors .
• Models that include an actuator feature a fast response actuator that drives the damper from full open to full closed ( 90 °) in 60 seconds to reduce commissioning time .
