EngyVolt devices may be compatible with earlier releases of N2 software, but Johnson Controls only
supports integration issues on the above.
Support for Metasys integration
Please contact the nearest Jonson Controls Energy Efficency or Johnson Controls System & Services
representative. The address can be found on the Johnson Controls website.
Design considerations
When integrating the EngyVolt device equipment into a Metasys Network, keep the following
considerations in mind.
Make sure all EngyVolt device equipment is set up, started and running properly before attempting
to integrate with the Metasys Network.
A maximum of 32 devices can be connected to any one NCM N2 Bus segment, or up to 100 devices
if repeaters are used.
From the instrument set-up screen, the Coms option must be set to N2, then the address set to the
required value. All port settings will then be set automatically, see below.
