WattMaster VAV System users now have a complete Windows Based Graphical Interface intended to ease the user interaction with their building HVAC system. It provides standard, easy to understand status screens for each type of WattMaster VAV System controller installed. Prism software has provisions for custom screens which allow floor plans, equipment photos or user defined summary screens to be implemented by the user to meet their own individual needs.

All controlling setpoints, trend logs and alarm conditions are accessed in the Prism environment. Prism can be configured for a direct On-Site installation, a Remote Modem connection, or a TCP/IP Internet connection to several installations.
