Product Name(s): RZ-moZaic Intelligent Area Controller/Gateway
Product Description: The RZ-moZaic is a graphically programmable, LonWorks-enabled controller that provides trending, alarming, scheduling, monitoring and control for a network of Richards-Zeta LonWorks controllers and any third-party LonWorks controllers. The RZ-moZaic can also function as a gateway and will attach to, communicate with, supervise and monitor a network of third-party DDC controllers. The basic RZ-moZaic unit does not come with any I/O, but will accept expansion I/O to function as a general-purpose stand-alone controller.
Product Application(s): The RZ-moZaic functions both as a controller and a 3-way Gateway, between 1) LonWorks to 'Legacy', 2) RZ to 'Legacy' and 3) RZ to any other LonWorks device. Controller functions will support general HVAC applications including air-handling units, chillers/boiler/central plant control and distribution systems, data acquisition, and other multi-equipment applications. Also provides a RZ graphical programming and monitoring front-end for LonWorks and Legacy systems.

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Yes
How many total trend values can be stored? Information not provided.
What is the controllers role in trending? Stored in controller RAM until called for archiving by the workstation.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Can be set two send up data or overwrite the data.
Programming Method(s) All RZ controllers use PerfectHOST for Windows (PHWin) graphical application programming. 'Templates' (logic blocks) are used to develop control sequence logic for all controllers. Application-specific controllers can alternately use pre-developed sequences called 'macros' that are written for specific types of equipment and/or sequences.
Resident vs Non-Resident Program Execution All programming resident and executed at the controller.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
