• • ® TAC MICROZONE II Direct Digital Controllers The TAC NETWORK 8000 MICROZONE II (MZII) is a fully programmable controller that enhances the TAC NETWORK 8000 Facility Management System family offering. The MZII has the ability to employ custom block programs and run them in a stand-alone mode. The MZII block programming language provides the system operator with 100% flexibility for creation of new and unique control strategies. • Complete user creation of custom control TAC MICROZONE II is easily applied to a wide variety of mechanical equipment includ- strategies through block programming TM ing those that are application specific. Through the Personal System Interface (PSI ) and structure adapts MZII to virtually any HVAC TM Xtended Personal System Interface (XPSI ), control programs can be downloaded to all control sequence or mechanical system. devices requiring the sequence of operation. With the MZII, the TAC NETWORK 8000 • Models with battery backed-up time clock provides the best of both worlds; full programmability for easy creation and modification provide true stand-alone direct digital control of custom control strategies, and easy duplication of controller databases for mechanical with optimum start stop, scheduling func- equipment containing similar or identical control strategies. tions, and battery backed-up random access memory (RAM).

Local Terminal (PSI) PSI can monitor all device parameters and has access to all program blocks and at- tributes for complete program editing and creation. Provides up/download capability for system maintenance. Network Device Access PSI connected at one device has access to all network-wide devices on an ASD com- munication bus. Connection of PSI will not disrupt the network communications between the MZII controller and other devices on the bus. TAC NETWORK 8000 Up to 128 MZIIs per Global Control Module. Shared network data includes all physi- cal input/output points plus capability of WINDO and EMS blocks which are program definable. Table-1 Model Chart.
