Complete user creation of custom control through block programming adapts MZII to virtually any HVAC sequence or mechanical system. Models with battery backed-up time clock true stand-alone direct digital control optimum start stop, scheduling func- and battery backed-up random access (RAM). Input/output auto trending with adjustable rates continually accumulate and stamp last 48 analog values and last 10 changes of state. Satellite point command capability from controllers eliminates of points. half (0.5) second input to output times make MZII directly applicable static pressure, fume hood and laboratory applications. MICROZONE II Digital Controllers TAC NETWORK 8000 MICROZONE II (MZII) is a fully programmable controller that the TAC NETWORK 8000 Facility Management System family offering. The has the ability to employ custom block programs and run them in a stand-alone The MZII block programming language provides the system operator with 100% for creation of new and unique control strategies. MICROZONE II is easily applied to a wide variety of mechanical equipment includ- those that are application specific. Through the Personal System Interface (PSITM) and Personal System Interface (XPSITM), control programs can be downloaded to all requiring the sequence of operation. With the MZII, the TAC NETWORK 8000 the best of both worlds; full programmability for easy creation and modification custom control strategies, and easy duplication of controller databases for mechanical containing similar or identical control strategies. MZII utilizes state-of-the-art, surface mount technology which helps reduce the and cost of the product while providing powerful product features. Modularity of along with the networking capabilities allow easy expandability as the needs of facility change in the future. As with all other programmable TAC NETWORK 8000 the MZII utilizes non-volatile EEPROM memory to store application control EEPROM memory allows an owner to modify existing control sequences or new ones through the Personal System Interface (PSI). asynchronous at 19,200 baud (adjustable) to global controller. Modular jack for local connection of the Personal System Interface. Terminal (PSI) can monitor all device parameters and has access to all program blocks and at- for complete program editing and creation. Provides up/download capability system maintenance. Device Access connected at one device has access to all network-wide devices on an ASD com- bus. Connection of PSI will not disrupt the network communications the MZII controller and other devices on the bus. NETWORK 8000 to 128 MZIIs per Global Control Module.
