MICROZONE II I/A Series MICROZONE II (MZII) is a fully programmable that enhances the I/A Series Facility Management family offering. The MZII has the ability to employ custom programs and run them in a stand-alone mode. The MZII programming language provides the system operator with flexibility for creation of new and unique control strategies. II is easily applied to a wide variety of mechanical including those that are application specific. Through Personal System Interface (PSITM) and Xtended Personal Interface (XPSITM), control programs can be downloaded all devices requiring the sequence of operation. With the MZII, I/A Series provides the best of both worlds; full for easy creation and modification of custom strategies, and easy duplication of controller databases for equipment containing similar or identical control MZII utilizes state-of-the-art, surface mount technology which reduce the size and cost of the product while providing product features. Modularity of hardware along with the capabilities allow easy expandability as the needs of facility change in the future. As with all other programmable Series controllers, the MZII utilizes non-volatile EEPROM to store application control programs. EEPROM memory an owner to modify existing control sequences or create ones through the Personal System Interface (PSI). Complete user creation of custom control strategies through programming structure adapts MZII to virtually any HVAC sequence or mechanical system. Models with battery backed-up time clock provide true direct digital control with optimum start stop, functions, and battery backed-up random access (RAM). Input/output auto trending with adjustable sample rates accumulate and time stamp last 48 analog values last 10 digital changes of state. Satellite point command capability from global controllers of unused points. half (0.5) second input to output response times make directly applicable to static pressure, fume hood and pressurization applications.
