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 Building
