Errors which can result in damage to equipment and void warranties Guide 1 Plus HVAC Unit 1 Panel Temp Temp By Others Temp Air Air Dampers to 16 Zone Air Dampers Allowed Loop Loop Baud Manager Link Temp Temp II Loop Air Air Dampers to 16 Zone Air Dampers Allowed Volume Units to 13 CV Units May Be added To Zone Manager Loop HVAC Unit 2 Panel Other Zone To 30 Per System Loop 1 1 Auto Zone Plus System Guide Plus 1 Information Auto Zone Plus control system converts single zone or Variable Air Volume rooftop HVAC units into variable air volume variable temperature multiple zone The microprocessor based Zone Manager MC calculates the heating and cooling for each zone based on real time information received from each Zone The Zone Manager MC then directs the HVAC unit to provide the appropriate of heating cooling and ventilation to satisfy each zone requirements A static air sensor modulates a bypass damper or controls the supply fan speed through a Frequency Drive VFD to maintain constant duct pressure Auto Zone Plus System Manager allows multiple Zone Managers to be programmed monitored from a central operator panel Single zone constant volume rooftop units can also be connected to the Auto Zone Plus communication network for both multizone and single zone equipment to be controlled from the same savings can be realized using the Auto Zone Plus system instead of having to multiple rooftop units to accommodate multiple zone requirements The Auto Zone system is versatile and can be used with any packaged roof top unit or split system It a variety of terminal unit functions including single duct pressure dependent or independent systems optional color graphics software package is available for on site or remote monitoring of System Components typical Auto Zone Plus system is comprised of the following basic components Manager microprocessor based System Manager allows multiple Zone Managers and any constant volume HVAC units to be programmed and monitored from a central panel The System Manager is connected via the Auto Zone Plus network System Manager is mounted in an attractive white plastic housing suitable for wall A four line by twenty character backlighted LCD display and membrane keypad a user friendly interface All system variables setpoints and values can be viewed modified from the System Manager Menu driven programming makes the Auto Zone easy to set up and operate without the need for specialized training Guide 1 Plus II CommLink II communications interface allows user access to any controller Locally is by means of an on site computer Remote access is obtained via modem The II may also be configured for Call Out on Alarm The CommLink II comes in an attractive plastic enclosure and is powered by a small wall mounted The CommLink II should be located near the computer which will be used to the system If no on site computer is to be used then locate the CommLink II near phone line jack if a modem is to be used The cables from the CommLink II to modem the CommLink II to computer should not exceed twenty five feet Manager MC Zone Manager MC is a microprocessor based controller which monitors up to zones in the system The zone manager then controls the HVAC unit to satisfy the of each individual zone while maintaining efficient operation and comfort Zone Manager MC operates the fan heating cooling duct static pressure and functions Each Zone Manager also features time scheduling night set back logging of sensor values and automatic changeover Damper or VFD Control bypass damper controls proper duct static pressure to insure proper air flow The is modulated by the Zone Manager MC based on a signal received from the static sensor connected to the main duct The VFD control sends a 0 10 vdc signal to variable frequency drive based on a signal received from the static pressure sensor to the main duct Controller Zone Controller monitors space temperature and allocates proper air flow to the zone to achieve desired comfort and ventilation levels If supply air temperature benefit the local zone temperature setpoint the zone damper modulates to reduce or air flow as needed If supply air will not benefit the local zone the controller will the damper actuator to a minimum position and wait for a change in supply air Volume Controller Constant Volume CV Controller is a microprocessor based controller designed to packaged roof top HVAC units Up to thirteen stand alone CV
