The Auto-Zone Controls System was created from the original EZ Zone Control System concept by redesigning, enhancing and expanding the original systems capabilities under the new Auto-Zone Controls System name. WattMaster's Auto-Zone Control Systems have continued in the York EZ Zone tradition of keeping the controls simple to install and use while enhancing the system to make it more applicable and in line with the needs of the current marketplace. In addition to offering an excellent control system for zoning applications, the Auto-Zone Control System has been expanded to allow control of multiple single zone constant volume units and other devices such as lighting, exhaust fans, and unit heaters. Upgrading your EZ Zone system to the Auto-Zone Controls system allows you and your customer to take advantage of the many improvements that have been made in the Auto-Zone Controls system without having to replace all the EZ Zone system components that are installed on your job. This guide is intended to provide you with simple instructions on upgrading an existing EZ Zone system to an Auto-Zone Control System.

The York International Corporation's EZ Zone Controls System was first introduced in the early nineties. The EZ Zone Controls System was designed for York, by WattMaster Controls, as a simple zone control system for York's line of commercial unitary roof top and split system HVAC units. Since its original design and introduction, the York EZ Zone Control System has changed very little.

EZ Zone/Auto-Zone
EZ Zone Upgrade Overview
The basic steps required to upgrade your EZ Zone system to an Auto-Zone system are:
Determine what EZ Zone components are currently installed on the system. Replace the existing EZ-Zone Master Controller board with an Auto-Zone Zone Manager controller board Replace the existing EZ Zone EPROM's in each Zone Controller with a new Auto-Zone EPROM. Install return air and outside air temperature sensors
After upgrading your system from EZ Zone to Auto-Zone, you will be able to take advantage of many new enhancements including:
Damper actuators can be programmed for direct or reverse operation Full modulating economizer control capability including optional wetbulb economizer control Outside air temperature sensor provides lockout function for both heating and cooling. When converted to Auto-Zone Plus system only one outside air sensor is required for the entire system Contact closure input for dirty filter status Global and individual zone override modes Zones can be set for voting or nonvoting status Room sensor slide can be programmed ± 0° F to ± 5° F adjustment from setpoint Staging delays, minimum off times, and changeover intervals are programmable Sensor offset calibration to correct sensor errors due to poor location ZoneView enhanced graphical computer front end software available when CommLink and a PC are used System Manager operator interface allows all controllers to be accessed from one central location
EZ Zone to Auto-Zone upgrade allows you to retain:
All existing wiring Master Controller enclosure with keypad and display Existing supply air and static pressure sensors Existing bypass damper All Zone Dampers * All Zone Controllers Room sensors * Modem Link Central * All Master Interface Boards All Fan Terminal Controllers
* These controllers can be retained but they will require an EPROM chip upgrade to be compatible with the Auto-Zone System.

EZ Zone/Auto-Zone
Component Descriptions
The general architecture of the EZ Zone and the AutoZone Systems are very similar making the upgrade process relatively easy. There are some changes in the component descriptions between the EZ Zone system and the Auto-Zone system. It is important to understand these differences before you begin the upgrade process. Many of these components look similar, however, in some cases they do not function in an identical fashion. Having the wrong component installed can cause improper system operation. The chart below depicts the difference in descriptions for the various comparable system components in the EZ Zone and Auto-Zone Systems.

EZ Zone/Auto-Zone
Example #1:
Your project has a single EZ Zone Master Panel and it's associated Zone Controllers. This is a typical EZ Zone system. The upgrade will essentially convert this to an Auto-Zone Basic System. Please see the required upgrade components to be ordered in the list below. To upgrade your existing EZ Zone System to the AutoZone Basic System the following procedure will be required. Warning: All removal and installation procedures must be done with the power to the controllers turned off. Failure to do so can cause severe damage to the controller boards. 1) All power and input/output wiring will need to be disconnected from the board. Remove the enclosure cover and disconnect the keypad & display cable by unplugging the cable connector at the board connection. 2) The new Return Air Sensor should be installed in the return air stream in a location upstream of the point that the bypass duct connects to the return duct. 3) Install the new Outdoor Air Sensor in a location on the exterior of the building that provides shade and protection from the weather. See the mounting instructions included with the sensor for detailed mounting instructions. 4) Remove the existing EZ Zone Master Controller Board from the EZ Zone enclosure. This will require the removal of 4 screws securing the board to the enclosure base. 5) Install the new Zone Manager board onto the existing enclosure base. The new board installation requires 6 plastic standoffs be inserted between the back of the new board and the existing standoffs. Secure the board to 4 of the threaded standoffs (one in each corner of the board) with the mounting screws provided. 6) Connect the input, output and power wiring per the Auto-Zone Basic wiring diagram (See Figure 2 on page 17). Connect the keypad display connector of the existing EZ Zone enclosure cover to the new Auto-Zone Zone Manager board and secure the existing enclosure cover to the enclosure base with the existing screws. 7) Remove and replace each EPROM on all the existing EZ-Zone Zone Controllers. See Figures 16 & 17 on pages 28 & 29 for detailed EPROM Replacement information.
Note: When ordering be sure to specify Fahrenheit or Celsius operation for your system To Upgrade To The AZ Basic System Order the Following:
(1) (1) (X) (OE751) EZ Zone to Auto-Zone Basic Upgrade Kit (Includes: Zone Manager Board w/ Mounting Screws, Plastic Standoff Kit for Zone Manager, Return Air Sensor, Upgrade Label, Installation Instructions.

EPROM Installation Procedures
Gently Rock Chip Side To Side And Then Lift Straight Up To Remove Chip From Chip Socket.
WARNING!
Be sure the chip you have selected to replace is a socketed chip. Not all driver chips on the boards are field replaceable. Only socketed chips may be removed and replaced in the field. All other chips that are not socketed will require sending the board to the WattMaster factory for repair. If you try to remove a chip that is not socketed it will destroy the circuit board. Once you have determined that the chip needing replacement is indeed a socketed chip please proceed in the following manner.
Chip Chip Socket
I.C. Puller
Remove the communications loop connector and then the 24VAC power connector on the controller before attempting to change any components. DAMAGE will occur if components are removed or installed with power applied. If you are unsure how to safely remove the chip or about the correct pin placement, please consult the factory before proceeding. Damage to the board caused by failure to correctly remove or install the chip is not covered by the WattMaster warranty. Use extreme care to avoid inserting the screwdriver or I.C. Puller under the socket. You must insert the tip of the screwdriver or ends of the I.C. Puller between the body of the chip and the chip socket. Each chip MUST be installed with Pin 1 in the correct location. Installing the chip "backwards" will in most cases destroy the device when power is reapplied. Pin 1 can be located by looking for the notch in the end of the chip. Pin 1 on "some" chips is identified with a dot. Be certain that ALL pins are lined up in the socket before pressing the chip in. Failure to properly line up the pins will result in damage to the chip. This is a VERY common error - BE CAREFUL. Only after confirming that the chip has been correctly installed with Pin 1 in the proper position and that the pins are lined up and none are bent or out of the socket, should communication or power wiring be reconnected to the board. Tp prevent possible damage always reconnect the power wiring first and then the communication wiring.
Using I.C. Puller To Remove Socketed Chip
Printed Circuit Board
Gently Lift The Chip On One End And Rock Chip Back And Forth With Screwdriver As Shown. Repeat This Process On The Other End Of Chip. Alternate This Process On Both Ends Of Chip Until The Chip Is Free From The Chip Socket.
