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

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.
Master Controller Zone Manager
Must Be Replaced Improved Hardware & Software
Fan Terminal
Controller
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.

Upgrade 7
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 pro-
tection 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) (OE751) EZ Zone to Auto-Zone Basic Upgrade Kit
(Includes: Zone Manager Board w/ Mounting Screws, Plastic Standoff Kit for Zone Manager,

EZ Zone/Auto-Zone
Example #2:
Your project has multiple EZ Zone Master Panels and
their associated Zone Controllers. This upgrade will
convert this to an Auto-Zone Plus System.
To upgrade your existing EZ Zone System to the AutoZone Plus System the following procedures 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 existing Master Controller board.
Disconnect the keypad & display cable from the board
by unplugging its connector from the board and the display on the existing enclosure cover.
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. Only one OA sensor is
required for the entire system. See the mounting instructions included with the sensor for detailed mounting
instructions.
4) Connect the CommLink to the network communica-
tions loop and wire in 24VAC power (See Figure 13 on
page 25).
5) Remove the existing EZ Zone Master Controller

Upgrade 11
EZ Zone/Auto-Zone
Example #3:
Your project has a Networked EZ Zone System that you
want to convert to the Auto-Zone Plus system. Please
see the required upgrade components list below for the
necessary parts to be ordered.
To upgrade your existing Networked EZ Zone System
to the Auto-Zone Plus System the following procedures
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 existing Master Controller board.
Disconnect the keypad & display cable from the board
by unplugging its connector from the board.
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. Only one OA sensor is
required for the entire system. See the mounting instructions included with the sensor for detailed mounting
instructions.
& 27 for detailed EPROM installation instructions.
5) 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. Remove the existing Master Interface
Board from the old Master Controller board. Remove
the old EPROM from the Master Interface board and
install the new MiniLink upgrade EPROM to the Master Interface board. See Figures 15 & 17 on pages 26 &
27 for detailed EPROM installation instructions.
6) Install the upgraded Master Interface board to the
new Zone Manager board using the existing mounting
hardware. Install the new Zone Manager board onto the
existing enclosure base. The new Zone Manager 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 screws that
were included with the new Zone Manager board.
7) Connect the input, output and power wiring per the
Auto-Zone Plus wiring diagram (See Figure 3 on page
18). Connect the existing 3 Connector Ribbon Cable
keypad display connector to the existing EZ Zone enclosure cover and to the new Auto-Zone Zone Manager
board (See Figure 18 on page 30). Secure the existing
enclosure cover to the enclosure base with the existing
screws.
4) Take the cover off of the Modem Link Central, remove the old EPROM and replace with the new
CommLink EPROM. See Figures 14 & 17 on pages 25
Note: When ordering be sure to specify Fahrenheit or Celsius operation for your system
To Upgrade To The Auto-Zone Plus System Order the Following:
(X) (OE751) EZ Zone to AZ Basic Upgrade Kit (One Required Per Existing Master Controller)
(Includes: Zone Manager Board w/ Mounting Screws, Plastic Standoff Kit for Zone Manager,
Return Air Sensor, Upgrade Label, Installation Instructions)
(1) (OE755) Modem Link Central to CommLink II Upgrade Kit
(Includes: ComLink EPROM Upgrade Chip, Upgrade Label)

EZ Zone/Auto-Zone
Optional Controllers and Accessories
In addition to the standard Zone Manager and Zone
Controllers, WattMaster offers many other controllers
and accessories to enhance your new Auto-Zone System. Optional Controllers that are available for use with
the Auto-Zone Plus system include the CV, CV-C, GPC,
Optimal Start Scheduler, Lighting Panel Controller and
Wetbulb Module. These controllers are not available
for use with the Auto-Zone Basic System. To utilize
any of the optional controllers you must upgrade your
system to the Auto-Zone Plus configuration. Accesso-
CV Controller
The CV Controller provides control of single zone constant volume rooftop or split system HVAC equipment.
CV controllers have four configurable relay outputs for
heating/cooling staging, a 0-10VDC output for economizer control, on board time clock for scheduling/night
setback functions and built in alarming features.
The CV Controller can be used with the Auto Zone
CV-C Controller
ries that are available for use with either the Auto-Zone
Plus or Basic System include the CommLink II Communications Interface, Remote Link, Room Sensors,
Round Zone Dampers and Rectangular Zone Dampers.
WattMaster also offers Communication Cable that is
color coded and labeled for the network communications loop and local communications loop.
Following are brief descriptions of the optional controllers and accessories that are available.
Plus System only. The CV can be programmed and
monitored from the either the System Manager or from
a personal computer which has the ZoneView Computer front end software installed. Up to 13 CV controllers can be installed on each local communications
loop of your Auto-Zone Plus system.
The CV-C Controller is a field configurable constant
volume unit controller that provides additional features
which are not available with the standard CV controller. CV-C controllers can be configured for applications
requiring CO2/IAQ economizer control, modulating HW
and CW control valves and dehumidification. The CVC relay outputs can be expanded via a plug-in expansion board for use in applications requiring additional
heating/cooling staging control.
GPC Controller
The GPC (General Purpose Controller) is a very versa-
tile controller that can be used for a variety of control
applications that are outside the function of our standard HVAC unit controllers. Each GPC controller has
(5) Universal Inputs that can accept contact closures,
thermistor temperature sensors, or 4-20mA/2-10VDC
signals. The controller has (5) digital outputs for on/off
control and (1) 0-10VDC analog output to modulate a
valve or damper. These inputs and outputs can be configured in a variety of ways using And/Or logic functions, time schedules, setpoints, etc. to perform many
different tasks.
The CV-C Controller can be used with the Auto-Zone
Plus System only. The System Manager cannot be used
to program or monitor the CV-C controller. CV-C controllers require that a personal computer which has the
ZoneView computer front end software installed be used
for all programming and monitoring. Up to 13 CV-C
controllers can be installed on each local communications loop of your Auto-Zone Plus system.
The GPC can be used for many applications including,
but not limited to:
• Control of Unit Heaters
• Control of Boilers
• Control of Exhaust Fans
• Monitoring of Temperature
• Monitoring of Humidity
• Monitoring of Status Contacts
The GPC Controller can be used with the Auto-Zone
Plus System only. The System Manager cannot be used
to program or monitor the GPC controller. GPC controllers require that a personal computer which has the
ZoneView computer front end software installed be used
for all programming and monitoring.
14 Upgrade
Lighting Panel Controller
EZ Zone/Auto-Zone
Adds building lighting control capability to the AutoZone System. The Lighting Panel Controller provides
up to (7) Independent time schedules and light levels
for control of up to (7) lighting circuits. The Lighting
Panel Controller relay outputs can be set for on/off relay or pulsed relay control depending on the lighting
system control contactor requirements. Pushbutton override is available for each lighting circuit by connecting
a momentary pushbutton to the Lighting Panel Controller board.
Optimal Start Scheduler
Provides expanded scheduling capabilities beyond those
incorporated with the standard Auto-Zone controllers.
The Optimal Start Scheduler provides for optimal
Start/Stop and up to (7) independent schedules with 2
Start/Stop events per day and (14) Start/Stop holiday
events per schedule.
Wetbulb Module
Provides wetbulb temperature monitoring for control
of all economizer equipped units on the Auto-Zone
system. The Wetbulb Module includes an Outside Air
Humidity Sensor for measuring outside air relative
humidity and utilizes the installed Outdoor Air Sensor
on the Auto-Zone System to calculate the wetbulb
temperature. This temperature is used by the economizer
control portion of the unit controller to provide accurate
The Lighting Panel Controller can be used with the Auto
Zone Plus System only. The System Manager cannot
be used to program or monitor the Lighting Panel Controller. Light Panel Controllers require that a personal
computer which has the ZoneView computer front end
software installed be used for all programming and
monitoring.
The Optimal Start Scheduler can be used with the Auto
Zone Plus System only. The System Manager cannot
be used to program or monitor the Optimal Start Scheduler Controller. This controller requires that a personal
computer which has the ZoneView computer front end
software installed be used for all programming and
monitoring.
economizer operation. The Wetbulb Module can be used
with the Auto-Zone Basic and Plus Zone Systems. The
Wetbulb Module can be monitored and programmed
from either the System Manager or from a personal
computer which has the ZoneView computer front end
software installed.

The Auto-Zone Plus Zone Manager has two different
address switches. One is located on the main Zone
Manager board and one is located on the MiniLink board
that is located on the top of the Zone Manager board.
The Zone Manager board address should always be set
to address 17 on an Auto-Zone Plus system. The
MiniLink board should be addressed with a unique number for each Zone Manager on the system. It is recommended that you start with address 1 and address each
Zone Manager consecutively. See Figure 4 below for
detailed information.

Zone Manager wiring is much simpler than the EZ Zone
Master Controller wiring. Be sure to pay strict attention to all warnings and cautions listed on the schematic.
The EZ Zone Master Controller relay outputs consist
of a series of five double pole
terminal blocks. Wire jumpers between terminal blocks
are required to the common
of each relay.

The EZ Zone Master Controller has two double pole
terminal blocks for the bypass actuator connections.
These terminal blocks must
be tied together by an external jumper. In addition, the
feedback connection from the
actuator must be terminated
on the other side of the controller .
The Auto-Zone Zone Manager wiring has been simplified. There is only one terminal block with connections
clearly marked for ease of
installation. The actuator
“feedback” connection is
now terminated at the same
location as all the connections. Jumpers are no longer
required since the commons
are tied together within the
circuit board.

Honeywell Economizer Actuators
EZ Zone/Auto-Zone
When the HVAC units that are being upgraded to
the Auto-Zone system are equipped with either the
Honeywell M7415 or M7405 economizer actuators, an interface module and a isolation transformer
are required in order to connect and use the economizer outputs on the Auto-Zone system. The interface module converts the Honeywell actuator from
0-5VDC operation to 0-10VDC operation. An isolation transformer is also required for this installation to prevent voltage feedback to the control system. The OE266-01 Actuator Interface Module kit

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.
remove a chip that is not socketed it will destroy
the circuit board.
chip needing replacement is indeed a socketed chip
please proceed in the following manner.
Remove the communications loop connector and
then the 24VAC power connector on the controller
before attempting to change any components.
DAMAGE
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 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 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 common error -
VERY 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.
