GEN III – VVT is a commercial modulating zone control system controlling 2-20 independent zones per unit
utilizing wireless Zonex thermostats. The GEN III controller is designed for Auto Changeover, multi-stage Heat
Pump (2C/3H) or Gas Electric (2C/2H) applications.
Sophisticated, integrated software in the wireless thermostat allows for a wide range of system control and
changeover strategies, allowing the contractor to tailor the GEN III system to a specific application.
Additional features include LED status indication of all system functions, digital leaving air temperature, return
air temperature and outside air temperature display, fully adjustable capacity control with on-board limit
settings and optional staging strategies. An integrated clock allows for setup and night setback scheduling,
globally or individually available for each wireless thermostat, with selectable 2 to 8 hour override, along with
a unique feature to remotely lock each thermostat independently in the system.
The system provides the installing contractor with a simple startup diagnostic to minimize wiring errors and
speed installation.
GEN III is recognized as the Industry's easiest zone control system to install and wire. The GEN III System
operates over an unshielded-two-wire data link, along with two 24 VAC power wires all daisy chained from
damper to damper with no home run wiring required. Wireless thermostats do not require hardwire power or
wiring between the thermostats and dampers. Each Wireless thermostat is synced with its corresponding
modulating damper providing effective temperature control throughout the system.

GEN III– VVT
SEQUENCE OF OPERATION
Vote Based Auto Changeover Bypass VAV with Programmable Wireless Thermostats
GEN III controller wires to the HVAC unit with legacy style connections Y1, Y2, W1, W2, OB, G, R. Once every
minute the controller communicates to each damper via RS485 connection daisy chained along with 24 V of power
wired damper to damper. Each damper is equipped with a damper board ID and synced to its wireless
programmable thermostat, installed within 100 feet of the communicating damper board in the system.
The GEN III is an auto changeover, vote based VVT system. As thermostats call for heating or cooling, votes are
tallied at the GEN III controller; and, based on the majority of votes received, the HVAC unit operates in the mode
of majority votes. If majority changes, the system controller will automatically initiate a changeover sequence with
built in time delays to protect the equipment before changing over to the new mode of operation.
When the last calling zone is satisfied in either heat or cool mode, the GEN III controller will terminate the HVAC
outputs after the next “poll”; and the blower output will be de-energized (unless controller is configured for
constant fan) after a 4-minute purge cycle. During the purge cycle no heat or cool calls are recognized.
The wireless zone thermostats control and modulate the zone dampers based on variance from set point to a
position that will match the supply load to the demand requirement. When the HVAC unit is running, if a zone
thermostat is not calling or is calling for the opposite mode, its corresponding damper fully closes. When the
HVAC unit is not running, the thermostats open to the Vent mode to provide ventilation, if the indoor blower fan is
running continuously.
While the HVAC unit is running, the capacity control LAT device monitors the leaving air temperature from the
HVAC unit and will cycle the HVAC unit to maintain the air temperature with a preset range to eliminate coil
freeze-up and premature heat exchanger failure. When the system is in the heating mode and a majority vote
changes to cooling, a changeover timer begins and will run heating for 5 minutes or until heat call is satisfied and
then cycle into a changeover purge. After a 4-minute purge cycle, Cooling is turned on until the cool call is satisfied
or there is a majority vote for heat received by the GEN III controller. If all calls have been satisfied, after the 4
minute off delay, dampers will modulate to approximately 40% open position for ventilation mode.
The system fan/blower operation can be configured for ON or intermittent AUTO operation. The controllers are
shipped from the factory for Auto fan operation. The only time the fan will run is when there is a call from the
controller for heating or cooling. If the system is configured for fan ON operation, the fan will run continuously
during occupied time and intermittently during unoccupied time.
All zone thermostats are synced or paired with its respective modulating zone damper, which is equipped with
antenna and communicating damper board. One zone thermostat in the system shall be enabled as the Monitor
thermostat and synced with the GEN III controller to interact and initiate control decisions for the system. The
Monitor shall establish global or individual schedules for the system, lock thermostats individually and provide
minimal local adjustment, establish master temperature settings individually or globally for the system, and
provide diagnostic functions to streamline system troubleshooting. Air balance shortcuts, along with password
protection, are also enabled at the Monitor thermostat. Sleep and energy saving modes are available to extend
battery life and enhance operation.
Voting demand strategy can be enhanced by adding Priority votes or by giving a NULL vote to individual
thermostats in the system, thereby weighting certain zones more than others. Priority votes allow you to select 0, 1,
2, or 3 additional votes for a thermostat that has unusual loads, like a conference room. A change to 0 for priority in
that zone stat configuration will create a NULL vote for HEAT/COOL and will not allow the stat to place a call for heat
or cool, but will allow damper operation based on system mode of operation, HEAT/COOL/VENT.
The GEN III provides effective temperature control and minimizes wiring issues by using wireless programmable
zone thermostats. No computer or software tools are required for installation, commissioning or servicing the
system.

GEN III CONTROLLER
Controller Description
The GEN III is a micro-controller based, auto
change-over Universal Gas/Electric or Heat Pump
system controller (Part #GEN III ). The GEN III controls a
zoned 2H/2C Gas/Electric HVAC unit or 3H/2C zoned
Heat Pump unit and communicates with and supports up
to 20 zones, utilizing pressure dependent, modulating
dampers and wireless thermostats. The GEN III gathers
information every 60 seconds from each damper board
while the wireless thermostats communicate with
decisions to the HVAC equipment. The GEN III is powered with one 24 V 40VA transformer, which also
powers all dampers in the system. Power from the controller, along with a two-wire twisted pair
communications loop, is daisy chained damper to damper to streamline installation and system
communications. The GEN III is equipped with integrated capacity control and High and Low temperature
limits
to protect the compressor and heat exchanger. Outside air and return air sensors are also provided.
The HVAC unit is staged based on leaving air temperature and time. Auto change-over operation is vote
based, predicated on a first call, first served majority wins on changeover algorithm. Additional control
strategies are established on a Monitor Thermostat which initiates control decisions with the GEN III system
controller. Review controller terminal connections on the exhibit below:

ACTUATOR
COMMUNICATING DAMPER BOARD
A damper board resides on each zone damper to carry power and communications information from the
damper to the GEN III controller. The damper control board has four LED lights providing damper and system
information.
The BLUE LED (R) confirms communications and to sync the damper with its associated thermostat.
The RED LED (U) is illuminated when the damper is modulating to the closed position.
The GREEN LED (T) is illuminated when the damper is modulating to the open position.
The YELLOW LED (S) is illuminated when AUX heating is calling.
Once all dampers and the GEN III controller are wired into the system and the GEN III controller is turned ON,
the BLUE light will flash 4 times when communicating with the GEN III controller, and 2 times when the
damper control board communicates with the wireless thermostat.
The damper control board can be removed by slipping the mount away from the damper hat section,
simplifying wiring from the GEN III controller and AUX heat if utilized.
Each damper control board must be synced with its respective thermostat. Once the damper is energized
and associated thermostat has its ID set, press the ID button on the damper control board until blue light
flashes continuously and then press the YES button on the wireless thermostat which will display
“SYNC SUCCESSFUL”.

GEN III WIRELESS THERMOSTAT
WSTAT – Wireless GEN III Modulating Thermostat
The WSTAT wireless thermostat is used in conjunction with the modulating damper to communicate calls for
HEAT/COOL/VENT to the GEN III controller. Once the wireless thermostat is synced with its damper, the
thermostat is polled each minute and sends information to the communicating damper board and then to
GEN III controller. GEN III controller evaluates the information and determines if a majority of calls are for
HEAT or COOL, or if no calls are present VENT Mode.
To turn the wireless stat on, press and hold the AUTO/OFF button for 15 seconds. When OFF is displayed, press
and hold OFF button for 15 seconds until AUTO is displayed, release button, stat is in AUTO mode. If AUTO is
displayed press AUTO button for 15 seconds until OFF is displayed, release button, stat is in OFF mode.
Note: Mount wireless thermostat within 100 feet of the communicating damper board
Sequence of operation
COOL CALL
When zone temperature rises 1 or more degrees above COOL set point, thermostat transmits COOL call to
communicating damper board and GEN III controller. GEN III controller evaluates calls for HEAT and COOL
for majority vote. If there is a majority vote for COOL, GEN III controller initiates a call for cooling and the
damper modulates open. ON will be displayed and will flash until system is operating in the COOL mode.
Once system is in COOL mode, ON will remain constant. When zone temperature lowers to COOL set point,
COOL call is terminated and damper closes.
HEAT CALL
When the zone temperature falls greater than 1 degree below HEAT set point, thermostat will initiate a call
for HEAT. On the next poll, wireless thermostat will transmit HEAT call to the communicating damper board
and GEN III controller. GEN III controller will evaluate all calls for HEAT and COOL in the system and if there
is a majority of calls for HEAT, GEN III controller will initiate heat call and ON icon will appear below the set point. ON icon will flash until system is operating in the HEAT mode. Once system is in the HEAT mode, ON
will remain constant. Damper will modulate open and warm air will heat zone. As zone warms, thermostat
will communicate with damper relay and damper will modulate to maintain zone comfort. When zone
temperature rises to set point, damper is closed or at minimum position and WSTAT releases call for HEAT.
Baseboard HEAT
When wireless thermostat is configured for BASEBOARD heat, when zone temperature falls greater than 2
degrees below HEAT set point, AUX is energized and BASEBOARD heat is operating, ON will be displayed.
When zone temperature rises to HEAT set point, thermostat will release call for AUX operations.
REHEAT
When wireless thermostat is configured for REHEAT operation, when the zone temperature falls greater than
2 degrees below HEAT set point, thermostat transmits REHEAT call to the communicating damper board to
modulate damper to 40% open and energizes AUX output, ON will be displayed. When zone temperature
rises to HEAT set point, thermostat satisfies, releases call for AUX REHEAT and closes damper.
VENT
When all calls for HEAT or COOL are satisfied, dampers will modulate to approx. 40% open and VENT will be
displayed on thermostat indicating system is in ventilation mode.

Dampers
Install dampers into HVAC duct so damper actuators and control boards are easily accessed. Damper
may be mounted in an area where the ambient temperature is between 32 and 125 degrees Fahrenheit.
Round dampers should be mounted with damper actuators between 9 and 3 O’clock position.
Once GEN III controller and supply dampers are installed, install 24 VAC 40 VA transformer and wire
secondary 24 volts to the C R (IN - D) terminals on GEN III controller. Using 18 ga. thermostat wire, wire C
R (OUT - E) terminals and daisy chain power wires to the first damper. Continue daisy chain wiring from
first damper to second, third, etc., until all supply dampers are wired with power.
Note: Maintain R and C wiring polarity throughout the system to improve communications.
Once power wiring is daisy chained to all supply dampers in the system, use Belden 8740 twisted pair
communications wire to install communications loop. Install communications wire using the RX and TX
(G) terminals on GEN III controller and daisy chain to the first supply damper in the system and wire to RX
TX terminals of the communication damper board. Continue daisy chain to the next damper using RX TX
terminals of communication damper board to the RX TX of the next damper control board, repeating this
process until all supply dampers are wired into the communications loop. Communications wiring is
polarity specific, if RED communications wire is on RX at the GEN III controller, then RED wire is connected
to RX throughout the system.

Battery Installation/Replacement
Wireless Thermostat requires two AA batteries. Expected life with thermostat in active operation is 8-9
months or longer based on end user interaction. An energy savings mode is available to prolong battery life
to a year or more. Refer to Zone setup, menu item D for energy saving mode setup. To access batteries,
locate set screw on the bottom of the thermostat. Turn screw clockwise - this will cause the screw to move
into stat sub-base. Once set screw is free of GEN III stat, remove stat from sub-base. Remove batteries from
the back of thermostat and insert replacement batteries; ensuring positive and negative poles match battery
to thermostat. Place thermostat on sub-base and turn set screw counter clockwise to fasten thermostat to

THERMOSTAT OVERVIEW
AND OPERATION
WIRELESS PROGRAMMABLE THERMOSTAT
DESCRIPTION
The WSTAT wireless thermostat is a microprocessor based, auto
changeover, programmable communicating zone thermostat. The
zone thermostat controls modulating round or rectangular
commercial modulating dampers. The communicating zone
thermostat is used with the GEN III-VVT zoning system and
communicates over a proprietary wireless network protocol, with up
to 100’ transmission range.
The wireless zone thermostats control and modulate zone dampers
based on variance from set point to a position that will match the
supply load to the demand requirement. When the HVAC unit is running, if a zone thermostat is not calling
or is calling for the opposite mode, its corresponding damper fully closes. When the HVAC unit is not
running, the thermostats open to the Vent mode to provide ventilation, if the indoor blower fan is running
continuously.
All zone thermostats are synced with its respective modulating zone damper, which is equipped with antenna
and communicating damper board. One zone thermostat in the system is enabled as the Monitor thermostat
and synced with the GEN III controller to interact and initiate control decisions for the system. The Monitor
coordinates global or individual schedules for the system, locks thermostats individually and provides
minimal local adjustment, establishes master temperature settings individually or globally for the system, and
provides diagnostic functions to streamline system troubleshooting. Air balance shortcuts, along with
password protection, are also enabled at the Monitor thermostat. Sleep and Energy Saving modes are
available to extend battery life and enhance operation.
Each wireless zone thermostat is synced or paired with its
corresponding zone damper. Each thermostat communicates
wirelessly and modulates the damper based on variance from
set point at the stat.
During normal operation the Wireless Zone Stat is in the sleep
mode to extend battery life. It is operating and communicating
in the background, but sleep mode or energy saving mode will
significantly extend battery life.

is set, ON icon will appear below set point. ON icon will flash until system is operating in COOL mode. Once
system is in cooling mode, ON will remain constant.
Heat Call
If heating is desired, set HEAT set point 1 or more degrees above room temperature. Once desired temperature
is set, ON icon will appear below set point. ON icon will flash until system is operating in HEAT mode. Once
system is in heating mode, ON will remain constant.
Vent Mode
When all calls for heating and cooling are satisfied, damper controller will set the damper into VENT position and
report to the thermostat VENT operations. During this time if GEN III controller is configured for FAN ON,
recirculating air will be circulated to all zones.
Lock Thermostats
This is done at the MONITOR STAT, SYSTEM CONFIGURATION MENU Contact building manager for advanced
configuration
Override
To override thermostat operations when in the Unoccupied mode, press the AUTO button once and system will
run in the Occupied mode for configured override time. System will terminate override after configured run time,
if scheduled changeover occurs, or if AUTO button is pressed again.

WIRELESS REMOTE SENSOR
Description
The wireless remote sensor part # WRS is a microprocessor based, auto
changeover, programmable communicating zone thermostat without a
local display. The zone sensor controls modulating round, rectangular
dampers or WD-Fusers. The communicating remote sensor is used with the
GEN III-VVT zoning system.
The wireless remote sensor controls and modulates zone dampers based on
variance from set point to a position that will match the supply load to the
demand requirement. When the HVAC unit is running, if a remote sensor is
not calling or is calling for the opposite mode, its corresponding damper
fully closes. When the HVAC unit is not running, the remote sensor will
instruct its corresponding damper to go into Vent mode to provide
ventilation, if the indoor blower fan is running continuously.
The Remote Sensor provides local adjustment of +/- 2 degrees from set
point using the sensors slide pot. Auxiliary or supplemental heat sources,
i.e. base board, radiant panels, or reheat coils may also be controlled and
energized from each remote sensor if required.
Use a Monitor thermostat to set and review one or more remote sensors.
Sensor can be setup with daily schedules, priority votes and override
functions which are all programmed to the remote sensor from the Monitor
thermostat.
A Wireless Occupancy Remote Sensor is also available, and when it detects
a first body movement it will quickly blink the LED and read the slide pot.

WD-Fuser Zone Damper
Zonex Systems D-Fuser is a combination zone damper and diffuser. It mounts in a
standard 2’ x 2’ T-bar ceiling opening, providing for simple installation and easy
maintenance access. The D-Fuser is a cone shaped fluidic nozzle with a platen that
modulates up and down to control air flow. As the platen moves up, the air volume is
reduced; but the air velocity and throw remain constant. This keeps the air hugging
the ceiling, which maximizes room air mixing and minimizes the “waterfall” effect.
The damper is equipped with a damper board designed to support and
communicate with a Zonex wireless programmable thermostat. The D-Fuser is a fully
modulating power open / power close damper using a 24vac 60Hz 2 VA motor.
Up to three dampers can be directly controlled by one GEN III damper control board. The first damper must be a WST
round or WCD rectangular damper, slave dampers will be STMPD round or STCD rectangular dampers without damper
control boards. To wire two or three dampers for a zone, use the following wiring diagram. Remember to size the power
transformer for the total number of zone dampers in the system, 2VA per damper

BYPASS DAMPERS – ELECTRONIC
Electronic Bypass Dampers
Bypass dampers are used to provide constant air delivery through the air handling unit. This is done by
bypassing excess air from the supply duct back to the return duct. As a zone is satisfied, its zone damper
closes. When this happens, the bypass damper opens just enough to bypass the excess air. This will control
static pressure and noise at the diffusers.
Sizing Electronic Bypass Dampers
The bypass damper is to be sized for the total
system CFM @ 1500 FPM. System CFM should be
calculated at 400 CFM per ton.
Example: A 5-ton system is rated at 2000 CFM
(5x400 = 2000). When calculated at 1500 FPM,
the bypass damper should be 16”.
Never undersize the bypass damper.
Round Bypass Damper Selection
The Zonex Systems STBP damper is used for
round bypass applications. When you know the
bypass CFM requirements, use the ROUND
BYPASS SELECTION TABLE to confirm the round
damper size.
NOTE: Multiple round dampers can be slaved
from one sta
correct capacity. One large rectangular bypass
damper may be used instead of multiple round
dampers. See below.

ST BP16 16 16” 18” 19”
ST BP18 18 18” 20” 21”
Rectangular Bypass Damper Selection
The Zonex Systems STCDBP WxH damper is
used for rectangular bypass applications. These
dampers are also sized for the total system CFM
rated at 1500 FPM. Multiple dampers can be
slaved from a single static pressure control.
Bypass air in CFM. Calculated at 1500 FPM.
Formula used: B = W x H / 144 x 1500, where B = Bypass air in CF
144 = 144 sq. inches per sq. ft., 1500 = 1500 FPM.
M, W = damper width in inches, H = damper height in inches,

Slaving Bypass Dampers
Use only one Pressure Sensor when slaving two or
more Bypass Dampers together. Connect the
Pressure Sensor to one damper as described above.
Connect the slave dampers in parallel as shown. Up
to 4 dampers can be slaved to one Sensor. The
slaved dampers will self-synchronize each time the
dampers reach full open or full close.

BYPASS DAMPER WITH INTEGRATED PRESSURE CONTROL
(Part # STBP or STCDBP)
Bypass Damper with Integrated Pressure Control is used to control bypass operations. The bypass
damper modulates to maintain static pressure as zone dampers open and close. The bypass system
reduces air noise from the supply registers caused by excessive air velocity. If the system is configured
for intermittent fan mode and the system satisfies, there will be a 3-minute delay to allow for system
purge, after which the bypass damper will open to 25%, preventing noisy rush of air th
registers when fan starts up on a call for heat or cool. If the system is configured for fan continuous
operation, the STBP (Round) or STCDBP (Rectangular) Electronic Bypass will monitor static pressure
continuously, providing constant control of system static.

Bypass Damper Installation
1.
Verify the bypass damper is sized properly to
the system and not undersized. (Bypass damper
sizing is recommended for 100% of system
CFM.)
2.
Bypass damper and controller are powered by a
dedicated 24vac 40VA transformer.
3.
Do not install the bypass damper outside.
4.
Locate the Integrated Pressure Control (IPC)
and air tube on the bypass damper.
5.
Drill hole into the side of the supply duct 2’ after
the bypass and before the 1st supply take-off.
Mount pressure supporting block over hole,
align hole in block with hole in duct. Use
provided sheet metal screws.
6.
Install air tube into supply air duct by slipping
supplied plastic tubing into holes in support
block and duct. Slip
Pickup tubing fits snugly into provided hole.

Static Pressure Option: The Integrated
Pressure Control Board can be field
configured for specified static pressure using a
multi meter and the static pressure – voltage
chart. (Exhibit A). This chart shows voltage (DC)
to inches of W.C. (static pressure) relationship.
Use a multi meter set on VDC and place the
leads on the “C” terminal and “TP1” (test point
one) next to the potentiometer. The Voltage
reading translates to inches of W.C.

1.
Make cool call at the zone thermostat of the
smallest zone.
2.
Verify all zone dampers are closed except for
calling zone.
3.
Verify noise at zone registers is not excessive.
Adjust the Integrated Pressure Control LEFT to
lower noise (airflow) or RIGHT to increase
airflow until too noisy.
