INTRODUCTION

The Evolution Zone System consists of several intelligent communicating components which includes the Evolution Zone Control (or User Interface), Smart Sensors, Damper Control Module, variable- speed furnace or FE fan coil, 2-speed AC or HP, which continually communicate with each other via a four- wire connection called the ABCD bus. Commands, operating conditions, and other data are passed continually between components over the ABCD bus. The result is a new level of comfort, versatility, and simplicity.
All furnaces or fan coils are variable-speed and multi stage for maximum flexibility, efficiency, and comfort. They support controlled ventilation, humidification, dehumidification, and air quality control. Either a dual capacity (communicating), or a standard 24 vac controlled outdoor unit may be used. When using conventional outdoor units, the variable-speed furnace or fan coil provides the 24 volt signals needed to control them. Also, the Evolution™ Damper Control Module (P/N SYSTXBB4ZC01) allows connection of a conventional HRV or ERV without the need for a separate wall control.
All system components are controlled through the wall mounted Evolution™ Zone Control, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.

INSTALLATION AND START-UP OVERVIEW

This instruction covers installation of the Evolution™ Zone Control only. Physical installation instructions for the indoor and outdoor equipment, Damper Control Module, and accessories are provided with each unit.
Setup, commissioning, operation, and troubleshooting of the Evolution Zone System is covered only in this installation instruction.
It is the guide to connecting the system components and commissioning the system once all physical components are installed. Special screen prompts and start-up capabilities are provided in the Evolution System to simplify and automate the initial commissioning of the system.

• Install Evolution™ Zone Control according to this instruction.
• Install indoor unit, outdoor unit, and accessories according to their instructions.
• Wire complete system according to this instruction.
• Setup, commission, and operate system according to this instruction to assure a smooth and trouble free start-up.

INSTALLATION

A. Step 1 — Check Equipment and Job Site
INSPECT EQUIPMENT — File claim with shipping company, prior to installation, if shipment is damaged or incomplete.
B. Step 2 — Evolution Zone Control™ Location and Wiring Considerations
WARNING: ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or possible equipment damage.
Disconnect Power before routing control wiring.
All wiring must comply with national, local, and state codes. EVOLUTION™ ZONE CONTROL LOCATION— The Evolu- tion Zone Control™ User Interface is the command center for the Evolution Zone System and is typically located in Zone 1 to sense and control temperature in this zone. It should be located where it is easily accessible and visible to the adult homeowner or end user.
For accurate temperature measurement, the following guidelines should be followed:
The Evolution™ Zone Control and Room Sensors should be mounted:

• Approximately 5 feet (1.5 meters) from the floor.
• Close to or in a frequently used room, preferably on an inside partitioning wall.
• On a section of wall without pipes or ductwork. The Evolution™ Zone Control and Room Sensors should NOT be mounted:
• Close to a window, on an outside wall, or next to a door leading  to the outside.
• Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false  reading.
• Close to or in direct airflow from supply registers.
• In areas with poor air circulation, such as behind a door or in an alcove.

REMOTE ROOM SENSOR OPTION — A remote room sensor can be used with the Evolution™ Zone Control to take the place of the User Interface internal temperature sensor. This allows the Evolution™ Zone Control to be mounted in areas with less than
optimal airflow (such as near an exterior door, window or in a closet). The remote sensor can be wired to the terminal block connectors labeled S1 and S2 at the User Interface backplate, or the OS1 and OS1C connection at the Damper Control Module. In either case, the Evolution Zone Control will automatically detect the remote room sensor and ignore its internal temperature sensor.
It is also important to note the humidity sensor cannot be remotely located, so do not locate the Evolution Zone Control in an area where humidity sensing may not be accurate.
NOTE: S1 & S2 connection on UI backplate is now used for Remote Room Sensor, NOT for OAT Sensor hookup.
In addition, the Remote Room Sensor is a temperature sensor only, having no additional user inputs. This sensor is typically connected to the Damper Control Module and used to sense and control temperature in each zone.
SMART SENSOR — Any zone may use a Smart Sensor. It provides a temperature display and buttons to adjust the desired temperature in that zone only. It also displays outdoor temperature and indoor humidity. If a Smart Sensor is used in a zone, a Remote  Room Sensor may also be used in the same zone. The Remote Room Sensor has priority over the Smart Sensor.
WIRING CONSIDERATIONS — Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal wiring applications. Continuous wire lengths over 100 ft. should use 20 AWG or larger.
NOTE: ABCD bus wiring only requires a four-wire connection; however, it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation.
Each communicating device in the Evolution Zone System has a four-pin connector labeled ABCD. It is recommended that the following color code be used when wiring each device:
A — Green = Data A
B — Yellow = Data B
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)
It is not mandatory that the above color code be used, but each ABCD connector in the system MUST be wired consistently.
LOCATING DAMPER CONTROL MODULE — All wiring is run back to the Damper Control Module. Select a location near the furnace or fan coil where wiring from the User Interface, each Remote Room Sensor or Smart Sensor, each damper actuator, and the equipment itself can come together easily.
The Damper Control Module is approved for indoor use only and should never be installed with any of its components exposed to the elements. The Damper Control Module (and zone dampers) may be installed in any area where the temperature remains between -4°F. to 158° F. (-20°Cto70°C), and there is no condensation. The cover must be installed to prevent damage from other sources. Do not locate where it will be accessible to children.
It may be mounted in either vertical or horizontal position. Remember that wiring access is likely the most important consideration.
CAUTION: ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
To prevent possible damage to the Damper Control Module, DO NOT mount on plenum, ductwork, or flush against furnace or fan coil.
MOUNTING EVOLUTION™ ZONE CONTROL — There are two options for mounting the Evolution Zone Control™ to the wall. First, become familiar with all plastic assembly pieces shown in Fig. 2 through 9. The User Interface will snap together with either the Recess Mount or the Surface Mount backplate.
RECESS MOUNT — This provides the thinnest mounting configuration (See Fig. 3). The backplate containing the recessed terminal block can be mounted directly to the wall by cutting a hole 1 ½″ wide by 2 1/8″ high. Mark location and cut hole in wall.
NOTE: Always ensure the Evolution Zone Control™ location is acceptable before cutting any holes in wall.
SURFACE MOUNT — This provides surface mounting configuration, which allows use of a small hole in the wall. A surface mount backplate is supplied (See Fig. 4). Attach backplate as shown in Fig. 7, and the assembly will mount directly to the wall requiring only a small hole in the wall allowing a four wire connection to pass through.
NOTE: Once Evolution Zone Control™ is secured to wall with the backplate assembly (snapped together), care must be taken not to bend or break the interlocking tabs when removing. Gently remove Evolution Zone Control by rocking up/down until inter-locking tabs release.
DECORATIVE BACKPLATE — Supplied is a thin decorative backplate (see Fig. 5), to hide any marks/screw holes left from the previous thermostat. This decorative backplate (or beauty ring) can be used in either the recess or surface mount installation by snapping it onto back of recessed mount backplate or surface mount backplate before securing to wall. See Fig. 8 and 9 for a larger decorative backplate P/N SYSTXXOLBP01 (5.75″ wide X 6″ tall), which can be ordered separately. C. Step 3 — Installing Evolution Zone Control™
WARNING: ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing Evolution Zone Control™, turn off all power to equipment. There may be more than one power source to disconnect.

1. Turn off all power to equipment.

2. If an existing User Interface or control is being replaced:
   a. Remove existing control from wall.
   b. Disconnect wires from existing control.
   c. Discard or recycle old control.
   NOTE: Mercury is a hazardous waste, if existing control contains any mercury, it MUST be disposed of properly.

3. Select Evolution Zone Control™ mounting plastic (recess mount or surface mount and decorative backplate if desired).

4. Route wires through large hole in mounting plastic. Level rear plastic against wall (for aesthetic value only – Evolution Zone Control™ need not be level to operate properly) and mark wall through two mounting holes.

5. Drill two 3/16 inch mounting holes in wall where marked.

6. Secure mounting plastic to wall using two screws and anchors provided.

7. Adjust length and routing of each wire to reach each wire entry on the connector backplate. Strip ¼ inch of insulation from each wire.

8. Match and connect thermostat wires to proper terminals on User Interface backplate. See wiring diagram Fig. 12, 13, and 14.
   A — Green = Data A
   B — Yellow = Data B
   C — White = 24VAC (Com)
   D — Red = 24VAC (Hot)
   NOTE: It is not mandatory that the above color code be used, but each ABCD connection in the system MUST be wired consistently.
   A separate ABCD Connector comes inside packaging and should be used when connecting to furnace (or fan coil). Ensure connector is inserted properly into circuit board. (See Fig. 10) CAUTION: ELECTRICAL OPERATION HAZARD
   Failure to follow this caution may result in equipment damage or improper operation.
   Improper wiring of the ABCD connector will cause the Evolution Zone System to operate improperly. Check to make sure all wiring is correct before proceeding with installation or turning on power.

9. Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.

10. Attach Evolution Zone Control™ to the mounting plastic by lining up the plastic guides on the back of the control with the opening on the mounting plastic and push on.

11. Perform installation of all other system equipment (i.e. zone sensors, dampers, humidifier, ventilator, UV lights, etc.)

12.  Turn on power to equipment.

EQUIPMENT WIRING DIAGRAMS:

See wiring diagrams Fig. 12, 13, and 14 for connecting the Evolution Zone Control and Smart Sensors to the Damper Control Module. More information regarding Damper Control set-up and wiring can be found in Damper Control Module Installation Instructions.
See wiring diagram Fig. 12 which includes a variable-speed indoor communicating furnace or FE fan coil, with a 2-speed Puron™ communicating outdoor unit. No additional OAT (outdoor air temperature) sensor is required because the Evolution Zone Control will use the temperature sensor inside the 2-speed unit.
See wiring diagram Fig. 13 for connecting a variable-speed indoor communicating furnace or FE fan coil with a 1-speed air conditioning unit (non-communicating outdoor). An Outdoor Air Temperature (OAT) sensor may be installed (but is not required) at the indoor furnace or fan coil OAT terminals. When OAT sensor is applied, the Evolution System will provide enhanced system features and benefits.
See wiring diagram Fig. 14 for connecting an FE fan coil with a 1-speed heat pump (non-communicating outdoor unit). When OAT is applied, the Evolution system will provide enhanced system features and benefits.
NOTE: For other applications not listed, refer to the Network Interface Module (NIM) Installation Instructions. HUMIDIFIER CONNECTION — A 24vac bypass or fan powered humidifier may be installed.
NOTE: Do Not Use a traditional humidistat to control humidifier operation. If a humidifier is installed, let the Evolution™ Zone Control operate humidifier.
Bypass Humidifiers — A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24vac COM terminals.
The Evolution Zone Control will automatically energize the HUM output during a call for humidification.
Fan Powered Humidifiers — Most fan powered humidifiers produce internal 24vac in order to energize upon a switch or contact closure. For this application, a 24vac N.O. Isolation Relay (DPST) MUST be used to prevent mixing the internal humidifier power with the indoor equipment transformer. Applying 24vacisolation relay coil to furnace or fan coil HUM and COM terminals will allow the Evolution Zone Control to automatically energize the HUM output during a call for humidification. The N.O. relay contacts will be used to energize the humidifier. See fan powered
humidifier installation instructions for more details.
WARNING: FIRE OR EQUIPMENT HAZARD
Failure to follow this warning could result in equipment damage or fire.
Do not apply 24vac fan powered humidifier (with internal power supply) direct to indoor unit HUM and COM terminals.

Checkout = VENTILATOR
SPEED:

• OFF
• LOW
• HIGH

The ventilator can be exercised through all of its operating speeds
with this menu option.
Checkout = ZONING
DUCT ASSESSMENT
This is the same Duct Assessment that runs on first start-up.
Measures duct capacity for each zone. The Duct Assessment will perform an airflow measurement on each zone and determine the relative size of each zone along with damper leakage. This assessment will require approximately 1 minute for each zone in the system.
NOTE: A Duct Assessment will automatically occur every 24 hours at 1:00 p.m. to check system static and calibrate dampers.
SENSOR DAMPER CHECK:
The Sensor/Damper Check allows the installer to check each zone damper for operation, as well as insure the zone sensor corresponds to that particular zone.
When first initiated, the Zone 1 damper will fully OPEN, and all other zones will CLOSE. Using the scroll button, the installer can select each zone and verify the damper is fully open while all other dampers remain closed.
After proper damper operation has been verified, the installer can now check and verify that each remote room sensor corresponds to the proper zone damper in the same zone. Start from the top and highlight zone 1 to open damper. Temporarily disconnect any
other zone remote room sensor (at sensor location). That zone damper will now OPEN, while the Zone 1 damper will close.
EXAMPLE: If the Zone 2 remote room sensor is disconnected, the Zone 2 damper will now open as indicated on the User Interface display. The word ″FAIL″ will also be displayed instead of the actual temperature for Zone 2. Reconnect Zone 2 sensor and try all remaining sensors one at a time in the system. Smart Sensors may also be checked, see Smart Sensor Installation Instructions for procedure.
AIRFLOW LIMITS:

• Low
• Medium
• High (default)
• Maximum

Because there is no bypass damper, the Zone Airflow Limit check will allow the installer to assess the airflow noise generated by the system providing the maximum amount of airflow to each zone. Select 9 ZONE, then select AIRFLOW LIMIT: Low, Medium, High (default), or Maximum. When Start is pressed (right side button), the selected zone’s damper will fully open, all others will close, and the indoor unit will provide the maximum airflow for that zone (as selected in Setup = ZONING, Airflow Limits). If the airflow noise is objectionable, the installer can select a lower airflow noise limit. If the noise is not objectionable, the installer should leave High selected, or even Maximum.
NOTE: Selecting a lower airflow noise limit may decrease the homeowner’s comfort in that zone.
SERVICE MENUS
The Service Info menu will only show the equipment installed in the system. Below is a sample using a furnace and a heat pump (dual fuel). A sample service menu is shown in Fig. 25.![bryant SYSTXBB4ZC01 Evolution Zone Control

• Press top left ZONE button to select zones.

Continuous Fan Operation
Pressing FAN button will scroll through the following:

• AUTO = No fan operation except during equipment operation.
• LOW = Approximately 50% of High Speed operation.
• MED = Half way between High and Low speed operation.
• HIGH = Highest of either High Heating or High Cooling CFM.

Five-Minute Compressor Timeguard
This timer prevents compressor from starting unless it has been off for at least 5 minutes. It can be defeated by simultaneously pressing the Fan and Temp + buttons.
Emergency Heat (for heat pump applications)
To activate Emergency Heat, you must press and hold the HEAT button for 3 seconds to activate.
Keypad Lockout
Keypad can be locked by pressing ″Fan″ and ″Zone″ buttons at the same time for 3 seconds. When keys are locked, a lock symbol will appear in the upper left corner of screen. Follow same procedure to unlock keypad.
Heat and Cool LED
The Heat and Cool LEDs will pulsate during actual equipment operation.
Equipment Cycle Timer (adjustable 4-6 cycles per hour)
This timer prevents the start of a heating or cooling cycle until 15 (or 10) minutes after the last start of the same cycle. Its function is to assure that the equipment is not cycled more than the selected times per hour. This timer is adjustable from 4 to 6 cycles per hour.
This timer is defeated for one cycle when the desired temperature is manually changed. It can also be defeated for one cycle by simultaneously pressing the Fan and Temp + buttons.
Ten-Minute Staging Timer
In multistage heating or cooling, this timer prevents any higher stage from turning on until the preceding stage has been on for 10 minutes. This timer is defeated if temperature error is greater than 5°F (usually due to a large change in desired temperature).
Three-Minute Minimum On Time
In normal operation, when a stage turns on, it will remain on for a minimum of three minutes. If the set point is changed, this timer is automatically cancelled, allowing the equipment to turn off immediately when the demand is removed.
Heat/Cool Set points (Desired Temperatures)
A minimum difference of 2° (default) is enforced between heating and cooling desired temperatures. This is done by allowing one setting to ″push″ the other to maintain this difference. This difference is adjustable via the Install/Service menu under Thermostat
Setup.
Auto Changeover
When Auto mode is enabled (factory default) a change from heat to cool (or vice versa) will not occur until an opposite mode demand has existed for 30 minutes. If the set point is changed, the 30-minute requirement is defeated. This Auto Changeover time is adjustable via the Install/Service menu under Thermostat Setup.
Range=5-120min.
Smart Recovery
With Smart Recovery selected (factory default), transition out of setback begins 1.5 hours before selected recovery time and gradually adjusts room temperature so desired temperature will be achieved at selected recovery time. It operates in both heating and cooling. This only applies to programmable operation.
Media Filter
If MEDIA or MEDIA+EAC is installed in the indoor unit, the system will perform a static pressure check of the system every 24 hours at 1:00PM to monitor filter accumulation (TrueSense™ Dirty Filter Detection) or whenever power is applied to the system or the system is transitioned from Off to Cool or Heat modes. The blower will run at a medium airflow for one minute.
Unoccupied
Pressing the HOLD button for 3 sec. will set the selected zone to unoccupied status.
All Zones
Pressing the zone button for 3 sec. will gray out the entire display and put the User Interface into All Zones mode (indicated by All Zones in upper left of the display). Any changes to set temperature, fan, or Hold status will occur in all zones when the screen is exited. Press the Zone button to exit All Zones mode.

TROUBLESHOOTING

Evolution Zone Control™ does not power up.

1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Make sure power is applied to the indoor unit, and the amber LED is lit on indoor control circuit board.
4. Check for 24VAC between the C and D terminals at Evolution Zone Control™ terminal connector and Damper  Control Module.
5. Check fuse on indoor unit’s circuit board.

Display says ″Indoor Unit Not Found″

1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Press left-side button to try again.
4. If display still reads ″Indoor Unit Not Found″, disconnect all devices from ABCD and connect User Interface directly to indoor unit.
