1. Safety Considerations
Improper installation, adjustment, alteration, service, maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause death, personal injury or property damage. Consult a qualified installer, service agency or your distributor or branch for information or assistance. The qualified installer or agency must use factory--authorized kits or accessories when modifying this HVAC system. Refer to the individual instructions packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing, and work gloves. Have a fire extinguisher available. Read these instructions thoroughly and follow all warnings and cautions included in literature and attached to the unit. Consult local building codes and the current edition of the National Electrical Code (NEC) NFPA 70. In Canada, refer to the current editions of the Canadian Electrical Code CSA C22.1.
Recognize safety information. When you see this symbol
on the unit and in
instructions or manuals, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING,andCAUTION. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards, which will result in severe personal injury or death. WARNING signifies hazards, which could result in personal injury or death. CAUTION is used to identify unsafe practices, which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.
2. Introduction
The Evolutionr System consists of several intelligent communicating components which include the Evolutionr Connext Control (or User Interface), variable speed furnace or FE fan coil, and 2--stage AC or HP, which continually communicate with each other via a four--wire connection called the ABCD bus. Commands, operating
2
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 Evolutionr 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 an Evolutionr (communicating), or a standard single--stage 24VAC controlled outdoor unit may be used.
When using a Bryant HRV or ERV with a zoned system, the Evolutionr Zone board allows connection of a Bryant HRV or ERV without the need for separate wall control.
When using conventional single--stage outdoor units, the Evolution furnace or fan coil provides the 24 volt signals needed to control them. Also, the Evolutionr Network Interface Module (P/N SYSTXBBNIM01) allows connection of a Bryant HRV or ERV without the need for separate wall control.
All system components are controlled through the wall mounted Evolution Connex Control, which replaces the conventional thermostat and provides the homeowner with a single wall control for all features of the system.

4. Installation
4.1. Overview
This instruction covers installation of the Evolutionr Connext Control and the Evolutionr Wireless Access Point only. Physical installation instructions for the indoor and outdoor equipment, and accessories are provided with each unit.
Setup, commissioning, operation, and troubleshooting of the Evolutionr System are 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.
S Install the Evolution Connex Control according to this instruction. S Install indoor unit, outdoor unit, and accessories according to their instructions. S Wire complete system according to this instruction. S Setup, commission, and operate system according to this instruction to assure a
smooth and trouble free start--up.
4.2. Check Equipment
Inspect equipment. File a claim with shipping company prior to installation if shipment is damaged or incomplete.
7
4.3. Location
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
Disconnect power before routing control wiring.
!
WARNING
All wiring must comply with national, local, and state codes.
4.3.1. Wall Control
The Evolution Connex Control is the command center for the Evolution System. 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 Connex Control and Remote Room Sensors SHOULD be mounted:
S Approximately 5--ft (1.5 m) from the floor. S Close to or in a frequently used room, preferably on an inside partitioning wall. S On a section of wall without pipes or ductwork.
The Evolution Connex Control and Remote Room Sensors SHOULD NOT be mounted:
S Close to a window, on an outside wall, or next to a door leading to the outside. S Exposed to direct light or heat from a lamp, sun, fireplace, or other
temperature--radiating objects which could cause a false reading.
8
S Close to or in direct airflow from supply registers. S In areas with poor air circulation, such as behind a door or in an alcove.
4.3.2. Remote Room Sensors
A Remote Room Sensor can be used with the Evolution Connex Control to take the place of the control’s internal temperature sensor. This allows the Evolution Connex 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 control’s backplate, or the ZS1 and ZS1C connection at the Damper Control Module. In either case, the Evolution Connex Control will automatically detect the Remote Room Sensor and ignore its internal temperature sensor.
4.3.2.1. Remote Room Sensor Averaging
Typically, one remote sensor is used but, multiple sensors may be used and averaged in some applications. Averaging requires a special series--parallel wiring method with a specific number of sensors. See figure below. It is also important to note the humidity sensor cannot be remotely located, so do not locate the Evolution Control in an area where humidity sensing may not be accurate.

4.3.3. Smart Sensors (for zoning applications)
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 sensed at the control. Only one Smart Sensor may be used per zone. They cannot be averaged like Remote Room Sensors. 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. The Smart Sensor will display the Remote Room Sensor temperature.
NOTE: Smart Sensors must be addressed to identify which zone it will control. See Smart Sensor Installation Instructions for details.
4.4. 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.
10
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 Evolutionr 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)
ABCD
A03193
It is not mandatory that the above color code be used, but each ABCD connector in the system MUST be wired consistently.
NOTE: Some outdoor units provide their own low--voltage power source and do not require the “C” (24VAC common) and “D” (24VAC power) connections. See the outdoor unit installation instructions for more information.
11
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing, modifying, or servicing system, the main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label.
!
WARNING
S Turn off all power to equipment. S If an existing Evolutionr Control or other control is being replaced:
d Remove existing control from wall. d Disconnect wires from existing control. d Discard or recycle old control.
S NOTE: Mercury is a hazardous waste, if existing control contains any
mercury, it MUST be disposed of properly. The Evolution Connex Control does not contain mercury.
S Select Evolution Control mounting plastic (backplate and decorative backplate
if desired).
S Route wires through large hole in mounting plastic. Level rear plastic against
wall (for aesthetic value only; Evolution Connex Control need not be level to operate properly) and mark wall through two mounting holes.
S Drill two 3/16--in (4.8 mm) mounting holes in wall where marked. S Secure mounting plastic to wall using two screws and anchors provided.
12
S Adjust length and routing of each wire to reach each wire entry on the
connector backplate. Strip 1/4--in (6.4 mm) of insulation from each wire.
S Match and connect thermostat wires to proper terminals on control backplate.
d See wiring diagrams in Appendix A.
S Push any excess wire into the wall. Seal hole in wall to prevent any air leaks.
Leaks can affect operation.
S Attach Evolution 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.
S Perform installation of all other system equipment (i.e. dampers, humidifier,
ventilator, UV lights, etc.).
S Turn on power to equipment.
4.4.1. Shielded Wire
If the thermostat wiring will be located near or in parallel with high voltage wiring, radio, TV or Ethernet wiring, then four conductor, twisted--pair, shielded cable can be used to reduce or eliminate potential interference. The shield wire should be connected to the C terminal, or ground, at the indoor unit. The shield wire should NOT be connected to any terminal at the user interface. Connecting the shield to ground at both ends can cause current loops in the shield, reducing shield effectiveness.
Connect one pair of the two--pair (minimum) cable to the A and B communication terminals, and another pair to the C and D terminals at both ends of the cable. The shield wire should ONLY be connected at the indoor equipment ground or C terminal. Note that some outdoor units only require the A and B connections. See the outdoor unit installation instructions for more information.
13
4.4.2. Damper Control Module (zoning systems only)
All zoning wiring is run back to the Damper Control Module. Select a location near the furnace or fan coil where wiring from the control, 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.
PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury. To prevent possible damage to the Damper Control Module,
DO NOT mount on plenum, ductwork, or flush against furnace or fan coil.
CAUTION
!
4.5. Mounting
First become familiar with all plastic assembly pieces shown on the following page. The Evolution Connex Control will snap together with the backplate. A backplate is supplied. Attach backplate using only a small hole in the wall allowing a four wire connection to pass through. Mount the assembly to the backplate.
14
A12214
A12215
NOTE: Once Evolution 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.
4.5.1. Decorative Backplate
Sold separately, a thin decorative backplate is available to hide any marks/screw holes left from the previous thermostat. This decorative backplate (or beauty ring) is used by snapping it onto the back of the mounting plate before securing the plate to the wall.
15
A12213
NOTE: Once the Evolution Connex 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.
4.6. Humidifier Connections
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 Connex Control operate humidifier.
4.6.1. Bypass Humidifier
A bypass humidifier should be wired directly to the furnace or fan coil HUM and 24VAC COM terminals. The Evolution Control Connex will automatically energize the HUM output during a call for humidification.
4.6.2. 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 24VAC isolation relay coil to furnace or fan coil HUM and COM terminals will allow the Evolution Connex Control to
16
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.
5. Commissioning
This section addresses initial power up (or commissioning) of a new Evolutionr Connex Control. The control will communicate and identify all components in the Evolutionr System. The following is a typical example for a communicating variable--speed furnace / fan coil with a 2--stage air--conditioner / heat pump (including Hybrid Heatr dual fuel system).
5.1. Searching for Indoor Unit
The Evolutionr Connex Control will light up and begin the commissioning process by displaying “Searching for indoor unit”. This includes Evolutionr small packaged products (SPP), with UI Version 8.0 software or later.
A12177
NOTE: If the Evolution--compatible indoor equipment (furnace or fan coil) cannot be found, the control will display “Indoor unit not found”. This MUST be corrected before the initial power up sequence can continue. Proceed to the next section, Searching for outdoor unit. If it is not corrected, the Evolution Connex Control will go into its DEMO operating mode.
17
A12178
5.2. Searching for Outdoor Unit
The Evolution Connex Control will then proceed to communicate with the outdoor unit by displaying “Searching for outdoor unit”. This includes Evolutionr small packaged products (SPP), with UI Version 8.0 software or later.
NOTE: If the outdoor unit cannot be found, the control will display “Outdoor unit not found”.
S Select the appropriate unit installed; then, touch NEXT.
d AC1Stage – 1--stage air conditioner d *AC2Stage – 2--stage air conditioner d *HP1Stage – 1--stage heat pump d *HP2Stage – 2--stage heat pump d None – No outdoor unit installed
NOTE: For small packaged products (SPP), the selection screen is not needed and will not appear.
S The installer will first be instructed to select the appropriate size of the outdoor
unit; then, touch SELECT.
*Network Interference Module (NIM) may be required for these selections to be displayed.
18
A13118
5.3. Indoor Evaporator Selection
If a furnace is installed with a variable capacity heat pump or an Evolution V heat pump, a screen will appear to select the installed indoor evaporator coil. This selection is used to adequately calculate the refrigerant charge required while in the heat pump charging screens under the Heat Pump Checkout menu (See Pg. 54). Select “other” for non--Bryant evaporators.
5.4. Electric Heater Selection
If the indoor equipment is a fan coil, the control will display “Searching for heater” until one is found. If the electric heater is not self--identifying, the select heater screen will appear. Touch the appropriate heater size; then, touch SELECT.
19
A13119
5.4.1. Hydronic Heat Application
The Evolution Connex Control supports 2 types of Hydronic Heat applications:
1. Hot water coil in combination with an FE fan coil and heat pump, or hot water coil as sole heat source with an FE fan coil.
2. Non--zoned FE fan coil combined with radiant hot water heat.
In either application, a Hydronic Heat kit should be installed in place of an electric heater. See FE fan coil Product Data for accessory part number. The system will self--identify that hydronic heat has been installed during electric heater selection. The system will treat the hot water coil as either auxiliary heat in a heat pump application, or the sole heat source. Setup options for Hydronic Heat applications are described in the setup section of this instruction.
20
A13117
5.5. Searching for SAM Module (If Applicable)
“Searching for SAM Module” will appear on the screen to determine if a System Access Module, used for home automation only, is connected to the system.
The SYSTXBBSAM01 is not compatible with this control. The compatible modules are SYSTXBBRCT01 and SYSTXBBRWF01. The SAM is used for home automation purposes. The Evolution Connex control must have at least Version 8 or newer to be compatible with the SAM.
NOTE: For more information regarding the SAM Module, reference the latest version of the application specification entitled “Carrier Communicating HVAC System” (Version 2 or later), available on HVACpartners.com, or the System Access Module Installation Instructions.
5.6. Searching for Zones (If Applicable)
This function is not available with the 986T furnace.
“Zoning -- Searching” will appear on the screen to determine if any zones are present. The screen will show Zone 1, Zone 2, etc. and indicate all zones having either a Remote Room Sensor, or smart sensors associated with them. If the system contains smart sensors, they must be assigned a zone number before continuing. See the Smart Sensor Installation Instructions on how to assign Smart Sensors to their respective zones. After each zone has been identified, touch NEXT.
