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 EvolutionrSystem consists of several intelligent communicating components
which include the EvolutionrConnex Control (or User Interface), variable speed
furnace or FE fan coil, 2--stage AC and HP, (including Geothermal units),
multi--stage AC and HP, variable capacity HP and AC units, and Evolution Connex
System Package units 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 Evolution System 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 Evolution
System (communicating), or a standard single--stage 24VAC controlled outdoor unit
may be used.
When using conventional single--stage outdoor units, the Evolution System furnace
or fan coil provides the 24 volt signals needed to control them. When using
multi--stage conventional outdoor units or heat pumps, an Evolution System
Network Interface Module or ”NIM” (P/N SYSTXBBNIM01) may be required to
provide additional control outputs. Also, the NIM allows connection of a Bryant
HRV or ERV without the need for separate wall control.
When using a Bryant HRV or ERV with a zoned system, the Evolution System Zone
board allows connection of a Bryant HRV or ERV without the need for separate
wall control or NIM.
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 Evolution Connex Control and the
Evolution 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 Evolution System are
covered in this installation instruction at a high level. More detailed information
may be available in the Evolution System HVAC equipment Installation
Instructions. 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.
SInstall the Evolution Connex Control according to this instruction.
SInstall indoor unit, outdoor unit, and accessories according to their instructions.
SWire complete system according to this instruction.
SSetup, commission, and operate system according to this instruction, and as
supplemented in the HVAC equipment Installation Instructions, to assure a
smooth and trouble free start--up.
SNote that some detailed equipment configuration and service information may
be included with the equipment instructions. Please refer to the equipment
installation instruction manuals, and applicable technical training materials, for
all devices for complete information.
4.2. Check Equipment
Inspect equipment. File a claim with shipping company prior to installation if
shipment is damaged or incomplete.

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, state, and local 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, Remote Room Sensors and Smart Sensors
SHOULD be mounted:
SApproximately 5--ft (1.5 m) from the floor.
SClose to or in a frequently used room, preferably on an inside partitioning wall.
SOn a section of wall without pipes or ductwork.
The Evolution Connex Control and Sensors SHOULD NOT be mounted:
SClose to a window, on an outside wall, or next to a door leading to the outside.
SExposed to direct light or heat from a lamp, sun, fireplace, or other
temperature--radiating objects which could cause a false reading.
SClose to or in direct airflow from supply registers.
SIn areas with poor air circulation, such as behind a door or in an alcove.

8
4.3.2. Wired 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.
NOTE: Humidity sensing will occur ONLY at the Evolution Connex Control. The
wired Remote Room Sensor does NOT have humidity sensing capability.
4.3.2.1. Wired 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 Zone Sensor (SYSTXBBSMS01). 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 Zone 1
Evolution Connex 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,
one wired Remote Room Sensor may also be used in the same zone. The wired
Remote Room Sensor has priority over the Smart Sensor; the Smart Sensor will
display the wired Remote Room Sensor temperature, when used.
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. See Section 4.4.1 for notes on shielded
wire. Continuous wire lengths over 25 ft. should use 18 AWG wiring.

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 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)
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, typically those with multiple compressor stages,
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 one disconnect switch. Lock out and tag
switch with a suitable warning label.
!WARNING
4.4.1. Shielded Wire and Communication Bus Configura-
tion
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 Evolution Connex Control. 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.
