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
product. 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 includes the EvolutionrConnextControl (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.

2
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 Evolutionrfurnaces 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 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.

4.1. Overview
This instruction covers installation of the EvolutionrConnextControl and the
EvolutionrWireless 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 EvolutionrSystem 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.
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 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.

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:
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 Remote Room 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.

6
SClose to or in direct airflow from supply registers.
SIn 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.
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 EvolutionrZone 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)

8
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.
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
STurn off all power to equipment.
SIf an existing EvolutionrControl or other control is being replaced:
dRemove existing control from wall.
dDisconnect wires from existing control.

9
dDiscard or recycle old control.
SNOTE: 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.
SSelect Evolution Control mounting plastic (backplate and decorative backplate
if desired).
SRoute 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.
SDrill two 3/16--in (4.8 mm) mounting holes in wall where marked.
SSecure mounting plastic to wall using two screws and anchors provided.
SAdjust 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.
SMatch and connect thermostat wires to proper terminals on control backplate.
dSee wiring diagrams in Appendix A.
SPush any excess wire into the wall. Seal hole in wall to prevent any air leaks.
Leaks can affect operation.
SAttach 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.
SPerform installation of all other system equipment (i.e. dampers, humidifier,
ventilator, UV lights, etc.).
STurn 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

10
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.
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.

11
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.
A12214

12
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.
