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--stage AC or HP
and Evolution Packaged Products, 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 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 (communicating) or a
standard 24VAC controlled outdoor unit may be used.
When using conventional outdoor units, the Evolution 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 Bryant 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.
Design Considerations
The Evolution Zone system is unique because a bypass damper
must not be used. This is possible due to the intelligence of the
system and variable speed motor technology. For trouble--free
applications, the following parameters should always be met:
1. Zones should be sized so that each zone can deliver at least
the minimum airflow for the system in both heating and
cooling modes.
2. Oversize duct work by 25% to avoid excess noise at minimum zone airflow.
3. Be aware that heating airflow may be higher than cooling
airflow depending on equipment combination.
INSTALLATION, 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 are covered in this installation instruction.
It is the guide to connecting the system components and
UIZ01--D
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 Evolution Zone 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.
INSTALLATION
Check Equipment and Job Site
Inspect equipment. File claim with shipping company prior to
installation if shipment is damaged or incomplete.
Evolution Zone Control Location and Wiring
Considerations
The Evolution Zone Control and 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.
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.
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 ZS1 and ZS1C 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.
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.
Remote Sensor Averaging
Typically, one Remote Room Sensor is used per zone, 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 Fig. 2 in this manual for wiring diagram.

WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect power before routing control wiring.
All wiring must comply with national, local, and state codes.
Evolution Zone Control Location
The Evolution 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:
S Approximately 5--ft (1.5 meters) 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.

Fig. 2 -- Remote Room Sensor -- Parallel Wiring
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
sensed at the User Interface. 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.

Wiring Considerations
Ordinary thermostat wire is recommended. Use 22 AWG or larger
for normal wiring applications. Continuous wire lengths over
100-- ft. (3 m) 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.
Shielded Wire
If the thermostat wiring will be located near or in parallel with high
voltage wiring, cable TV, Ethernet wiring, or radio frequency
equipment, then shielded thermostat wire 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.
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.

A03193
Fig. 11 -- Wire ABCD Connector
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 24VAC isolation 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.
!
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.
dampers, humidifier, ventilator, UV lights, etc.).
12. Turn on power to equipment.
See wiring diagrams Fig. 8, 9, and 10 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. 8, which includes an indoor
communicating furnace or FE fan coil, with a 2-- stage Puronr
refrigerant communicating outdoor unit. No additional OAT
(outdoor air temperature) sensor is required because the Evolution
Zone Control will use the temperature sensor inside the outdoor
unit.
In a hybrid heat installation with a non--communicating heat pump,
an OAT sensor must be installed or the heat pump will not run.
See wiring diagram, Fig. 9, for connecting an indoor
communicating furnace or FE fan coil with a 1--stage 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. 10 for connecting an FE fan coil with a
1-- stage 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.
!
CAUTION
EQUIPMENT HAZARD
Failure to follow this caution may result in equipment damage.
Do not apply 24VAC fan powered humidifier (with internal
power supply) direct to indoor unit HUM and COM terminals.
INITIAL POWER--UP
NOTE: Refer to Functional Overview (Fig. 12) to become
familiar with key function buttons such as “System On/Off”,
