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
the unit and in instructions or manuals, be alert to the potential for
personal injury. Understand the signal words DANGER,
WARNING, and CAUTION. 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.

The Evolution Zone System consists of several intelligent
communicating components which includes the Evolution Zone
2
Control (or User Interface), Smart Sensors, Damper Control
2
Module, variable speed furnace or FE fan coil, 2- -stage AC or HP
3
and Evolution Packaged Products, which continually communicate
with each other via a four- -wire connection called the ABCD bus.
5
Commands, operating conditions, and other data are passed
7
continually between components over the ABCD bus. The result is
8
a new level of comfort, versatility, and simplicity.
All Evolution furnaces or fan coils are variable- -speed and
8
multi- -stage for maximum flexibility, efficiency, and comfort. They
8
support controlled ventilation, humidification, dehumidification,
8
and air quality control. Either an Evolution (communicating) or a
standard 24VAC controlled outdoor unit may be used.
13
When using conventional outdoor units, the Evolution furnace or
14
fan coil provides the 24 volt signals needed to control them. Also,
15
the Evolution Damper Control Module (P/N SYSTXBB4ZC01)
allows connection of a Bryant HRV or ERV without the need for a
18
separate wall control.
19
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.

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. D S1 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. - Page 4 5. Drill two 3/16- -in. (4.8 mm) mounting holes in wall where marked. 6. Secure mounting plastic to wall using two screws and an- chors provided. D S1 7. Adjust length and routing of each wire to reach each wire entry on the connector backplate.
