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”,
“Zone”, “Fan”, “Left--Side” and “Right--Side” buttons, etc. These

Duct Assessment

The following screen will appear after STATIC PRESSURE screen

Assessment will measure the relative size of the ductwork, up to
and through the dampers. These measurements are used to control

the correct amount of airflow in the zoned system. Status messages
will appear on the screen to indicate what the system is doing. The
process will take approximately one minute per zone. The duct
assessment will override a call for heat or cool.

A duct assessment will automatically occur each day at a user
selectable time. The factory default time is 1:00 p.m. but, may be
changed by entering the Zoning Setup menu. See Zoning Setup
section of this manual. The duct assessment will override a call for
heat or cool. The system will first open all zones and drive the
blower to 175 CFM/ton o f cooling (or the minimum indoor unit’s
airflow, whichever is greater). It will then take a static pressure
measurement. The system will then close all zones and open one
zone at a time, taking a static pressure measurement for each zone.
The system will then close all zones and take a pressure
measurement, getting a value for the duct leakage up to and
through the dampers. With these static pressure measurements, the
system will calculate the relative size of each zone as well as the
percent leakage through the dampers At the end of the process, the
display will show the relative size of each zone duct. See Fig. 20.

If the User Interface detects an error (damper not moving or
damper wired backwards), it will perform the duct assessment
again. If it still detects a damper problem, it will default the
measurements into equal sizes, with 10% leakage, and display the
zone number for the suspected zone damper.

the system.

NOTE: A Duct Assessment will automatically occur every 24
hours at selected time to check system static and calibrate dampers.

Sensor / Damper Check:

The Sensor/Damper Check allows the installer to check each zone
damper for operation, as well as insure the zone sensor corresponds
to that particular zone.

When first initiated, the Zone 1 damper will fully open, and all
other zones will close. Using the scroll button, the installer can
select each zone and verify the damper is fully open while all other
dampers remain closed.

After proper damper operation has been verified, the installer can
now check and verify that each Remote Room Sensor corresponds
to the proper zone damper in the same zone. Start from the top and
highlight zone 1 to open damper. Temporarily disconnect any other
zone Remote Room Sensor (at sensor location). That zone damper
will now open, while the Zone 1 damper will close.

EXAMPLE: If the Zone 2 Remote Room Sensor is disconnected,
the Zone 2 damper will now open as indicated on the User
Interface display. The word “FAIL” will also be displayed instead
of the actual temperature for Zone 2. Reconnect Zone 2 sensor and
try all remaining sensors one at a time in the system. Smart Sensors
may also be checked, see Smart Sensor Installation Instructions for
procedure.

Airflow Limits:

S LOW

S MED LOW

S MED

S MED HIGH

S HIGH (default)

S NO LIMIT

Because there is no bypass damper, the Zone Airflow Limit check
will allow the installer to assess the airflow noise generated by the
system providing the maximum amount of airflow to each zone.
Select ZONE, then select AIRFLOW LIMIT: When Start is
pressed (right side button), the selected zone’s damper will fully
open, all others will close, and the indoor unit will provide the
maximum airflow for that zone (as selected in SETUP —
ZONING, Airflow Limits). If the airflow noise is objectionable, the
installer can select a lower airflow noise limit. If the noise is not
objectionable, the installer should leave HIGH selected, or even
NO LIMIT.

NOTE: Selecting a lower airflow noise limit may decrease the
homeowner’s comfort in that zone.

Continuous Fan Operation

Pressing FAN button will scroll through the following:

S AUTO = No fan operation except during equipment operation.

S LOW = Approximately 50% of High Speed operation.

S MED = Half way between High and Low speed operation.

S HIGH = Highest of either High Heating or High Cooling CFM.

Continuous fan operation is programmable. The programming
option must be enabled in the Thermostat Setup. See the
Homeowner’s Manual for detailed instructions on programming
the fan.

Five--Minute Compressor Timeguard

This timer prevents compressor from starting unless it has been off
for at least 5 minutes. It can be defeated by simultaneously pressing
the Fan and Temp + buttons.

Emergency Heat (for heat pump applications)

To activate Emergency Heat, you must press and hold the HEAT
button for 3 seconds to activate. Repeat to deactivate.

Heat Source Selection (Hybrid or Hydronic Heat)

UIZ01--D

If user wishes to override normal operation in Hybrid Heat or
Hydronic Heat applications, press and hold the heat button for 3
seconds to select desired heat source.

Keypad Lockout

Keypad can be locked by pressing “Fan” and “ZONE” buttons at
the same time for 3 seconds. When keys are locked, a lock symbol
will appear in the upper left corner of screen. Follow same
procedure to unlock keypad.

Heat and Cool LED

The Heat and Cool LEDs will pulsate during actual equipment
operation. This can be defeated in the Advanced Setup Screens.

Equipment Cycle Timer (adjustable 4--6 cycles per
hour)

This timer prevents the start of a heating or cooling cycle until 15
(or 10) minutes after the last start of the same cycle. Its function is
to assure that the equipment is not cycled more than the selected
times per hour. This timer is adjustable from 4 to 6 cycles per hour.
This timer is defeated for one cycle when the desired temperature is
manually changed. It can also be defeated for one cycle by
simultaneously pressing the Fan and Right Up buttons.

Staging Timer

In multistage heating or cooling, this timer prevents any higher
stage from turning on until the preceding stage has been on for 10
minutes.

In Hybrid Heat, the staging timer is 15 minutes between heat pump
and gas furnace operation. A demand of 5_F(3_C) or more will
override the staging timer and allow higher stages to energize.

Three--Minute Minimum On Time

In normal operation, when a stage turns on, it will remain on for a
minimum of three minutes. If the setpoint is changed, this timer is
automatically cancelled, allowing the equipment to turn off
immediately when the demand is removed.

Heat/Cool Setpoints (Desired Temperatures)

A minimum difference of 2_F(1_C) (default) is enforced between
heating and cooling desired temperatures. This is done by allowing
one setting to “push” the other to maintain this difference. This
difference is adjustable via the Install/Service menu under
Thermostat Setup.

Temperature Display

The actual temperature displayed is always rounded toward the
setpoint. This is because the system is operating and measuring the
temperature in sixteenths of a degree, but displaying in whole
numbers. The system may be turned off and on within .5_ of

setpoint, but the display may not change. This is by design and
does not indicate a problem with the control.

Auto Changeover

When Auto mode is enabled (factory default) a change from heat
to cool (or vice versa) will not occur until an opposite mode
demand has existed for 30 minutes. If the setpoint is changed, the
30-- minute requirement is defeated. This Auto Changeover time is
adjustable via the Install/Service menu under Thermostat Setup.
Range = 5 -- 120 min.

Smart Recovery

With Smart Recovery selected (factory default), transition out of
setback begins 1.5 hours before selected recovery time and
gradually adjusts room temperature so desired temperature will be
achieved at selected recovery time. It operates in both heating and
cooling. This only applies to programmable operation.

For example: Set back temperature in heating is 64_F. S mart
Recovery setpoint is 70_F at 7:00 a.m. At 5:30 a.m., the control
calculates the required temperature recovery rate (recovery temp -­set back temp or current temp if greater) / 90 minutes. If the current
temp at 5:30 = 66_F, the recovery rate = (70 -- 66)_F/90 minutes =

0.04_ per minute. In order to achieve setpoint, the control ramps up
the setpoint 0.04 _F / minute from 5:30 a.m. until 7:00 a.m. This
changing setpoint is displayed while it is occurring.

NOTE: Temperatures should not be set back so far that the
equipment cannot recover in 90 minutes.

Air Filter

If AIR FILTER or AIR PURIFIER is installed in the indoor unit,
the system will perform a static pressure check of the system every
24 hours at 1:00 p.m. to monitor filter accumulation (TrueSenset
Dirty Filter Detection) or whenever power is applied to the system
or the system is transitioned from Off to Cool or Heat modes. The
blower will run at a medium airflow for one minute.

This system operates by setting a base line static pressure based on
the highest airflow the system could run (this could be heat or cool
airflow). The measurement is taken at a low airflow and then
calculated up to the highest airflow the system could see.

Unoccupied

Pressing the HOLD button for 3 seconds will set the selected zone
to unoccupied status. A zone may also be programmed to be
unoccupied in any period of the schedule. An unoccupied zone is
used as a dump zone to alleviate high static or noise situations.
Utilizing this feature will help keep occupied zones at acceptable
temperatures and noise levels. The temperature in an unoccupied
zone is controlled to a maximum and minimum settings that are
selectable in the Advanced Setup. If the entire system is set to
Unoccupied, the humidity is controlled within the range selected in
the Unoccupied Advanced Setup. An unoccupied zone will be
allowed to be conditioned up to the most conditioned zone
setpoint, if necessary.

All Zones

Pressing the ZONE button for 3 seconds will gray out the entire
display and put the User Interface into “ALL ZONES” mode
(indicated by “All Zones” in upper left of the display). Any
changes to set temperature, fan, or Hold status will occur in all
zones when the screen is exited. Press the ZONE button to exit
“All Zones” mode. If no buttons are pressed for one minute, the
control will exit All Zones.

Frozen Coil Detection

During cooling operation, the User Interface will monitor the static
pressure of the system. If the static pressure is increasing
dramatically, the User Interface will turn off cooling for up to one
hour, record fault in the “Last 10 Events” screen, and run the fan at
a reduced airflow. The User Interface will continue to monitor the
static pressure. If it is reduced before one hour has elapsed, it will
resume cooling operation. After one hour, cooling will be resumed.

Airflow Limits and Equipment Protection

The maximum airflow allowed into a zone is based on the relative
size of the zone determined by the duct assessment and the airflow
limits selected for each zone. Airflow limits are set at High as
factory default. This means that 250% of assessed airflow is
allowed into the zone.

If the system determines that it cannot deliver the airflow into a
zone that needs conditioning, and that zone has an airflow limit
selected, the system will take the following 4 steps:

Step 1 — Reduce airflow if possible

a. 275 CFM per ton minimum in cooling. 175 CFM/ton

for low stage cooling if 2--stage unit is installed.

b. Comfort Heat airflow is minimum for heat pump heat-

ing (3.5 X Outdoor Temp + 137) CFM/ton.

c. No adjustment for furnace heating

Step 2 — Dump air to unoccupied zones

a. Unoccupied zones can be conditioned up to the most

conditioned setpoint.

Step 3 — Dump air to zones with less conditioned
setpoints

a. Zones with lower setpoints in heating and higher set-

points in cooling may be conditioned to within 3_F
(1.7_C) of the most conditioned setpoint.

b. Increase or decrease unoccupied zones 0.75_F(.4_C).

Step 4 — Single stage cooling

a. System will reduce airflow to 275 CFM/ton in single

stage cooling systems.

Step 5 — Stage down equipment

a. Equipment stage down or shut off if necessary.

b. Fault history will record an event of “AIRFLOW LIM-

ITED STAGEDOWN OCCURRED” on stagedown and
“EXCESS STATIC PRESSURE” if shut down.

c. If shut down occurs, other zones need to call before

equipment will resume operation.

Dehumidify Operation

Once a target cooling humidity setpoint is selected in the Advanced
Setup COOLING HUMIDITY screen, two other setup options
affect Dehumidify operation: COOLING AIRFLOW and
DEHUMIDIFY.

COOLING AIRFLOW: Setting this to COMFORT or QUIET
will enable the system to use low airflow to help dehumidify the
space. If duct sweating becomes an issue, setting DEHUM
AIRFLOW to HIGH may resolve the problem.

DEHUMIDIFY: Located in the Cooling Humidity screen of the
Advanced Setup, this option has 2 settings: ON and OFF.

If DEHUMIDIFY is set to ON (factory default), then the cooling
unit will be allowed to overcool the space up to 3_F(.6_C) if the
humidity level is above the cooling humidity target setpoint.

The amount of over--cooling allowed varies with the
dehumidification demand, the cooling demand, and the actual
space temperature. More over--cooling is allowed with greater
dehumidification demand.

When the space temperature is at or above 75_F(24_C) and the
dehumidify demand is high, over--cooling up to 3_F(1.7_C) is
allowed. As the space temperature approaches 70_F(21_C), less
over--cooling is allowed. At 70_F(21_C) space temperature, no
more over--cooling is allowed no matter how great the dehumidify
demand. This is done to protect the equipment.

Hybrid Heat Setup / Operation

Furnace Lockout Operation — (in HYBRID HEAT SETUP

menu) is the outside temperature above which the furnace will not
run except for defrost (otherwise known as the aux heat lockout).

Heat Pump Lockout Operation — (in HYBRID HEAT SETUP)
is the outside temperature below which the heat pump will not run
(otherwise known as the balance point).

These values can be set identical to each other. If they are not
identical, the system will stage up and down normally from heat
pump to furnace when the outside temperature is between these
settings. The User Interface will not allow the heat pump lockout
setting to be above the furnace lockout setting.

The factory default settings for both of these is NONE (no
lockouts). Even though a furnace lockout temperature may be set,
the system will still use the furnace in defrost operation, and may
stage back down to heat pump when defrost is completed after a 2
minute delay.

Hybrid Heat Defrost — (in HYBRID HEAT SETUP) When the
outdoor unit needs a defrost cycle, the furnace will run during
defrost regardless of lockout temperature, unless told not to in the
Hybrid Heat Setup screen. After defrost, the system may stage
down to heat pump after a 2 minute delay.

If the room temperature falls below 40_F(4_C) and a furnace
lockout is in enabled, the furnace lockout will be overridden to
bring on the furnace.
