INTRODUCTION
Bryant’s Evolutionr Smart Sensors are optional replacements for
Remote Room Sensors used with Evolution Zoning systems. It
provides a temperature display and buttons to adjust the desired
temperature within the zone. It also displays outdoor temperature
and indoor humidity. When used with an Evolution Connext
Control wall control-- FAN, HOLD and HOLD UNTIL features are
available. When used with an Evolution User Interface (UIZ) wall
control-- FAN, HOLD, OVERRIDE, UNOCCUPIED features are
available.
INSTALLATION CONSIDERATIONS
Any zone may use an Evolution Smart Sensor. The Evolution
Smart Sensor can be “home run” wired directly to the Damper
Control Module, or “daisy chained” from the wall control or
another Smart Sensor via 4--wire ABCD communication bus.
Ordinary thermostat wire is recommended; however, solid
conductor, stranded, or shielded wire may be used. Use 22 AWG or
larger for normal wiring applications. Continuous wire lengths
over 100 ft. should use 20 AWG or larger. Plan the connection of
each Smart Sensor to provide easiest wiring route.
NOTE: Whenever possible, it is suggested to always “home run”
wires back to the Damper Control Module for convenience of
troubleshooting. Using a “pig--tailed” connection, or a field
supplied terminal block may be helpful in achieving proper wire
termination at the Damper Control Module.
An Evolution Smart Sensor may now be used to control Zone 1. In
addition, a Remote Room Sensor may also be used in the same
zone. If a Remote Room Sensor is applied in the same zone, the
Remote Room Sensor has temperature priority over the Smart
Sensor.

WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing sensor, turn off all power to unit. There may
be morethan 1 power disconnect.
1. Turn OFF all power to unit.
2. If an existing thermostat or sensor is being replaced:
a. Remove existing device from wall.
b. Disconnect wiresfromexisting device, 1atatime.Becare-
ful not to allow wires to fall back into wall.
c. Discard or recycle old device.
d. If 4 wires exist in wall, they may be used. If not, plan and
route wiring to connect with either the Damper Control
Module, or User Interface. Multiple Evolution Smart
Sensors may be daisy chained together, but somewhere
chain must connect to either Damper Control Module or
the Evolution Connex Control/Evolution User Interface
wall control. (Smart Sensor daisy chain wire limit is 100
ft.)
Recommended connection is:
A -- Green = Data A
B -- Yellow = Data B
C -- White = 24vac (com)
D -- Red = 24vac (hot)
NOTE: It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consistently.
3. To mount Smart Sensor, remove rear mounting base. Route
wires through hole in mounting base and level base against
wall.
4. Mark wall through 2 mounting holes and drill two 3/16--in.
holes. Secure assembly to wall with 2 anchors and screws
provided, making sure all wires properly extend through
opening.
5. Adjust length and routing of thermostat wire to reach each
terminal entry on the connector. Strip 1/4--in. of insulation
from each wire and properly connect to A--B--C--D.

Failure to follow this caution may result in equipment damage
or improper operation.
Improper wiring or installation may damage the Smart Sensor.
Check to make sure wiring is correct before proceeding with
installation or turning on unit.
Step 3 — Setup and Checkout
NEW EVOLUTION SMART SENSOR SETUP
Upon initial power up, the Evolution Smart Sensor will need to be
properly addressed. “ZONE” will be displayed and default zone
number “2” will be shown in the temperature display. The word
“SETUP” will also appear in the lower left text area. Use the
TEMP (+/--) button to select the correct zone address number 1
through 8. If only one Damper Control Module exists, the zone
address selection will only be 1 through 4. Once the zone number
is selected, press the FAN button to store the zone address and exit
the setup menu. The Evolution Smart Sensor is ready to operate.
CHANGING ZONE ADDRESS
To change an existing zone address, enter the setup menu by
pressing the FAN button for 10 seconds until “ZONE” is
displayed. Use the TEMP (+/--) button to select the correct zone
address and then press the FAN button once to automatically save
and exit the setup menu. If no buttons are pressed for
approximately 3 minutes, the screen will automatically save and
exit back to a normal display.
To ensure that all changes are recognized by the main control,
perform the “Full Installation” function in the Installation &
Service Menu of the Evolution Connex Control. After zone
addresses are changed.
BACKLIGHTING
The LCD backlighting will energize whenever a button is pressed.
The backlighting will de--energize after 10 seconds of no push
button or activity. To enable constant backlighting, press the FAN

for approximately 3 minutes, the screen will automatically save and
exit back to a normal display.
FAN B UT TON
Pressing the FAN button momentarily will scroll through: AUTO,
LOW, MED, and HIGH speed continuous fan operation. The FAN
button is used to enter into the setup mode by holding the FAN
button for 10 seconds.
HUMIDITY/OAT BUTTON
Pressing the HUMIDITY/OAT button will toggle between the
Outside Temperature and Indoor Relative Humidity reading
(humidity reading at wall control). The LCD will revert back to the
outside temperature after 5 seconds.
COOL/HEAT BUTTON
Use the COOL/HEAT button to change between “COOL AT” and
“HEAT AT” setpoints.
TEMPERATURE UP/DOWN BUTTON
Use the TEMP (+/--) button to change a zone temperature setpoint.
Depending on the active heating/cooling mode, the “HEAT AT” or
the “COOL AT” setpoint will appear and will increment or
decrement accordingly. If not in a “HOLD” mode, changing the
setpoint, when used with an Evolution User Interface wall control,
will cause the Override timer to be displayed (i.e. 2--hours). If used
with an Evolution Connex Control wall control, changing the
setpoint will cause a HOLD UNTIL with a default time of
approximately 3 hours from the current time to be displayed. Either
the Override timer or default time can be increased or decreased by
using the TIME (+/--) button.
TIME UP/DOWN BUTTON
When used with Evolution User Interface wall control and the
TIME (+/--) button is pressed during a normal operation,
“OVERRIDE” is displayed and the Override timer is shown
(default is 2--hours). When used with an Evolution Connex
Control wall control and the TIME (+/--) button is pressed during a
normal operation, pressing the setpoint will cause a HOLD UNTIL
with a default time of approximately 3 hours from the current time
to be displayed. When used with either wall control, the Override
timer or default time can be increased or decreased by using the
TIME (+/--) button. While the timer or default time is shown, the
TIME buttons can be used to raise or lower the Override timer or
the default time in 15--minute increments up to a maximum of 24
hours. If the time is decreased to zero, the “OVERRIDE” text
disappears along with the timer or the default time will be replaced
with “SCHEDULED,” depending on the type of wall control, and
the program resumes regular operation.
NOTE: If the wall control is configured for non--programmable
operation, the Evolution Smart Sensor will ignore HOLD and
Override functions at the Smart Sensor.
HOLD BUTTON
Pressing the HOLD button momentarily will cause “HOLD” to be
displayed. The system will continue using the active (displayed)
temperature setpoints indefinitely. Pressing the HOLD button again
removes the “HOLD” text and the system resumes normal
programming schedules. When used with an Evolution User
Interface wall control, pressing the HOLD button for
approximately 3 seconds will cause “UNOCCUPIED” to be
displayed in the lower left area of the LCD and the unoccupied
temperature settings will be displayed. Pressing the HOLD button
again cancels the “UNOCCUPIED” mode and the system resumes
normal programming schedules.
NOTE: The Evolution Connex Control System does not include
an “unoccupied” mode.
