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
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.

INSTALLATION
Step 1 — Select Smart Sensor Location
Sensor should be mounted:
S Approximately 5 ft. (1.5m) from floor. S Close to center of zone, preferably on inside partitioning wall. S On section of wall without pipes or ductwork. S Where wiring can be routed to it within wall. Avoid running
directly next to other AC power.
Sensor should NOT be mounted:
S Close to a window, on outside wall, or next to a door leading to
the outside.
S Exposed to direct light and heat from a lamp, sun, fireplace, or
other temperature radiating object which may cause a false reading.
S Close to or in direct airflow from supply registers and return--air
grilles.
S In areas with poor air circulation, such as behind a door or in an
alcove.
S Do not run wires next to AC power lines.

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.

CAUTION
ELECTRICAL OPERATION HAZARD
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
