B.Step 2 — Evolution Zone Control™ Location and Wiring Considerations
WARNING: ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or possible equipment damage.
Disconnect Power before routing control wiring.
All wiring must comply with national, local, and state codes. EVOLUTION™ ZONE CONTROL LOCATION— The Evolu- tion 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:
•Approximately 5 feet (1.5 meters) from the floor.
•Close to or in a frequently used room, preferably on an inside partitioning wall.
•On a section of wall without pipes or ductwork.
The Evolution™ Zone Control and Room Sensors should NOT be mounted:
•Close to a window, on an outside wall, or next to a door leading to the outside.
•Exposed to direct light or heat from a lamp, sun, fireplace, or other temperature-radiating objects which could cause a false reading.
•Close to or in direct airflow from supply registers.
•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 OS1 and OS1C 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.
NOTE: S1 & S2 connection on UI backplate is now used for Remote Room Sensor, NOT for OAT Sensor hookup.
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.
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. 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.
WIRING CONSIDERATIONS — Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal wiring applica- tions. Continuous wire lengths over 100 ft. 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.
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°C to 70°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 consid- eration.
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.
MOUNTING EVOLUTION™ ZONE CONTROL — There are two options for mounting the Evolution Zone Control™ to the wall. First, become familiar with all plastic assembly pieces shown in Fig. 2 through 9. The User Interface will snap together with either the Recess Mount or the Surface Mount backplate.
RECESS MOUNT — This provides the thinnest mounting con- figuration (See Fig. 3). The backplate containing the recessed terminal block can be mounted directly to the wall by cutting a hole 1 ½″ wide by 2 1/8″ high. Mark location and cut hole in wall.
NOTE: Always ensure the Evolution Zone Control™ location is acceptable before cutting any holes in wall.
SURFACE MOUNT — This provides surface mounting configu- ration, which allows use of a small hole in the wall. A surface mount backplate is supplied (See Fig. 4). Attach backplate as shown in Fig. 7, and the assembly will mount directly to the wall requiring only a small hole in the wall allowing a four wire connection to pass through.
NOTE: Once Evolution Zone Control™ is secured to wall with the backplate assembly (snapped together), care must be taken not to bend or break the interlocking tabs when removing. Gently remove Evolution Zone Control by rocking up/down until inter- locking tabs release.
DECORATIVE BACKPLATE — Supplied is a thin decorative backplate (see Fig. 5), to hide any marks/screw holes left from the previous thermostat. This decorative backplate (or beauty ring) can be used in either the recess or surface mount installation by snapping it onto back of recessed mount backplate or surface mount backplate before securing to wall. See Fig. 8 and 9 for a larger decorative backplate P/N SYSTXXOLBP01 (5.75″ wide X 6″ tall), which can be ordered separately.
