Step 2 — Evolution 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 CONTROL™ LOCATION— The Evolution Con-
trol™ is the command center for the Evolution System. 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 Control™ 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 duct work.
The Evolution Control™ 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 SENSOR OPTION — A remote room sensor can be
used with the Evolution Control™ to take the place of the internal
temperature sensor. This allows the 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 is wired to the terminal
block connectors labeled S1 and S2. The Evolution Control™ will
automatically detect the remote sensor and ignore its internal
sensor. It is also important to note the humidity sensor cannot be
remotely located, so do not locate the Evolution Control™ in an
area where humidity sensing may not be accurate.
NOTE:
S1 & S2 connection on UI back-plate is now used for the
Remote Room Sensor, NOT for OAT Sensor hookup (S1 & S2
was previously used for OAT).
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
the installation.
Each device in the Evolution 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.
MOUNTING EVOLUTION CONTROL™ — There are two
options for mounting the Evolution Control™ to the wall. First,
familiarize yourself with all plastic assembly pieces shown in Figs.
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 Control™ location is ac-
ceptable 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 figure 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 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 Control by rocking up/down until interlocking 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 the back of the recessed mount backplate or
surface mount backplate before securing to the wall. See Fig. 8 and
9 for a larger decorative backplate (5.75
″
wide X 6
″
tall), which
can be ordered separately.
