Infinity Control Location and Wiring

Considerations

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury

or death.
Disconnect power before routing control wiring.

WARNING

All wiring must comply with national, local, and state codes.
Infinity Control Location
The Infinity Control User Interface is the command center for the

Infinity 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 Infinity 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 Infinity 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 Infinity Control to

take the place of the User Interface internal temperature sensor.

This allows the Infinity 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 Infinity Control will automatically detect the

Remote Room Sensor and ignore its internal temperature sensor.

Typically, one remote sensor is used 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. It is also important to note the humidity sensor

cannot be remotely located, so do not locate the Infinity Control in

an area where humidity sensing may not be accurate.
NOTE: S1 & S2 connection on User Interface backplate is now
used for Remote Room Sensor, NOT for OAT Sensor hookup.
Wiring Considerations
Ordinary thermostat wire is recommended. Use 22 AWG or larger
for normal wiring applications. Continuous wire lengths over 100

ft. should use 20 AWG or larger.

Fig. 2 -- Remote Room Sensor -- Parallel Wiring

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 Infinity 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 Infinity Control

There are two options for mounting the Infinity Control to the

wall. First, become familiar with all plastic assembly pieces shown
in Fig. 3 through 10. The User Interface will snap together with

either the Recess Mount or the Surface Mount backplate.
Recess Mount
This provides the thinnest mounting configuration (see Fig. 4). The
backplate containing the recessed terminal block can be mounted

directly to the wall by cutting a hole 1 1/2” (38.1 mm) wide by 2

1/8” (54 mm) high. Mark location and cut hole in wall.
NOTE: Always ensure the Infinity Control location is acceptable
before cutting any holes in wall.
Surface Mount
This provides surface mounting configuration, which allows use of

a small hole in the wall. A surface mount backplate is supplied (see
Fig. 5). Attach backplate as shown in Fig. 8, 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 Infinity 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
Infinity Control by rocking up/down until interlocking tabs release.
Decorative Backplate
Supplied is a thin decorative backplate (see Fig. 6) 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. 9 and 10 for a larger decorative backplate
P/N SYSTXXOLBP01 (5.75”/146 mm wide x 6”/152 mm high),

which can be ordered separately.
