SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow all
local electrical codes during installation. All wiring must conform
to local and national electrical codes. Improper wiring or
installation may damage the Infinity System.
Recognize safety information. This is the safety-- alert symbol
.
When you see this symbol on the equipment and in the instruction
manual, be alert to the potential for personal injury. Understand the
signal words DANGER, WARNING, and CAUTION.
These words are used with the safety --alert symbol. DANGER
identifies the most serious hazards, which will result in severe
personal injury or death. WARNING signifies a hazard, which
could result in personal injury or death. CAUTION is used to
identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
INTRODUCTION
The Infinity System consists of several intelligent communicating
components which includes the Infinity Control (or User
Interface), variable speed furnace or FE fan coil, 2--stage AC or HP
and Infinity Packaged Products, which continually communicate
with each other via a four--wire connection called the ABCD bus.
Commands, operating conditions, and other data are passed
continually between components over the ABCD bus. The result is
a new level of comfort, versatility, and simplicity.
All Infinity furnaces or fan coils are variable--speed and multi stage
for maximum flexibility, efficiency, and comfort. They support
controlled ventilation, humidification, dehumidification, and air
quality control. Either an Infinity (communicating), or a standard
24VAC controlled outdoor unit may be used.
When using conventional outdoor units, the Infinity furnace or fan
coil provides the 24 volt signals needed to control them. Also, the
Infinity Network Interface Module (P/N SYSTXCCNIM01) allows
connection of a Carrier HRV or ERV without the need for a
separate wall control.
All system components are controlled through the wall mounted
Infinity Control, which replaces the conventional thermostat and
provides the homeowner with a single wall control for all features
of the system.

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:
S Approximately 5 feet (1.5 meters) from the floor.
S Close to or in a frequently used room, preferably on an inside
partitioning wall.
S On a section of wall without pipes or ductwork.
The Infinity Control and Room Sensors should NOT be mounted:
S Close to a window, on an outside wall, or next to a door leading
to the outside.
S Exposed to direct light or heat from a lamp, sun, fireplace, or
other temperature--radiating objects which could cause a false
reading.
S Close to or in direct airflow from supply registers.
S 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.

INSTALLING INFINITY CONTROL
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury,
death or equipment damage.
Before installing, modifying, or servicing system, the main
electrical disconnect switch must be in the OFF position.
There may be more than 1 disconnect switch. Lock out and
tag switch with a suitable warning label.
!
WARNING
1. Turn off all power to equipment.
2. If an existing User Interface or control is being replaced:
a. Remove existing control from wall.
b. Disconnect wires from existing control.
c. Discard or recycle old control.
NOTE: Mercury is a hazardous waste, if existing control contains
any mercury, it MUST be disposed of properly. The User Interface
does not contain mercury.
3. Select Infinity Control mounting plastic (recess mount or
surface mount and decorative backplate if desired).
4. Route wires through large hole in mounting plastic. Level
rear plastic against wall (for aesthetic value only -- Infinity
Control need not be level to operate properly) and mark
wall through two mounting holes.
5. Drill two 3/16” (4.8 mm) mounting holes in wall where
marked.
6. Secure mounting plastic to wall using two screws and an-
chors provided.
7. Adjust length and routing of each wire to reach each wire
entry on the connector backplate. Strip 1/4” (6.4 mm) of in-
sulation from each wire.
8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram Fig. 11, 12,
and 13.

Fig. 14 -- Wire ABCD Connector
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Improper wiring of the ABCD connector will cause the
Infinity System to operate improperly. Check to make sure all
wiring is correct before proceeding with installation or turning
on power.
CAUTION
!
9. Push any excess wire into the wall. Seal hole in wall to pre-
vent any air leaks. Leaks can affect operation.
10. Attach Infinity Control to the mounting plastic by lining up
the plastic guides on the back of the control with the open-
ing on the mounting plastic and push on.
11. Perform installation of all other system equipment (i.e.
dampers, humidifier, ventilator, UV lights, etc.)
12. Turn on power to equipment.
See wiring diagram, Fig. 11, which includes an indoor
communicating furnace or FE fan coil, with a communicating
outdoor unit. No additional OAT (outdoor air temperature) sensor
is required because the Infinity Control will use the temperature
sensor inside the outdoor unit.
See wiring diagram, Fig. 12, for connecting an indoor
communicating furnace or FE fan coil with a 1 --stage air
conditioning unit (non-- communicating outdoor). An Outdoor Air
Temperature (OAT) sensor may be installed (but is not required) at
the indoor furnace or fan coil OAT terminals. When OAT sensor is
applied, the Infinity System will provide enhanced system features
and benefits.
See wiring diagram, Fig. 13, for connecting an FE fan coil with a
1-- stage heat pump (non--communicating outdoor unit). When
OAT is applied, the Infinity System will provide enhanced system
features and benefits.
NOTE: For other applications not listed, refer to the Network
Interface Module (NIM) Installation Instructions.
Humidifier Connection
A 24VAC bypass or fan powered humidifier may be installed.
NOTE: Do Not Use a traditional humidistat to control humidifier
operation. If a humidifier is installed, let the Infinity Control
operate humidifier.
Bypass Humidifiers
A bypass humidifier should be wired directly to the furnace or fan
coil HUM and 24VAC COM terminals. The Infinity Control will
automatically energize the HUM output during a call for
humidification.
Fan Powered Humidifiers
Most fan powered humidifiers produce internal 24VAC in order to
energize upon a switch or contact closure. For this application, a
24VAC N.O. Isolation Relay (DPST) MUST be used to prevent
mixing the internal humidifier power with the indoor equipment
transformer. Applying 24VAC isolation relay coil to furnace or fan
coil HUM and COM terminals will allow the Infinity Control to
automatically energize the HUM output during a call for
humidification. The N.O. relay contacts will be used to energize the
humidifier. See fan powered humidifier installation instructions for
more details.
EQUIPMENT HAZARD
Failure to follow this caution may result in equipment damage.
Do not apply 24VAC fan powered humidifier (with internal
power supply) direct to indoor unit HUM and COM terminals.
