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.
INSTALLATION AND START--UP
OVERVIEW
This instruction covers installation of the Infinity Control
only
.
Physical installation instructions for the indoor and outdoor
equipment, and accessories are provided with each unit.
Setup, commissioning, operation, and troubleshooting of the
Infinity System are covered only in this installation instruction. It is
the guide to connecting
the system components and
commissioning the system once all physical components are
installed. Special screen prompts and start--up capabilities are
provided in the Infinity System to simplify and automate the initial
commissioning of the system.
S
Install Infinity Control according to this instruction.
S
Install indoor unit, outdoor unit, and accessories accord-
ing to their instructions.
S
Wire complete system according to this instruction.
S
Setup, commission, and operate system according to this
instruction to assure a smooth and trouble free start--up.
INSTALLATION
Check Equipment and Job Site
Inspect equipment. File claim with shipping company prior to
installation if shipment is damaged or incomplete.
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, fire-
place, 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.
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)
