INTRODUCTION
The Infinity Zone System consists of several intelligent
communicating components which includes the Infinity Zone
Control (or User Interface), Smart Sensors, Damper Control
Module, 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 Damper Control Module (P/N SYSTXCC4ZC01) 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 Zone Control, which replaces the conventional thermostat
and provides the homeowner with a single wall control for all
features of the system.
Design Considerations
The Infinity Zone system is unique because a bypass damper must
not be used. This is possible due to the intelligence of the system
and variable speed motor technology. For trouble--free
applications, the following parameters should always be met:
1. Zones should be sized so that each zone can deliver at least
the minimum airflow for the system in both heating and
cooling modes.
2. Oversize duct work by 25% to avoid excess noise at minimum zone airflow.
3. Be aware that heating airflow may be higher than cooling
airflow depending on equipment combination.
INSTALLATION, ST ART--UP OVERVIEW
This instruction covers installation of the Infinity Zone Control
only. Physical installation instructions for the indoor and outdoor
equipment, Damper Control Module, and accessories are provided
with each unit.
Setup, commissioning, operation, and troubleshooting of the
Infinity Zone System are covered in this installation instruction. It
is the guide to connecting the system components and
UIZ01--V
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 Zone Control according to this instruction.
S Install indoor unit, outdoor unit, and accessories according 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 Zone Control Location and Wiring
Considerations
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 Zone
Control to take the place of the User Interface internal temperature
sensor. This allows the Infinity 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 ZS1 and ZS1C connection at the Damper Control
Module. In either case, the Infinity 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 Infinity Zone Control in an
area where humidity sensing may not be accurate.
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.
Remote Sensor Averaging
Typically, one Remote Room Sensor is used per zone, 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 in this manual for wiring diagram.

WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect power before routing control wiring.
All wiring must comply with national, local, and state codes.
Infinity Zone Control Location
The Infinity Zone Control User Interface is the command center for
the Infinity 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 Infinity Zone Control and Room Sensors should be mounted:
S Approximately 5--ft (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 Zone Control and Room Sensors should NOT be
mounted:
Sensor 3 Sensor 4

Fig. 2 -- Remote Room Sensor -- Parallel Wiring
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
sensed at the User Interface. Only one Smart Sensor may be used
per zone. They cannot be averaged like Remote Room Sensors. 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. The Smart Sensor will display the Remote
Room Sensor temperature.
NOTE: Smart Sensors must be addressed to identify which zone it
will control. See Smart Sensor Installation Instructions for details.
Wiring Considerations
Ordinary thermostat wire is recommended. Use 22 AWG or larger
for normal wiring applications. Continuous wire lengths over
100--ft. (3 m) 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
2
than four wires in the event of a damaged or broken wire during
installation.
Each communicating device in the Infinity 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.
If the thermostat wiring will be located near or in parallel with high
voltage wiring, cable TV, or Ethernet wiring, then shielded
thermostat wire can be used to reduce or eliminate potential
interference. The shield wire should be connected to the C
terminal, or ground, at the indoor unit. The shield wire should
NOT be connected to any terminal at the user interface.
Connecting the shield to ground at both ends can cause current
loops in the shield, reducing shield effectiveness.
Shielded Wire
If the thermostat wiring will be located near or in parallel with high
voltage wiring, cable TV, Ethernet wiring, or radio frequency
equipment, then shielded thermostat wire can be used to reduce or
eliminate potential interference. The shield wire should be
connected to the C terminal, or ground, at the indoor unit. The
shield wire should NOT be connected to any terminal at the user
interface. Connecting the shield to ground at both ends can cause
current loops in the shield, reducing shield effectiveness.
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_Cto70_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
consideration.
!
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.
CAUTION
Mounting Infinity Zone Control
There are two options for mounting the Infinity Zone 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 Zone 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 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
Infinity Zone 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” / 1 52 mm
high), which can be ordered separately.
!
WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing Infinity Zone Control, turn off all power to
equipment. There may be more than one power source to
disconnect.
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 Zone 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
Zone Control need not be level to operate properly) and
mark wall through two mounting holes.
5. Drill two 3/16--in. (4.8 mm) mounting holes in wall where
marked.
6. Secure mounting plastic to wall using two screws and anchors provided.
7. Adjust length and routing of each wire to reach each wire
entry on the connector backplate. Strip 1/4--in. (6.4 mm) of
insulation from each wire.
8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram Fig. 11, 12,
and 13.

CAUTION
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 Zone System to operate improperly. Check to make
sure all wiring is correct before proceeding with installation or
turning on power.
9. Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation.
10. Attach Infinity Zone Control to the mounting plastic by lining up the plastic guides on the back of the control with the
opening 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 diagrams Fig. 11, 12, and 13 for connecting the Infinity
Zone Control and Smart Sensors to the Damper Control Module.
More information regarding Damper Control set-- up and wiring
can be found in Damper Control Module Installation Instructions.
See wiring diagram, Fig. 11, which includes an indoor
communicating furnace or FE fan coil, with a 2 --stage Puron
refrigerant communicating outdoor unit. No additional OAT
(outdoor air temperature) sensor is required because the Infinity
Zone 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.
In a hybrid heat installation with a non--communicating heat pump,
an OAT sensor must be installed or the heat pump will not run.
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 Zone 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 Zone 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) MU ST be used to prevent
mixing the internal humidifier power with the indoor equipment
5
UIZ01--V
transformer. Applying 24VAC isolation relay coil to furnace or fan
coil HUM and COM terminals will allow the Infinity Zone 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.
