INTRODUCTION
The Infinity System consists of intelligent communicating components (User Interface, variable speed furnace or fan coil, AC or
HP), which continually communicate with each other via a
four-wire connection called the ABCD bus. Conventional 24-volt
signals on dedicated wires are not needed. Commands, operating
conditions, and other data are passed continually between the
components over the ABCD bus. The result is a new level of
comfort, versatility, and simplicity.
An Infinity System consists of a Infinity Control™ (thermostat
plus much more) and an Infinity furnace or fan coil. 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 dual capacity (communicating), or a
standard 24 vac 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 (NIM) allows connection of a
conventional 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 the
features of the system.
INSTALLATION AND START-UP OVERVIEW
This instruction covers installation of the Infinity Control™ only.
Physical installation instructions for the indoor, outdoor equipment
and accessories are provided with each unit.
Setup, commissioning, operation, and troubleshooting of the
Infinity System is covered only in this installation instruction. It is

INSTALLATION
STEP 1 — CHECK EQUIPMENT AND JOB SITE
INSPECT EQUIPMENT — File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
STEP 2 — INFINITY CONTROL™ LOCATION AND WIRING
CONSIDERATIONS
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.
INFINITY CONTROL™ LOCATION— The Infinity Control™
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™ 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 Infinity 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 Infinity 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 Infinity 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 Infinity 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 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
the installation.
Each 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, 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 configuration (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 Infinity Control™ location is accept-
able 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. 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 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. 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.

NOTE: Mercury is a hazardous waste and MUST be disposed of
properly.
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 inch 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 ¼ inch of insulation
from each wire.

8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram figures 12, 13
and 14.
A — Green = Data A
B — Yellow = Data B
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)
NOTE: It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consistently. A separate ABCD Connector comes inside packaging and
should be used when connecting to the furnace (or fan coil). (See
Fig. 10)

ELECTRICAL OPERATION HAZARD
Failure to follow this caution will result in equipment damage
or improper operation.
Improper wiring of the ABCD connector will cause the
Infinity Control™ 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 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. humidifier, ventilator, UV lights, etc.)
12. Turn on power to equipment.
EQUIPMENT WIRING DIAGRAMS:
See wiring diagram Figs. 12, 13 and 14.
NOTE: For other applications not listed, refer to the Network
Interface Module (NIM) Installation Instructions.
See wiring diagram figure 12 for a Typical Four-Wire Connection
Diagram, which includes an Infinity indoor communicating furnace or FE fan coil with a 2-speed Puron® communicating outdoor
unit. No additional OAT (outdoor air temperature) sensor is
required because the Infinity Control will use the temperature
sensor inside the 2-speed unit.
See wiring diagram figure 13 for a Typical Connection Diagram,
which includes an Infinity indoor communicating furnace or FE
fan coil, with a 1-speed air conditioning unit (non-communicating
outdoor). An Outdoor Air Temperature sensor may be installed
(not required) at the indoor furnace or fan coil OAT terminals.
When OAT is applied, the Infinity System will provide full system
features and benefits.
See wiring diagram Fig. 14 for a Typical Connection Diagram for
FE fan coil with a 1-speed heat pump (using non-communicating
outdoor unit). When OAT is applied, the Infinity System will
provide full system features and benenfits.

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 System
control humidifier operation.
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.
