1. Safety Considerations
Improper installation, adjustment, alteration, service, maintenance, or use can cause
explosion, fire, electrical shock, or other conditions which may cause death,
personal injury or property damage. Consult a qualified installer, service agency or
your distributor or branch for information or assistance. The qualified installer or
agency must use factory--authorized kits or accessories when modifying this
product. Refer to the individual instructions packaged with the kits or accessories
when installing.
Follow all safety codes. Wear safety glasses, protective clothing, and work gloves.
Have a fire extinguisher available. Read these instructions thoroughly and follow
all warnings and cautions included in literature and attached to the unit. Consult
local building codes and the current edition of the National Electrical Code (NEC)
NFPA 70. In Canada, refer to the current editions of the Canadian Electrical Code
CSA C22.1.
Recognize safety information. When you see this symbol on the unit and in
instructions or manuals, be alert to the potential for personal injury. Understand the
signal words DANGER,WARNING,andCAUTION. 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 hazards, 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.
2. Introduction
The InfinityrSystem consists of several intelligent communicating components
which includes the InfinityrTouch Control (or User Interface), variable speed
furnace or FE fan coil, and 2--stage AC or HP, which continually communicate with
each other via a four--wire connection called the ABCD bus. Commands, operating

2
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 Infinityrfurnaces 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 Infinityr
(communicating), or a standard single--stage 24VAC controlled outdoor unit may be
used.
When using conventional single--stage outdoor units, the Infinity furnace or fan coil
provides the 24 volt signals needed to control them. Also, the InfinityrNetwork
Interface Module (P/N SYSTXCCNIM01) allows connection of a Carrier HRV or
ERV without the need for separate wall control.
When using a Carrier HRV or ERV with a zoned system, the InfinityrZone board
allows connection of a Carrier HRV or ERV without the need for separate wall
control.
All system components are controlled through the wall mounted Infinity Touch
Control, which replaces the conventional thermostat and provides the homeowner
with a single wall control for all features of the system.
3. Quick Start
3.1. Set Time and Date
From the main screen, touch MENU, on the bottom of the control. The
TIME/DATE icon allows you to set the time and date for the InfinityrTouch
Control.
dTo set the HOUR, MINUTE, MONTH, DAY, or YEAR touch the feature
you wish to change.
dUse the Up (Y) and Down (B) buttons to make the appropriate changes.
dWhen you have completed all of the settings touch SAVE.
