Introduction; Quick Start - Carrier SYSTXCCITN01-A Installation Instructions Manual

2. Introduction

The Infinityr System consists of several intelligent communicating components
which include the Infinityr Touch Control (or User Interface), variable speed
furnace or FE fan coil, 2- - stage AC and HP, multi- - stage AC and HP, and variable
capacity HP and AC units, 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 Infinityr System 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 Infinityr System
(communicating), or a standard single- - stage 24VAC controlled outdoor unit may be
used.
When using conventional single- - stage outdoor units, the Infinity System furnace or
fan coil provides the 24 volt signals needed to control them. When using
multi- - stage conventional outdoor units or heat pumps, an Infinity
Network Interface Module or "NIM" (P/N SYSTXCCNIM01) may be required to
provide additional control outputs. Also, the NIM 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 Infinityr
Zone board allows connection of a Carrier HRV or ERV without the need for
separate wall control or NIM.
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.
