2. Introduction
The InfinityR System consists of several intelligent communicating components
which include the Infinity System Control (or User Interface), variable speed
furnace or FE fan coil, 2--stage AC and HP, (including Geothermal units),
multi--stage AC and HP, variable capacity HP and AC units, and Infinity System
Package units which continually communicate with each other via a four-- wire
connection called the ABCD bus. Commands, operating conditions, and other data
are p assed continually between components over the ABCD bus. The result is a
new level of comfort, versatility, and simplicity.
All Infinity 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 Infinity 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 System 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 Infinity S ystem Zone
board allows connection of a Carrier HRV or ERV without the need for separate
wall contro l o r NIM.
All system components are controlled through the wall mounted Infinity Sy stem
Control, which replaces the conventional thermostat and provides the homeowner
with a single wall control for all features of the system.
