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 Network Interface Module (P/N SYSTXCCNIM01) 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 Control, which replaces the conventional thermostat and
provides the homeowner with a single wall control for all features
