22. IntroductionThe Infinityr System consists of several intelligent communicating componentswhich include the Infinityr Touch Control (or User Interface), variable speedfurnace or FE fan coil, 2--stage AC and HP, multi--stage AC and HP, and variablecapacity HP and AC units, which continually communicate with each other via afour--wire connection called the ABCD bus. Commands, operating conditions, andother data are passed continually between components over the ABCD bus. Theresult is a new level of comfort, versatility, and simplicity.All Infinityr System furnaces or fan coils are variable--speed and multi stage formaximum 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 beused.When using conventional single--stage outdoor units, the Infinity System furnace orfan coil provides the 24 volt signals needed to control them. When usingmulti--stage conventional outdoor units or heat pumps, an Infinity® SystemNetwork Interface Module or ”NIM” (P/N SYSTXCCNIM01) may be required toprovide additional control outputs. Also, the NIM allows connection of a CarrierHRV or ERV without the need for separate wall control.When using a Carrier HRV or ERV with a zoned system, the Infinityr SystemZone board allows connection of a Carrier HRV or ERV without the need forseparate wall control or NIM.All system components are controlled through the wall mounted Infinity TouchControl, which replaces the conventional thermostat and provides the homeownerwith a single wall control for all features of the system.3.
