Product Data 58CVA/CVX InfinityTM 80 Variable Speed 4-Way Multipoise Furnace THE INFINITY® 80 GAS FURNACE The InfinityTM 80 Variable-Speed, 4-way Multipoise Gas Furnaces offer unmatched comfort with ComfortHeatTM technology and IdealHumidityTM in an 80% AFUE gas furnace. You get all the benefits of a ComfortHeat technology furnace: reduced drafts, reduced sound levels, longer cycles, less temperature swings between cycles, and less temperature differences between rooms.
With the variable speed blower motor, homeowners can now economically run constant fan to help eliminate temperature differences throughout the house and to get better indoor air quality. This IdealHumidity furnace also increases comfort in the summer by wringing out extra humidity when needed. The Infinity 80 furnaces are approved for use with natural or propane gas, and the 58CVX is also approved for use in Low NOx Air Quality Management Districts. Carrier InfinityTM System When the Infinity 80 variable-speed gas furnace is matched with the Infinity Control and an air conditioner or heat pump, you will experience the ultimate in ComfortHeat and Ideal Humidity through unparalleled control of temperature, humidity, indoor air quality, and zoning. The Carrier Infinity System also provides unprecedented ease of use through on-screen, text-based service reminders and equipment malfunction alerts. For even greater comfort and convenience, match the Infinity 80 furnace with an Infinity air conditioner or heat pump. This will create a fully communicating system, requiring only 4 thermostat wires between system components, and troubleshooting can even be done in the future from the outdoor unit without entering the home. Optional remote access through telephone or Internet is also available when combined with a remote connectivity kit.
