The result isa new level of comfort, versatility, and simplicity.All Infinity furnaces or fan coils are variable--speed and multi stagefor maximum flexibility, efficiency, and comfort. They supportcontrolled ventilation, humidification, dehumidification, and airquality control. Either an Infinity (communicating), or a standard24VAC controlled outdoor unit may be used.When using conventional outdoor units, the Infinity furnace or fancoil provides the 24 volt signals needed to control them. Also, theInfinity Network Interface Module (P/N SYSTXCCNIM01) allowsconnection of a Carrier HRV or ERV without the need for aseparate wall control.All system components are controlled through the wall mountedInfinity Control, which replaces the conventional thermostat andprovides the homeowner with a single wall control for all featuresof the system.
