Carrier’s command of ECM technology may be most evident in the comfort advantages that an ECM can deliver. For true comfort, the homeowner can achieve command of both temperature and humidity in cooling and heating modes. Another feature which sets the FE4B apart is the factory-installed TXV, which enhances efficiency and provides compressor-protecting operation at all recommended conditions. Grooved tubing, louvered aluminum fins, and the large face areas of the FE4B refrigerant coils also provide superior efficiency, for high SEER2 and HSPF2 performance. Carrier leads the way in condensate control, a hallmark of these multi-poise fan coils. All of these featured components are protected within a rugged, pre-painted metal cabinet lined with super-thick, high-density insulation. For neat, high quality installations, the unit exterior features sweat refrigerant connections for simple leak free performance, and multiple electrical entry for both high and low voltage service. Assembled at the factory compliant with low leak requirements of less than 2% cabinet leakage rate at 0.5 inches W.C. and 1.4% cabinet leakage rate at 0.5 inches W.C. when tested in accordance with ASHRAE 193 standard. FEATURES Smart Diagnostics • Self configuring (ease of installation) • Easier troubleshooting, providing faster service and repair • Energy Tracking capability with the Infinity Wall Control. (Energy Tracking has the ability to monitor and estimate the energy consumption of your Infinity system.) • Compatibility with wall control depends on software version. Check the installation instructions for minimum requirements.
