FAN CO IL

The latest in technology makes the FE4A and FE5A fan coil
models the most advanced air handlers available. With attention to
quiet, efficient, and comfortable operation, Carrier has developed a
new benchmark for homeowner comfort and ease of installation.

The FE4A and FE5A utilize the Infinityt Control as a required
accessory to enable state of the art smart--diagnostics capability.
This enables faster troubleshooting, providing ease of service and
repair. The FE4A and FE5A also provide a 4--wire hook up with
matching outdoor unit and the Infinityt Control. This makes
installation simpler and a lot quicker than with conventional fan
coils. The FE4A and FE5A have advanced technology that allows
the fan coil to self--configure with a matching outdoor unit and the
Infinityt Control, cutting down on installation time. ArmorCoatt
provides a tin plating of the indoor coil’s copper hairpins. This
creates a barrier between the corrosion--causing elements and the
coil.

The FE4A and FE5A feature Puronr refrigerant, the chlorine--free
alternate that is the future for the residential heating and cooling
industry. The FE4A and FE5A using PuronR refrigerant maximize
performance for environmentally sound systems. In addition to
environmental safety, these systems are 30 to 40% more efficient
than standard heating and cooling systems, thereby combining
excellence in efficiency and environmental safety.

The FE4A and FE5A provide these benefits due to Carrier’s
command of Electronically Commutating Motor (ECM)
technology. These motors are extremely efficient at all speeds, and
enable the FE4A and FE5A to operate at the correct speed to
deliver airflow precisely, ensuring proper performance across a
wide range of duct static pressures. This adaptive efficiency also
makes installation quality easier to achieve for today’s demanding
homeowner.

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 FE4A and FE5A apart is the
factory--installed TXV, which enhances efficiency and provides
compressor--protecting operation at all recommended conditions.
Grooved copper tubing, louvered aluminum fins, and the large face
areas of the FE4A and FE5A refrigerant coils also provide superior
efficiency, for high SEER and HSPF performance.

Carrier leads the way in condensate control, a hallmark of these
multipoise 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.

For superior technology and unmatched comfort, the
environmentally sound and efficient FE4A and FE5A fan coils
can’t be beat.
