FE4A

PREMIUM ENVIRONMENTALLY SOUND

FAN COIL

The FE4A is the premium air handler combining the proven

technology of Bryant fan coils with the environmentally sound

refrigerant, Puron®. The FE4A achieves an operation

advantage because the ECM (Electronically Commutated

Motor) combined with a Quantum Plus heat pump with Puron is

highly efﬁcient at all possible operating speeds, and delivers the

precise amount of airﬂow desired over a wide range of duct

static pressure conditions.

The FE4A comes with state of the art smart diagnostics

capability. This enables faster troubleshooting providing ease of

service and repair. The FE4A also provides a 4-wire hook up

with matching outdoor unit and the Evolution Control. This

makes installation simpler and a lot quicker than with

conventional fan coils. The FE4A’s advanced technology allows

the fan coil to self-conﬁgure with a matching outdoor unit and

the Evolution Control, cutting down on installation time.

Other features homeowners appreciate are quiet operation of

the FE4A, including the soft ramp up at the beginning of a

heating or cooling cycle, and its soft ramp down when the duty

cycle is complete. Annoying sounds from sudden changes in

airﬂow are reduced for worry free comfort. When used in

continuous fan mode, the FE4A can operate quietly at very low

levels of airﬂow for gentle reduction of temperature differences

between areas of the home and within each individual room

from ﬂoor to ceiling. In addition, when used in conjunction with

Bryant air cleaners, the FE4A provides continual cleansing of

the air while quietly operating in continuous fan duty, for the best

in indoor air quality.

The FE4A is loaded with other popular features. The

Thermostatic Expansion Valve (TXV) reliably meters refrigerant

at all operating conditions during cooling mode providing

excellent compressor protection. Grooved copper tubing,

louvered aluminum ﬁns, and the large face areas of the FE4A

refrigerant coils provide superior efﬁciency, for high SEER and

HSPF performance. Robust, corrosion resistant and highly

draining condensate pans provide for excellent condensate

control. All components are protected within a rugged,

prepainted metal cabinet lined with super thick, high density

insulation and vapor barrier. The unit exterior features sweat

refrigerant connections for simple leak free performance,

multiple electrical entry for both high and low voltage service to

simplify installation. Field-installed heaters are also available,

ranging from 5-kw to 30-kw.

For the best in efﬁciency and Environmentally Sound operation,

comfort, ease of installation and reliable performance, the FE4A

can’t be beat.

The Bryant FE4A is a premium communicating variable-speed fan coil designed for use with Puron® refrigerant, offering an environmentally sound solution for heating and cooling systems. This fan coil is engineered to provide superior efficiency, comfort, and ease of installation, making it a robust choice for residential applications.

Function Description

The primary function of the FE4A is to serve as the indoor component of a split-system heating and cooling system, working in conjunction with a matching outdoor unit (such as a Quantum Plus heat pump with Puron). It circulates conditioned air throughout the home, providing both heating and cooling as required. The variable-speed ECM (Electronically Commutated Motor) is central to its operation, allowing the fan coil to precisely adjust airflow to meet the demands of the system and maintain optimal comfort. This precise airflow control contributes to high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) performance, ensuring energy-efficient operation.

The fan coil is designed to self-configure with a matching outdoor unit and the Evolution Control, simplifying the installation process and reducing setup time. This intelligent communication allows the system to operate as a cohesive unit, optimizing performance across various operating conditions.

Usage Features

The FE4A offers a range of features designed to enhance user comfort and convenience:

Quiet Operation: Homeowners will appreciate the quiet operation, which includes a soft ramp-up at the beginning of a heating or cooling cycle and a soft ramp-down when the duty cycle is complete. This minimizes annoying sounds often associated with sudden changes in airflow, contributing to a more peaceful indoor environment.
Continuous Fan Mode: When operating in continuous fan mode, the FE4A can run quietly at very low airflow levels. This gentle circulation helps to reduce temperature differences between areas of the home and within individual rooms, from floor to ceiling, promoting more consistent comfort throughout the living space.
Enhanced Indoor Air Quality: When paired with Bryant air cleaners, the FE4A facilitates continuous cleansing of the air. Its quiet operation in continuous fan mode makes it an ideal component for maintaining high indoor air quality without intrusive noise.
Precise Refrigerant Metering: The Thermostatic Expansion Valve (TXV) reliably meters refrigerant across all operating conditions during cooling mode. This ensures excellent compressor protection and efficient heat transfer.
High-Efficiency Coils: The refrigerant coils feature grooved copper tubing and louvered aluminum fins, along with large face areas. These design elements contribute to superior efficiency, supporting high SEER and HSPF performance.
Robust Condensate Control: The unit is equipped with sturdy, drainable, and corrosion-resistant condensate pans, ensuring excellent control over condensate. These pans are designed to handle condensate disposal in conditions more rigorous than those specified by the Air Conditioning and Refrigeration Institute.
Installation Flexibility: The FE4A is designed for installation flexibility, with multipoise capabilities that allow for various configurations. It also includes horizontal hanging provisions on the cabinet. Multiple electrical entry points for both high and low voltage service further simplify installation.
Accessory Heaters: Field-installed accessory heaters are available, ranging from 5-kW to 30-kW, providing additional heating capacity as needed. These heaters are designed for easy plug-in installation.
Humidifier Ready: The unit is ready for humidifier integration, allowing for enhanced humidity control within the home.
Advanced Cabinet Design: The cabinet is constructed from galvanized, pre-painted metal and is lined with super-thick, high-density insulation and a vapor barrier. This robust construction protects all internal components and features innovations designed to prevent cabinet sweating. The unique cabinet design also meets stringent regulations for air leakage, achieving a 2% leakage rate when tested at 1.0 inches of static pressure.
Sweat Refrigerant Connections: The unit exterior features sweat refrigerant connections, ensuring simple and leak-free performance.
Wiring Options: Entry options for both high and low voltage wiring hook-up are provided, further simplifying electrical connections.
Transformer Protection: A simple, 5-amp blade fuse (with a spare included) protects the 40 VA transformer.

Maintenance Features

The FE4A incorporates several features to facilitate easier maintenance and troubleshooting:

Smart Diagnostics: The unit comes with state-of-the-art smart diagnostics capabilities. This allows for faster troubleshooting, making service and repair easier and more efficient.
Easy Filter Access: The fan coil includes a factory-supplied, cleanable, and reusable filter. The newly improved filter rack features added insulation for an improved air seal. Servicing the filter requires no tools, making routine maintenance quick and convenient.
Easy Coil Inspection: For models with A-coils, inspection is made easy with a removable, snap-in plug.
