What is a Hybrid?
VRF Limitations
• Expensive
• Sweat connections
• Computer design required
• No efficiency label today
• Increased labor to install
The blending of a complex VRF system with the simplicity of a
multi-zone system to create a new hybrid solution that shares
the best of both systems.
Why Flex?
The ability to create the right combinations, the right quantity
(up to 8-zones), the right style indoor units, and the right
capacity. It’s the right choice for your home or business.
Why Inverter?
An Inverter is a system that controls the rotational speed (not
just an ON/OFF signal) of an electric motor by adjusting the
frequency and voltage of the electrical power supplied to the
motor. The inverter constantly regulates the compressor speed
to its optimum energy usage, producing higher refrigerant
performance with less power consumption.
HFI
• Long piping
• Better value
• SEER rated
• Flare connections
• Easier installation
• 4-way outdoor
unit connection
130% Connectable Capacity (AOU48RLXFZ1 Only)
The HFI system is rated at 48,000 BTUs but you can connect
up to 130%, or 62,000 BTUs of rated indoor unit capacity to the
AOU48RLXFZ1. Connectable capacity allows you to connect
indoor units that can exceed outdoor unit capacity. However, if
you connect indoor units that exceed 100% of the outdoor unit’s
capacity there are limitations.
HFI
• 130% capacity
• Up to 8 zones
• Central remote
• Lower copper
tubing costs
• Miswiring
detection
BENEFITS
Multi-Zone Limitations
• Shorter piping length
• Fewer number of zones
• No central remote control
• No over connectable
capacity
If all indoor units are cooling or heating at the same time, the system
will limit their capacity so that their total matches the outdoor unit’s capacity.
When a zone meets a desired set temperature it requires less capacity. The
unused capacity is then distributed to the remaining indoor units, increasing their capacity.
For Example: The load on a small 2-story office building with a business downstairs and worker apartments
upstairs is 62,000 BTUs (38,000 BTUs downstairs and 24,000 BTUs upstairs) but the workers aren’t upstairs
and downstairs at the same time, therefore not all units will be running simultaneously allowing 100% heating
or cooling to occupied spaces.
HFI vs. Multi vs. VRF
AHRI defines VRF as having three main features: (1) a variable speed compressor, (2) a computerized control
individual zoning system and (3) optimized refrigerant path of installation.
TYPICAL INVERTER MULTI-ZONE
• Variable speed compressor
• Computerized zone control
• With the expansion valves mounted
in the outdoor unit, it does not have
an optimized refrigerant path.
• 2 outdoor
units needed
• No separation
tube assemblies needed
Halcyon Hybrid Flex Inverter
• Variable speed compressor
• Computerized zone control
• Remotes expansion valves from the
outdoor unit to mid-stream in the
refrigerant piping, creating a semioptimized refrigerant path.
TYPICAL INVERTER VRF SYSTEM
• Variable speed compressor
• Computerized zone control
• Expansion valves are mounted either
within or near the indoor unit, and
engineered piping maximizes
compressor efficiency to create an
optimized refrigerant path.

Individual Zoning: Personalized Whole Home Comfort
Halcyon HFI Systems are some of today’s most advanced forms of heating and air conditioning. Multi-zone outdoor
units can operate from 2 to 8 indoor units simultaneously. Fujitsu’s HFI Systems are super quiet as well as highly
energy efficient. Choose from 4 indoor unit styles.
Wall Mounted
They mount high on a wall, out of sight and do not
require ductwork, increasing energy efficiency.
Quiet operation
Easy maintenance
High delivered efficiency means lower utility bills
Slim Duct
Mounted in a ceiling or in a framed enclosure below a
ceiling. They use minimal ductwork and remain very
energy efficient.
Concealed and out of sight
Look of central air with the efficiency of a mini-split
Less ducts = higher efficiency
Compact Cassette
Cassettes are extremely discreet, with only the grille
showing in the ceiling. They use the latest fan
technology to distribute the conditioned air evenly.
Wired remote control (wireless is optional)
Powerful turbo fan operation
Fits into a standard 2’ x 2’ ceiling grid
Floor Mounted
Floor mount systems are ideal for residential radiator
replacements or any room with limited upper wall space,
like a kitchen or sunroom.
Compact size fits easily under a standard window
Features twin airflow for improved heat delivery
Designer wireless remote control

Built In Filtration
Long-life+ Ion Deodorization Filter
The filter deodorizes by powerfully
decomposing absorbed odors using
the oxidizing and reducing effects of
ions generated by the ultra-fineparticle ceramic.
Apple-Catechin Filter
Dust, mold spores and microorganisms are absorbed onto the
filter by static electricity and growth
is inhibited and deactivated.
+ The filter can be used for approximately 3 years if it is washed with water when dirty to restore it's surface action.
* Features vary by model and therefore standard wireless remote controls should be used with the models they are
associated with.
** Feature of models ASU18, 24RLF only.
