 You’ll
enjoy enhanced indoor weather with the revolutionary Comfort
Heat Pump System™. Carrier’s Comfort Heat Pump
System with our patented logic is a complete system that
consists of an outdoor heat pump, a variable speed fan coil
and our exclusive Thermidistat™ Control. These three
components interact to deliver exceptional year ’round
comfort. During the heating season, this system delivers
noticeably warmer air to your living areas and eliminates
uncomfortable drafts. During cooling operation, it can
dramatically reduce the amount of humidity inside your home.
Plus, you can enjoy more consistent temperatures, quieter
operation and money-saving energy efficiency all year long.
It’s exactly the kind of performance you’ve
learned to expect from Carrier, your indoor weather
experts.
 The
Comfort Heat Pump System delivers air that is significantly
warmer than air delivered by standard heat pump systems.
To maximize your comfort when the system first starts up,
the Comfort Heat Pump System delays the indoor blower until
the system can deliver warm air. This eliminates annoying
blasts of cool air during the cold, winter months. The
Comfort Heat Pump System also adjusts indoor airflow to
maximize your comfort, resulting in heating air temperatures
that are nearly 20º warmer than standard heat pumps.
And, to ensure that you aren’t disturbed by
uncomfortable drafts, the Comfort Heat Pump System delivers
this warmer air at a lower less drafty speed. The result is
a noticeably warmer, more comfortable home.

Temperatures indicated are for
heat pumps without PressureGuard, a feature of our
Puron heat pumps that allows for easier
installation for retrofit applications. Temperature
increases with PressureGuard are about 5 degrees
less than indicated. Regardless of how cold it gets
outside, this system delivers air temperatures
above 100 degrees.
|
Even on the coldest day of winter, your system will
continue to deliver warm, comfortable indoor weather.
That’s because the Comfort Heat Pump System adjusts to
changing conditions, inside and out. When the outdoor
temperature drops, your system’s auxiliary heater is
activated in stages on an as-needed basis, adjusting for the
perfect balance of consistent comfort and energy efficiency.
This is a vast improvement over typical auxiliary heaters
that can only be activated for a short period of time at
full blast, which creates wide temperature swings.
The difference in comfort levels is like comparing two
electric blankets. A standard auxiliary heater is like
an electric blanket that only has an off and high switch,
which you constantly have to turn off and on to stay
comfortable. The Comfort Heat Pump System is like an
electric blanket that has low, medium and high settings,
which automatically change depending on the temperature
inside your home.
It’s not the heat, it’s the humidity –
this old cliché is a reality when it comes to being
comfortable during the summer months. Moist, humid air
will cause you to be uncomfortable, even if the temperature
in your home is set at a reasonable level. With most
standard systems, the only way to remove unwanted humidity
is to set your thermostat to a very low temperature, which
often results in a cool, clammy home and high utility
bills.
Humidity can also cause your home to be a haven for
airborne pollutants that are too small to be seen.
Bacteria, dust mites, viruses and mold are a few examples of
items that thrive in a moist, humid house. Humid conditions
are also ideal for the growth of mildew and the formation of
musty smells. In addition, unchecked humidity can cause
damage to wood furniture and floors. By controlling the
humidity inside your home, you can improve your comfort
while protecting your home and furniture.

Investing in a system that can
maintain the ideal humidity will dramatically
improve your comfort. If the humidity in your home
is too high or low, it creates an ideal atmosphere
for the growth of mold, mildew, bacteria, and
viruses. The ideal relative humidity level for a
home is usually between 40 and 60 percent. As the
relative humidity in your home falls below or above
this range the climate becomes more conducive to
the issues listed in the chart. For example,
bacteria has a hard time flourishing when the
relative humidity inside your home is between 30
and 60 percent. At 60 percent relative humidity,
conditions are such that bacteria growth can occur.
As the relative humidity inside your home
increases, the atmosphere becomes more ideal for
the bacterial growth. This is shown in the graph by
the increased height of the blue bar. By investing
in a system that can control humidity, you can
enjoy a more comfortable home and protect the
investment you have already made in your home and
its contents.

The Comfort Heat Pump System™ delivers
exceptional, unmatched humidity control. It
automatically adjusts itself depending on the humidity level
inside your home. Most standard systems will cool your home
and turn off before they remove the excess humidity. This
allows the humidity in your home to continue to build. The
Comfort Heat Pump System has a patented humidity control
mode that allows the system to dehumidify your home, even
when it’s at the proper temperature.  This
results in up to 30 times more moisture being removed from
your home than a standard system. That’s over
1/2-gallon more moisture per hour being removed with the
Comfort Heat Pump System.
The indoor portion of your Comfort Heat Pump
System™ is a variable speed fan coil, which spreads
comfort evenly throughout your home when running on
continuous fan mode. Single speed fan coils can deliver
comfort to your home on an “all-or-nothing” basis.
You get either a full-speed blast of heating or cooling, or
you get nothing at all. As a result, when the system
isn’t running, warm air rises, cool air falls, and
temperatures can fluctuate by as much as 7º from floor
to ceiling. The continuous fan function of a variable speed
unit keeps the air moving and mixing throughout your home,
reducing the temperature difference from floor to ceiling to
as little as 2º. It’s like having a ceiling fan in
every room of your home.
|
When a system doesn't operate in
continuous fan, the air is able to stratify, with
warm air rising to the ceiling and cool air
dropping to the floor. This can cause as much as a
7° temperature difference from floor to
ceiling.
|
|
With continuous fan, the fan
continues to run at a lower rate even when the
system isn't heating or cooling your home. This
keeps the air in your home mixing and can reduce
the floor to ceiling temperature difference to as
little as 2°.
|
Continuous fan will also reduce the temperature
differences from room to room in your home. In
continuous fan, the system will continue to pull air into
the fan coil, mix it with air from other areas in the house
and then redistribute it. The result is more even
temperatures from room to room and between the first and
second floors.
|
|
|
With a typical system, the
indoor fan turns off when it isn’t heating or
cooling your home. By running the fan in continuous
mode, the system will continue to pull air from all
parts of your home, mix it, and then redistribute
it. This results in more consistent temperatures
room to room throughout your home. Since every home
is different, the actual impact of continuous fan
in your home will vary depending on the air ducts
in your home, how many windows you have, and other
appliances you have operating inside of your
home.
|
Continuous fan operation saves energy while helping to
create better indoor air quality. When you team your
Comfort Heat Pump System with an electronic air cleaner, the
continuous fan mode will help clean the air your family
breathes. The enhanced comfort and improved air quality are
achieved for less than the cost of operating a single light
bulb.
Carrier offers three different variable speed fan
coils: the FK4, 40FK and FV4. Each of these fan coils is
designed to communicate with the outdoor heat pump and the
Thermidistat Control and will automatically adjust its
airflow to maximize your comfort.
The FV4 is slightly different from the other two because
it uses Puron® refrigerant. Puron is the globally
accepted replacement for R-22, which is scheduled to be
phased out.
Carrier offers the broadest line of heat pumps in the
industry. Our premium WeatherMaker Two-Speed heat pump
provides superior comfort and efficiency. We also offer the
world’s first environmentally sound heat pump with
Puron refrigerant to help preserve the earth’s
protective ozone layer. Throughout our heat pump product
family, you’ll find a wide range of efficiency levels
and performance characteristics to choose from, including
models that operate quieter than a refrigerator. Your local
indoor weather expert can analyze your needs and present the
product combinations that will help you enjoy the benefits
of a Carrier Comfort Heat Pump System.
Carrier’s patented Thermidistat™ Control
puts superior comfort at your fingertips. With
Carrier’s Thermidistat Control, you take command of
both the temperature and the humidity level in your home. It
is available in either programmable or non-programmable
models and comes with convenient features such as:
Vacation Mode With just the touch of
a button, you can change from your normal temperature and
humidity schedule to settings more appropriate for times
when your home is unoccupied. Then, when you return, the
original settings are easily restored.
Easy-to-read-display This display is back
lighted to help you see the temperature.
Outdoor Temperature Sensor By pushing the
up and down buttons simultaneously, the outdoor
temperature is displayed.
Year-round comfort is provided by
Carrier’s Comfort Heat Pump System. The ICM2 motor
means increased efficiency, quieter operation and improved
control over your indoor weather, providing warmer airflow
when heating and controlling humidity when cooling.
Environmental responsibility and energy efficiency
of the FV4A are the advantages gained through use of Puron
refrigerant.
Customized comfort is set by your indoor weather
expert (your local Carrier dealer) using the Easy Select
Board.
Extra efficiency translates into lower utility
bills, thanks to design details such as the continuous fan
mode.
Quiet comfort for you and your family is one of
the benefits of our heavy-duty cabinet insulation.
Foil-faced insulation inhibits bacteria growth and is easy
to clean for better air quality.
Efficient, reliable operation translates into
performance you can count on because the Thermostatic
Expansion Valve (TXV) precisely meters the system’s
liquid refrigerant.
Improved indoor air quality is the result of the
enhanced drain pan that is contoured for superior drainage
of condensate.
Always look for these symbols,
the heat pump industry seals of certified performance,
efficiency and capacity.
