Typical Thermostat Operation
Your thermostat is the control center for your Split System. It is very important that the thermostat be located where it
can best “sense” the average room temperature. It must not be located where it is exposed to hot or cold drafts or to
hot or cold spots on the wall, such as those received from outside walls, walls with pipes inside, or from openings into
the attic. Because of the wide variety of programmable thermostats available, we cannot describe how all of them
work. However, a typical thermostat has two switches: a SYSTEM switch and a FAN switch.
WARNING
To avoid possible equipment damage, personal injury, fire or death, the
following instructions must be observed regarding unit location, air
requirements and operating procedures.
The SYSTEM switch can include settings of HEAT,
OFF, COOL, AUTO:
EMERGENCY
HEAT – EMERGENCY HEAT is only used with heat
pumps. Emergency heat means the com-
pressor (i.e., the outdoor unit) is turned off,
and your backup source (if present) will pro-
vide heat when the temperatures in the
room falls below the temperature selected.
(No matter how warm the room becomes,
cooling will not be provided.) The backup
source is usually electricity, but it may be a
gas or oil furnace. The EMERGENCY HEAT
setting may be used if you suspect a prob-
lem exists with the heat provided by the
compressor, but your dealer is not able to
service it immediately. With some comfort
systems, the EMERGENCY HEAT setting
may also be used to provide a quicker
warm-up of the room. Once the warm-up is
completed, you should usually return the
system switch to the HEAT or AUTO setting.
If you leave the system switch in the EMER-
GENCY HEAT setting, it may increase your
operating costs.
HEAT – Your comfort system provides heat when
the temperature in the room falls below the
temperature selected. No matter how warm
the room becomes, cooling will not be pro-
vided.
OFF – Your comfort system will not provide heating
or cooling, no matter how cold or hot the
room becomes.
COOL– Your comfort system provides cooling when
the temperature in the room rises above the
temperature selected. No matter how cold
the room becomes, heat will not be pro-
vided.
AUTO– Your comfort system will provide heat when
the temperature in the room falls below the
temperature selected, and will provide cool-
ing when the temperature in the room rises
above the temperature selected. With most
of these thermostats, you will have a tem-
perature range in which neither heating or
cooling is being provided. The AUTO set-
ting will help your building avoid tempera-
ture extremes, but it may increase your
operating costs.
NOTE: Keeping your windows closed whenever the
thermostat SYSTEM switch is in the HEAT, COOL or
AUTO setting will keep operating costs down.

some comfort systems, the indoor fan may
continue to run for a short time after the
compressor shuts off. With most gas fur-
naces, the indoor fan will start a short time
after the burners are lit, and will keep run-
ning for a short time after the burners shut
off. When your comfort system is not heat-
ing or cooling, the fan will not run.

Typical Thermostat Operation
IMPORTANT: Keep light bulbs and other heat sources
away from the thermostat. Heat from these items may
cause the thermostat to falsely register the temperature
of the room as warm when in actuality it may be quite
cold.
CAUTION
Do not exceed the set point limits preset at the
factory. As shipped from the factory, your comfort
system is designed to provide cooling only when the
outdoor temperature is 55°F or higher. Exceeding
these limits may result in severe equipment
damage.
Residential room thermostats must be exposed to the
air in the room in order to accurately control room
temperature. It must not be covered. Thermostats used
in commercial buildings however can be covered if
approved thermostat guards are used. If you need a
thermostat guard for your commercial building, contact
your dealer or another qualified servicer.
In some commercial applications or in a few homes, you
may need cooling indoors even when the outdoor
temperature is less than 55°F. If you do, discuss it with
your dealer before operating your comfort system during
cool weather.
Some comfort systems will include a programmable
thermostat. If your system does not include a program-
mable thermostat, you may want to discuss it with your
dealer. Programmable thermostats can automatically
switch to a more economical temperature setting when
your building is unoccupied or you are sleeping. Pro-
grammable thermostats automatically switch to a more
comfortable temperature setting at the time you have
previously selected. A programmable thermostat can
reduce operating costs without substantially reducing
comfort.
In most homes, these limits will not cause problems. To
avoid potential problems, you may want to remind
children not to play with the thermostat.
CAUTION
Over adjusting or “jiggling” the thermostat switch will
cause the compressor on the outdoor unit to turn on
then off, then quickly on again. Eventually this will
cause a blown fuse, a tripped circuit breaker, and/or
a damaged compressor. Do not move the

temperature selector on the thermostat for at least
five minutes after the compressor has shut off.

General Information
Electrical Power Supply
Refrigerant
Many outdoor units include a crankcase heater. This
small heater warms the oil in the compressor for im-
proved lubrication. Once the needed temperature has
been reached, most of these heaters will shut off
automatically.
Your comfort system uses R-410A refrigerant. R-410A
does not contain chlorine and will not harm the ozone
layer in the atmosphere. It is classified as an HFC
(Hydrofluorocarbon).
The EPA has approved R-410A under its Significant
Alternative Policy (SNAP) guidelines. R-410A is envi-
ronmentally “friendly” as it does not harm the ozone
layer in the atmosphere. R-410A systems are the
recognized replacement for R-22 systems in residential
applications.
These heaters work effectively, but not rapidly. If your
outdoor unit has a crankcase heater and the power has
been disconnected from your outdoor unit for more than
two hours, you must connect electrical power to the
outdoor unit for at least four hours before setting the
thermostat so as to cause the unit to come on.
When your comfort system is operating properly, the
refrigerant is contained within airtight passages. No
refrigerant escapes into the atmosphere during normal
operation.
Not all outdoor units have crankcase heaters. If you are
not certain whether yours does or not, contact your
dealer.
If your outdoor air conditioning (not heat pump) unit
does have a crankcase heater, you may wish to shut it
off in the fall after cooling season is completely over. To
do this, simply open the disconnect switch which is near
the outdoor unit, or turn the proper circuit breaker at the
electrical panel to the OFF position. This could save you
a small amount of your winter electrical bills. If you
choose to do this, remember - a four hour warm-up
period with the electrical power connected is necessary
before running the air conditioner again in the spring. If
you forget this warm-up period, you run the risk of
severe equipment damage.
When repair or replacement of your comfort system
becomes necessary, it is essential that you hire a
qualified servicer to perform the work. A qualified
servicer will have the tools and training necessary to
ensure that EPA regulations are followed. U.S. residents
who ignore or intentionally violate the EPA regulations
are in violation of the law, and may be subject to fines or
other penalties.

Maintenance
Annual Maintenance
CLEAN OUTSIDE COIL (QUALIFIED SERVICER
ONLY)
We strongly recommends your unit be given an annual
maintenance checkup by a qualified servicer. Your unit
should be inspected by a qualified installer or service
agency at least twice a year. This check should be
performed before the heating and cooling seasons
begin. This will ensure that your unit operates at
maximum efficiency. Particular attention should be paid
to the following items. Repair as necessary.
WARNING
To avoid personal injury or death due to electrical
shock, disconnect the electrical power before
cleaning the coil(s).
• Check physical support of the unit. Ensure it is
sound without any sagging, cracks, or gaps,
around the base.
DISCONNECT ALL ELECTRICAL POWER TO THE
INDOOR AIRHANDLER OR FURNACE BEFORE
REMOVING ACCESS PANELS TO PERFORM MAIN-
TENANCE. Disconnect power to both the indoor and
any outdoor units. NOTE: THERE MAY BE MORE
THAN ONE ELECTRICAL DISCONNECT SWITCH.
• Check for obvious signs of deterioration of the unit.
• Check electrical connections for tightness and/or
corrosion. Check wires for damage.
ALTHOUGH SPECIAL CARE HAS BEEN TAKEN TO
MINIMIZE SHARP EDGES IN THE CONSTRUCTION
OF YOUR UNIT, BE EXTREMELY CAREFUL WHEN
HANDLING PARTS OR REACHING INTO THE UNIT.
• Check that filters are clean and in the proper
placement in the unit or duct system.
Routine Maintenance
Air must be able to flow through the outdoor unit of your
comfort system. Do not construct a fence near the unit
or build a deck or patio over the unit without first dis-
cussing your plans with your dealer or other qualified
servicer. Restricted airflow could lead to poor operation
and/or severe equipment damage.
REPLACE OR CLEAN INDOOR FILTER
IMPORTANT NOTE: Never operate unit without a filter
installed as dust and lint will build up on internal parts
resulting in loss of efficiency, equipment damage and
possible fire.
Likewise, it is important to keep the outdoor coil clean.
Dirt, leaves, or debris could also restrict the airflow. If
cleaning of the outdoor coil becomes necessary, hire a
qualified servicer. Inexperienced people could easily
puncture the copper tubing in the coil. Even a small hole
in the tubing could eventually cause a large loss of
refrigerant. Loss of refrigerant can cause poor operation
and/or severe equipment damage.
An indoor air filter must be used with your comfort
system. A properly maintained filter will keep the indoor
coil of your comfort system clean. A dirty coil could
cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace,
in a blower unit, or in “filter grilles” in your ceiling or
walls. The installer of your air conditioner or heat pump
can tell you where your filter(s) are, and how to clean or
replace them.
Do not use a condensing unit cover to “protect” the
outdoor unit during the winter, unless you first discuss it
with your dealer. Any cover used must include “breath-
able” fabric to avoid moisture buildup.
Check your filter(s) at least once a month. When they
are dirty, clean or replace them.
You may want to ask your dealer about high efficiency
filters. High efficiency filters are available in both elec-
tronic and non-electronic types. These filters can do a
better job of catching small airborne particles.
COMPRESSOR
The compressor motor is hermetically sealed and does
not require additional oiling.
MOTORS
Indoor and outdoor fan motors are permanently lubri-
cated and do not require addtional oiling.

Before Calling Your Servicer
There are several built-in safety features that may automatically shut off the unit under abnormal operating condi-
tions. If your system does not operate normally, take time to perform the following checks before requesting service.
A couple of simple checks may allow you to avoid a service call. If the following steps do not resolve the problem,
contact a qualified servicer for further troubleshooting and/or repairs. Do not attempt troubleshooting beyond that
which is outlined below.
•
•
Check the thermostat to confirm that it is properly set.
Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor
operation for awhile, and then reset automatically. Also, some power companies will install devices which shut
off air conditioners for several minutes on hot days. If you wait several minutes, the unit may begin operation
on its own.
•
Check the electrical panel to see if any circuit breakers have tripped or fuses have failed. If they have, you may
reset the circuit breaker(s) or replace the fuse(s) once without calling a servicer.
CAUTION
To avoid the risk of fire or equipment damage, install the same amperage circuit breaker or fuse as you are
replacing. If the circuit breaker or fuse should open again within thirty days, contact a qualified servicer to correct
the problem. If you repeatedly reset the breaker or replace the fuse without having the problem corrected, you run
the risk of severe equipment damage.
•
Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.
•
Check the outdoor unit to confirm that it has not been covered on the sides or the top. If it has been covered by
a large object that you can easily remove, you may do so without calling a servicer. If it is covered with dirt or
debris, call a qualified servicer to clean it.
•
•
Check the indoor air inlets and outlets to confirm that they are not blocked by rugs, curtains, or other objects; or
have not been accidentally closed. If air cannot get into a room, the room will not be comfortable.
If airflow through all the air outlets seems low, check the filter. If it is dirty, clean or replace it.
