SAFETY
This product must be installed and serviced by a qualified installer or
service agency. Improper installation, adjustment, alteration, service
or maintenance can cause injury or property damage.
HOW YOUR SYSTEM WORKS
COOLING CYCLE
If your hand is wet and you blow on it, it feels cool because some of the
moisture is evaporating and becoming a vapor. This process requires
heat. The heat is being taken from your hand, so your hand feels cool.
That’s what happens with an air conditioner. During the cooling cycle,
your system will remove heat and humidity from your home and will
transfer this heat to the outdoor air.
HEATING CYCLE (HEAT PUMPS)
During the heating cycle, your system will remove heat and humidity
from the outdoor air and will transfer this heat to your home. This is possible because even 0°F outdoor air contains a great deal of heat.
Remember that your heat pump doesn’t generate much heat, it merely
transfers it from one place to another.
System Operation
Your thermostat puts full control of the comfort level in your home at
your fingertips. DO NOT switch your thermostat rapidly ON and OFF or
between HEAT to COOL. This could damage your equipment. Always
allow at least 5 minutes between changes.

SETTING THE THERMOSTAT
The main power to the system must be kept ON at all times to prevent
damage to the outdoor unit compressor. If necessary, the thermostat
control switch should be used to turn the system OFF. Should the
main power be disconnected or interrupted for 8 hours or longer, DO
NOT attempt to start the system for 8 hours after the power has been
restored to the outdoor unit. If heat is needed during this 8 hour
period, use emergency heat.
THERMOSTATS
YOUR KEY TO COMFORT
Although thermostats may vary widely in appearance, they are all
designed to perform the same basic function: to control the operation of
your air conditioning or heat pump system. Regardless of size or shape,
each thermostat will feature a temperature indicator; a dial, arm, or
push button for selection of the desired temperature; a fan switch to
choose the indoor fan operation; and a comfort switch for you to select
the system mode of operation.
Only approved thermostats have been tested and are fully compatible
with this equipment. Please be aware that many different thermostats
operate on batteries or “power stealing” principals. These types of thermostats can not be supported as trouble free when used with this product.
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a programmable electronic type thermostat.
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.

NOTICE
A complete operating instruction is provided by the manufacturer for
each thermostat. Familiarize yourself with its proper operation to obtain
the maximum comfort with minimum energy consumption.
The computerized electronic thermostat is actually a sophisticated electronic version of a manual change-over type. This thermostat includes
features which allow “set-back” temperature variations for periods of
sleep, or while you are away during the day, and means energy savings
for you. The thermostat also features a digital clock.
COOLING ONLY
If your air conditioning system is designed to provide cooling only (AC),
with no capability for heating operation (heat pump), a two-stage cooling only thermostat, with a manual, one-position “Cool” and “Off” comfort switch is all that is required for system operation.
COOLING AND HEATING (HEAT PUMP)
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a programmable electronic type thermostat with 2-stages of cooling and 2stages of heat.
MANUAL CHANGE-OVER
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.
PROGRAMMABLE ELECTRONIC
THERMOSTATS
The computerized electronic thermostat is actually a sophisticated electronic version of a manual change-over type. This thermostat includes
features which allow “set-back” temperature variations for periods of
sleep, or while you are away during the day, and means energy savings
for you. The thermostat also features a digital clock.
FAN OPERATION SELECTION
A multi-position fan switch allows you to choose the type of fan operation of the indoor fan.
AUTO
With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cooling. This position will provide
the lowest operating cost. If you purchased one of our thermostats, they
have an Intelligent fan mode which continually circulates the air during
occupied modes or when you are at home, and can cycle the fan during
unoccupied mode or during the night while you sleep to further conserve energy.
ON
CONTINUOUS FAN OPERATION: With the thermostat fan switch set to
“ON”, the indoor fan will not shut off. However, the cooling (AC) or heating (heat pump) systems will still operate as required by room temperatures. This provides continuous air filtering and more even temperature
distribution to all conditioned spaces.
FAN ONLY OPERATION: On moderate days, usually during spring and
fall, when neither heating nor cooling is required, you may want to run
only the fan to ventilate, circulate and filter the air in your home or building. Set the comfort control switch to “OFF” and the fan switch to “ON”.
Be sure to return the switches to their original positions for normal operation.
START-UP
The maximum and minimum conditions for operation must be observed
to assure a system that will give maximum performance with minimum
service.
TABLE 1:

The comfort control switch is assumed to be in the “OFF” position. If the
main power supply to the outdoor and indoor units is off, turn the appropriate disconnects to the “ON” position. Place the system into operation
as follows.
1. Set temperature adjustment to the desired temperature on your
COOLING - The higher the setting, the lower the amount of energy consumed. Federal Guidelines recommend a setting of 78 °F.
HEATING - The lower the setting, the lower the amount of energy consumed. Federal guidelines recommend a setting of 65 °F or lower.
If your cooling and heating temperature adjustments are separate, be
sure to set both.

SYSTEM OPERATION
MANUAL CHANGE-OVER THERMOSTAT
COOLING YOUR HOME: With the comfort control switch in the
“COOL” position, the system will operate as follows: When the indoor
temperature rises above the level indicated by the temperature adjustment setting, the system will start. The outdoor unit will operate and the
indoor fan will circulate the cooled, filtered air. When the room temperature is lowered to the setting selected, the system will shut off.
HEATING YOUR HOME: If your system includes a heating unit and the
comfort control switch is in the “HEAT” position, the system will operate
as follows: When the indoor temperature drops below the level indicated by the temperature adjustment setting, the system will start. The
heating system will operate and the indoor fan will circulate the filtered
air. When the room temperature rises to the setting selected, the system will shut off. Whether heating or cooling, the fan will continue to
operate if the fan switch was set in the “ON or Intelligent” position. The
“AUTO” setting on the fan switch will allow the fan to shut off when your
system does.
ELECTRONIC THERMOSTAT
The computerized electronic thermostat, when programmed, will function automatically to operate the system as follows: When the indoor
temperature rises above the higher (COOL) setting, the outdoor unit will
operate and the indoor fan will circulate the cooled, filtered air. When
the room temperature is lowered to the selected level, the system will
shut off. The indoor fan will either shut off or run continuously, depending upon your choice of fan switch setting. When the indoor temperature drops below the lower (HEAT) setting, the heating system will
operate, and the indoor fan will circulate the heated, filtered air. When
