SAFETY
AWARNING
This product must be installed and serviced by a qualified installer
or service agency. Improper installation, adjustment, alteration, ser-
vice 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 pos-
sible 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
[ CAUTIONJ
The main power to the system must be kept ON at all times to pre-
vent damage to the outdoor unit compressor. If necessary, the ther-
mostat 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 dur-
ing 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 ther-
mostats 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 pro-
grammable 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.
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 elec-
tronic 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 cool-
ing only thermostat, with a manual, one-position "Cool" and "Off" com-
fort 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 pro-
grammable electronic type thermostat with 2-stages of cooling and 2-
stages of heat.
MANUALCHANGE-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.
