ABOUT YOUR HEAT PUMP
SYSTEM
Identifying Your System
Your new Carrier Heat Pump system is what we call a "split
system." It has an outdoor unit and an indoor unit connected to
each other with copper tubing called refrigerant lines. Each of
these units has a rating plate with the model and serial numbers
you will need to reference when calling an authorized Carrier
dealer about your system.
Take a few moments now to locate those numbers and record
them in the spaces provide on the cover of this booklet.
USING YOUR NEW CARRIER
SYSTEM
Your Carrier Heat Pump system is controlled by a thermostat
inside your home. Because there are so many thermostats
available, please refer to the owner's manual supplied with your
thermostat or indoor unit for complete details on system
operation. Or, read the next section for basic operating
instructions.
SYSTEM OPERATION WITH
BASIC THERMOSTAT
Most basic thermostats have three main controls:
• System or Mode Control: Typically offers the following
selections: Cool. Off. and Heat. Some thermostats also have
Auto, which lets the system switch between heating and
cooling as needed.
• Temperature Control: A button, lever, or set of buttons that
allows you to select the temperature inside your home.
• Fan Control: Typically offers two options: Auto and On.
"Auto" provides slightly higher energy efficiency by
circulating air only during cooling (or heating) operation.
"On" provides better air circulation, better dehumidification
and better air cleaning by running the system's blower
continuously.
HEATING YOUR HOME
For heating operation, make sure the System or Mode control is
set for Heating. Then, adjust the Temperature control to your
desired setting. Finally, use the Fan control to select Automatic
(turns on and off as heating is needed) or On (runs continuously).
Depending on your typical heating needs, your home comfort
system may also include a supplementary heating source that will
automatically turn on as needed. You may also select this heat
source manually if desired.
COOLING YOUR HOME
For cooling operation, make sure the System or Mode control is
set for Cooling. Then, adjust the Temperature control to your
desired setting. Finally, use the Fan control to select Automatic
(turns on and off as cooling is needed) or On (runs continuously).
