HOW TO OPERATE
YOUR HEAT PUMP
The control center for your Heat Pump is your thermostat.
Many different types are used, but they are similar to
operate.
Your thermostat will have switches to select some or all of
the following functions.
COOL - Turns cooling on when temperature rises above
set point.
HEAT - Turns Heat Pump heating on when temperature
drops below set point. If room temperature drops another
2°, turns on the auxiliary resistance heat. Heat pump con-
tinues to run.
AUTO - Turns on cooling or heating as required to maintain
set points. Most thermostats have at least 4° separation
between heating and cooling settings.
OFF - Turns heating and cooling modes off (Fan may still
run in FAN-ON).
FAN-ON - Turns fan on for continuous operation.
FAN-AUTO - Fan cycles on and off with cooling or heating
operation.
EMERGENCY HEAT - Turns Heat Pump compressor and
outdoor fan off and provides heat from electric strips only.
Use this switch to manually turn the Heat Pump off and
change to the auxiliary heat in case of Heat Pump pro-
blems.
A lever is used to set the temperature that you desire.
Some thermostats have two levers, one for heating and
one for cooling.
Lights may be used to indicate that the auxiliary electric
heat is operating. The lights may be different colors on dif-
ferent types of thermostats. Typical lights will be blue or
green for normal auxiliary heating and red for emergency
heat.
For the most economical operation of your system, select
the highest summer setting and the lowest winter setting
at which you are comfortable. Typical temperatures are
78° on cooling and 70° on heating. Your operating cost is
increased from 3% to 8% for each degree lower setting in
cooling and for each degree higher setting in heating.
When heating, let the Heat Pump do the work whenever
possible. Do not change temperature settings more than
necessary. If you turn the temperature setting up 2° or
more you will bring on the auxiliary resistance heat. This
costs more to operate than the Heat Pump.
NIGHT SETBACK THERMOSTATS
Night Setback thermostats are available to automatically
turn the temperature down at night and back up in the morn-
ing. Only Setback thermostats with gradual, incremental
or “Intelligent” recovery should be used with Heat Pumps.
Setback thermostats without gradual recovery will use the
electric strip heaters to warm the air in the morning, and
may use more electricity than was saved during the night.
Ask your contractor for advice before installing a Setback
or “Energy Saving” thermostat.
HEAT PUMP MONITOR
A control called a Heat Pump Monitor may be installed
with your system. If so, it will check the performance of
your Heat Pump and turn it off if a problem occurs. It will
switch to the auxiliary heat and turn on the Emergency
Heat Light on your thermostat to tell you that the system
requires attention.
OPERATING ECONOMICALLY
Here are other ways to save electricity and improve your
system’s performance.
1. Keep all grilles and registers open and clear of
obstructions such as drapes or furniture.
2. Keep doors and windows closed.
3. Be sure all air ducts are well insulated and sealed with
a vapor barrier.
4. Let the sun in during the winter. Keep it out during the
summer.
5. Be sure clothes dryers are vented to the outside. (Away
from your outdoor unit.)
6. Fireplaces are pleasant, but most fireplaces bring in
more cold outside air for combustion and flue draft
than they heat. Your Heat Pump may actually run
more!
7. Use kitchen and bathroom exhaust fans only when
necessary.
8. Add insulation, storm windows and insulated outside
doors. Seal cracks to prevent air leakage.
9. Keep your filters clean. Reduced air flow in your unit
reduces efficiency.
10. Operate your indoor fan on AUTO. It costs less and will
provide better humidity control in the summer.
11. Keep lamps, TV’s and other heat sources away from
your thermostat.
12. Leave the power on at the outdoor unit at all times. If
