Your heat pump is a unique, all weather comfort-control
appliance that will heat and cool your home year round and
provide energy saving comfort. It’s often not recognized
that heat is always in the air, even when the outside
temperature is below freezing. The heat pump uses
this basic fact of physics to provide energy saving heat
during the winter months. For example, If the outdoor
temperatureis47°F(8°C),yourheatpumpcandeliver
approximately 3.5 units of heat energy per each unit of
electrical energy used, as compared to a maximum of
only 1 unit of heat energy produced with conventional
electric heating systems.
In colder temperatures, the heat pump performs like an air
conditioner run in reverse. Available heat energy outside
the home is absorbed by the refrigerant and released
insidethehome.Thisefcientprocessmeansyouonly
pay for “moving” the heat from the outdoors to the indoor
area. You do not pay to generate the heat, as with more
traditional means of heating.
During summer, the heat pump reverses the flow of the
heat-absorbing refrigerant to become an energy-efficient,
central air conditioner. Excess heat energy inside the
home is absorbed by the refrigerant and released outside
the home.
OPERATING INSTRUCTIONS
Thermostat styles vary.Please referto the thermostat
manufacturer’s User manual for detailed programming
instructions.
1.Setthethermostat’ssystemmodetoCOOLandchange
thefanmodetoAUTO.
2. Set the temperature selector to the desired temperature
level.Theoutdoorfan,compressor,andblowermotorwill
all cycle on and off to maintain the indoor temperature
at the desired cooling level.
NOTE: If the temperature level is re-adjusted, or the
system mode is reset, the fan and compressor in the
outdoor unit may not start immediately. A protective
timer circuit holds the compressor and the outdoor
fan off for typically 3 to 5 minutes following a previous
operation or the interruption of the main electrical power
before restarting.
3. When the difference between temperature setpoint
and actual room temperature is relatively small, the
unit will operate at stage 1 and a lower indoor blower
air flow rate is used. When that temperature difference

will operate at one or more different speeds in each of

Many thermostats include a system operating mode called
EmergencyHeat(abbreviatedEMHTorAUXHT,etc).In
this mode, heating is provided solely by the backup means
(electricstripheatorgasfurnace),andtheheatpump
isnotused.Thismaytypicallybeselectedbytheuser
when there is a problem with the heat pump equipment,
when the outdoor temperature is too low for heat pump
operation, or for any other reason or preference. Some
thermostats automatically revert to backup heating means
under certain conditions. Refer to the thermostat manual.
TheuserisadvisedtoavoidusingEmergencyHeatexcept
under exceptional circumstances, since the energy costs
are likely to be significantly higher than with the heat pump
During cold weather heat pump operation, the outdoor unit
will develop a coating of snow and ice on the heat transfer
coil.Thisisnormalandtheunitwilldefrostitself.Thisunit
features Demand Defrost that monitors ambient and coil
temperatures to regulate the defrost function accordingly.
At the beginning of the defrost cycle, both the outdoor
condenser fan and compressor will turn off. After a brief
delay, the compressor will turn on and begin to heat the
outdoor coil causing the ice and snow to melt. NOTE:
While the ice and snow is melting, some steam may rise
from the outdoor unit as the warm coil causes the melting
frost to evaporate. When defrost is completed, the outdoor
fan motor will start, and the compressor will turn off again.
After a brief delay, the compressor will start up again and
continue normal operation.
