Heat Pump Design

The Air Energy™ Heat Pump is one of the most
efficient ways to heat a pool or spa. The heat pump
transfers heat from the outside air to the pool or spa
water by means of an internal heat exchanger. See
Figure 20.
When the fan is turned on, warm air is drawn
through the refrigerant charged evaporator, turning
the cold liquid refrigerant to a warm gas. The gas then
flows through the compressor where it is compressed
resulting in a much higher temperature.
The hot gas enters the heat exchanger where the
water extracts the heat. The pump pulls in cool pool
water, which in turn converts the hot gas back into a
liquid refrigerant and starts the cycle over again.
NOTE The maximum heat output and effi ciency of a
heat pump is dependent upon the quality and
performance of the major components used.
As equally important are the environmental
conditions (for example, air temperature,
humidity, water temperature, and wind).

7.2 Heat Pump Components and Their
Operation
Evaporator - As air passes through the
evaporator, the refrigerant in the evaporator absorbs
heat from the ambient air. The warmer the ambient
air and the larger the surface area of the evaporator the
more heat it can collect
Fan - The Heat Pump fan produces high volume
airflow. Adequate airflow is required to transfer warm
air to the large evaporator.
Compressor - The compressor compresses the
refrigerant gas to a higher pressure, thus increasing the
temperature.
Heat Exchanger - As the final step to the heating
process, the heat exchanger transfers the heat from the
hot gas to the water. (Also known as a condenser.)
Reversing Valve - (For Units with Optional
Chiller) The reversing valve reverses the flow of the
refrigerant, which results in transferring cold gas to the
water, thus lowering the temperature.

Service Setup Options

The Service Setup options allow the installer to
change factory defaults of the select specific functions.
7.3.1

Maintain Temperature

1. Make sure the control is in the OFF mode.
2. To enter the Service Setup mode, press and
hold the MENU, POOL and SPA buttons for 5
seconds.
NOTE The display will revert back to OFF after one
minute since the last key press.
3. If connected, this option allows the heat pump to
control the pump even if the time clock has turned
the pump off. To select Maintain Temperature,
use the Up or Down button to display MAINTAIN
TEMP . Press the MENU button. The DISABLE
(default mode) appears, use the Up or Down
button to scroll to ENABLE , press the MENU
button to select. Press POOL or SPA to exit the
Service Setup mode.
7.3.2

Maintain Temperature Delay

1. Make sure the control is in the OFF mode.
2. To enter the Service Setup mode, press and hold
the MENU, POOL and SPA button for 5 seconds.
NOTE The display will revert back to OFF after one
minute since the last key press.
