2.1 I Operating principle
2.1.1 Cooling circuit
The heat pump heats the pool water and the air in the pool room/area. However, the two heating modes can not be used
at the same time. According to the temperature set by the user, the heat pump either heats the pool water, or heats
a water circuit designed to power the heating coil of a Zodiac® dehumidifier in order to heat the air. In the theoretical
event of a request for both at the same time, priority is given to heating the air.
However, if the pool temperature drops too significantly (-5°C compared to the setpoint temperature “SP01”), the heat
pump will revert to heating the pool water.

2.1.2 Pool water heating
The heat pump uses calories (heat) from the outside air to heat the pool water. The process to heat the pool water to the
required temperature can take several days, because it depends on the weather conditions, the pump heating capacity
and the difference between the water temperature and the required temperature.
The warmer and more humid the air, the better the heat pump performance.
Tip: improve and maintain your pool's temperature
•
Anticipate the commissioning of your pool far enough in advance before you use it.
•
Cover the pool with a sheet (bubble canopy, canvas, etc.) to prevent heat loss.
•
Take advantage of a period with mild outdoor temperatures (on average > 10°C at night). It will be even
more effective if it operates during the warmest hours of the day.
• Keep the evaporator clean.
•
Set the required temperature and leave the heat pump to run (adjusting the setpoint to maximum will
not heat the water more quickly).
2.1.3 Air heating
The heat pump also assists with the return of heat captured from the outside air to the dehumidifier water circuit which,
while flowing through the hot water coil in the dehumidifier, contributes to heating the air in the pool room/area. The
dehumidifier water circuit transports the heat captured by the heat pump to the dehumidification unit.
