maintain the pool at the temperature setpoint.
Example: When the temperature setpoint is 28°C, if the water temperature rises to 30°C, the heat
pump will automatically switch to "COOLING" mode to return to the temperature setpoint. If the water
temperature falls to 27 °C, the heat pump will automatically switch to "HEATING" mode to return to the
