The temperature of the pool water and the absorber is constantly controlled by two separated
temperature sensors. In case the temperature of the absorber is 4 °C (fixed set-up) higher than
the pool water, a valve or a pump is activated to pump the water through the absorber to be
heated by solar radiation. When the absorber is cooled down by the water and water is not
heated any longer, the pump automatically switches off or the automatic valve cuts off the
water flow, water is heated again by solar radiation.
The alternating activation and deactivation of the absorbers is repeated until the adjusted
nominal temperature is reached (see page 13). In case of higher temperature, the absorber
remains closed.
