Automatic systems (Private & public pools)
The basic difference between the manual system just outlined and an automatic system is the use of
a motorized 3-way valve, which is controlled by two sensors. In cloudy weather the connection
with the pool is automatically shut off so as to maintain the warmest temperature possible. The two
sensors will read: (1) temp of cool water coming from the pool and (2) the heat of available solar
radiation.
Important:
Make sure that the radiation sensor which is located on the roof is exposed to
the sun in the same way the collectors do. In a windy region a transparent plastic cover can
be installed over the sensor.
Private pool basic plumbing
When the existing filtration pump is sufficient to deliver the desired discharge to the collectors and there is
no need for additional booster pump, the system plumbing and control is based on the existing pump and a
motorized 3 way valve that directs the pool water to the collector when there is sufficient sun radiation.
