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 conditions the connection with
the pool automatically shuts off 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 the available solar radiation.
Follow the directions included with the automatic system components
for installing the differential
control and sensors. The 3-way valve is installed as shown in page 33
.
Important:
Make sure that the roof temperature sensor which is located on the roof is exposed to the
sun in the same way the collectors are. Position the sensor between two modules close to the glazing.

To avoid that both heaters and solar system will be operating in parallel, make sure that heater sensor is
installed
after
the solar system.
When the existing filtration pump is sufficient to deliver the desired discharge to the collectors, 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. If
the circulation pump is operated by a timer, make sure that the timer is set to work during solar radiation
hours.
