3.8.2. Hydraulic connection of the motorized 3-way valve
In the "automatic" position, the motorized 3-way valve, installed on the swimming pool's filtration circuit and
controlled by the DualSun BS/2 solar control, will direct the water towards the solar collectors, provided that the
temperature difference between these and the swimming pool water is not lower than the value indicated by the
"Temperature difference" thermostat and that the desired temperature has not yet been reached.
Otherwise, the water from the filtration circuit will be conducted directly to the swimming pool, without going
through the solar collectors.
