5.9.2 Solar
The pool water will be heated with the solar to the set pool water temperature when this control is switched on. The user can therefore turn
off the solar by means of the on / off slider.
1. Delta T
Delta T determines the temperature difference between the solar temperature and the water temperature of the pool. With a Delta T= 3,
the valve will therefore only be activated when the solar temperature is higher than the pool water + 3 °C.
The valve will close again at a pool water temperature + 0.5°C.
2. Solar pumping speed
This is the minimum pumping speed with an activated solar valve. When the filter control is set to a low speed, but with solar the speed is
set to high, the pumping speed will take over the high speed when the solar valve is activated and then take over the low speed from the
filter control when the valve is deactivated again.
