Anyone heating their pool via a solar absorber faces a control task: the water should only run across the absorber field when there is actually heat to be gained there. That is exactly what the SC04 solar controller does – a complete set consisting of a control unit, temperature sensors and an electrically actuated Praher…
The Aquastar family from Praher automates the 6-way backwash valve of the sand filter system: instead of turning a lever by hand, a motorised lift-and-turn actuator switches the valve automatically between the positions Filter, Backwash, Rinse, Circulate, Drain, Winter position and Closed. Within the family there are four controllers with very different profiles: Aquastar easyII,…
