Even more convenience, even less power consumption

A visible symbol of the new generation of high-efficiency pumps for heating and air-conditioning systems in residential dwellings is the green operating button, which together with new functions provides maximum convenience in commissioning and maintenance. Defaults for radiators or underfloor heating – symbolised by pictograms – save time during commissioning. The energy efficiency was improved once more and the power consumption is thus even lower and always in view. And thanks to the more compact construction, pump replacement is now even easier.

Your advantages
