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 provides maximum convenience in commissioning and maintenance.

The energy efficiency was improved once more and the power consumption is thus even lower and shown on the LED display. And thanks to the more compact construction, pump replacement is now even easier.
