Wilo-Yonos PICO

Even more convenience, even less power consumption.

Your advantages
Wilo-Yonos PICO

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. Default settings 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 is shown alternating with the flow. And thanks to the more compact construction, pump replacement is now even easier.

Your advantages

  • Maximum operating convenience owing to the Green Button Technology with new, intelligent settings, intuitive user interface and new functions
  • Optimised energy efficiency owing to EC motor technology, settings with an accuracy of 0.1 m and display of current power consumption
  • Quick and easy installation and smooth exchange owing to the new, optimised construction
  • Easy maintenance and high degree of operational reliability due to automatically and manually triggered restart or pump venting function
  • Maximum operational reliability owing to proven technology
