Varios PICO-STG 25/1-8 -130
Item no. : 4232744

Your advantages
  • The most compatible replacement solution for all applications, including solar and geothermal, thanks to compact design, innovative control modes (such as iPWM) and the Sync assistant
  • Maximum operating convenience thanks to its LED display and Green Button Technology featuring a button for control mode and a button for setting the pump
  • Easy installation owing to a compact design, adjustable Electrical connections and maintenance functions such as venting
  • Maximum operational reliability based on proven technology
The most versatile replacement pump of all time.

The Wilo-Varios PICO-STG is the universal replacement solution in the heating, air conditioning and cooling sector for residential dwellings, as well as for solar and geothermal installations. It offers either standard mode or external control mode, and the settings of the pump it replaces can be easily imported using the Sync assistant. Its compact construction and the adoption of characteristic curves from the old pump with the new synchronisation function make installation and commissioning particularly easy. And with the Green Button Technology the operability is highly convenient.

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 replacement owing to the new, optimised construction
  • Easy maintenance and high degree of operational reliability thanks to automatically and manually triggered restart or pump venting function
  • Maximum operational reliability thanks to proven technology
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.
