• Replacement solution with the most complete compatibility for a variety of applications, including solar and geothermal systems, thanks to its compact design, new control methods (such as iPWM) and synchronization assistant
• Maximum ease of operation thanks to LED display and green button technology with push button for control mode and push button for pump setting
• Easy installation thanks to compact design, adjustable electrical connections and maintenance functions such as venting
• Highest operating and maintenance safety due to well-proven technology
• The replacement pump is the most universal pump available today.
• The Wilo-Varios PICO-STG is a universal replacement solution for heating, air-conditioning and refrigeration systems in single- and two-family houses. It provides standard and external adjustment modes, and with the help of a timing assistant, the settings of the replaced pump can be easily applied. The compact design, applying the characteristics of the old pump with the new timing function greatly simplifies installation and commissioning. And the "green button technology" provides the highest level of operating convenience.
