Wilo-Varios PICO-STG

Series description

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.

Construction

Glandless circulator with screwed connection, blocking-current proof EC motor and integrated electronic power control.

Application

All hot-water heating systems, air-conditioning applications, industrial circulation systems, primary circuits of solar and geothermal systems.
