The most versatile replacement pump of all time.
The Wilo-Varios PICO-STG is the universal solution for replacement heating, air conditioning and cooling systems for residential use. In addition to providing standard and external control operation, the settings of the replaced pump can be easily adopted thanks to the synchronization assistant. Thanks to its compact design and synchronization function, the characteristic curves of the old pump can be adopted, making installation and commissioning extremely easy. It is also very comfortable to use thanks to the green button technology.
Features/Product benefits
- Compact design, new control types (such as iPWM) and synchronization assistant make it the perfect replacement solution for all applications, including solar and geothermal energy.
- Maximum ease of use thanks to the LED display and Green Button Technology with a button for regulation operation and a button for setting the pump.
- Easy installation thanks to compact design, adaptable electrical connections and maintenance functions such as air purge
- Highest operational and usage safety thanks to proven technology
Construction
Glandless rotor circulation pump with screw connection, anti-blocking current EC motor and integrated electronic performance regulation.
