Wilo-Varios PICO-STG high-efficiency pump, electronically regulated. Maintenance-free wet rotor recirculation pump with threaded connection, self-protected synchronous motor according to ECM technology and integrated electronic power control for modulating differential pressure regulation.


 

Can be used in all heating and air-conditioning applications, as well as for all geothermal and solar energy systems.


 

Preselectable control modes for optimal load matching:

• Constant differential pressure (?p-c), 3 preset characteristic curves
• Variable differential pressure (?p-v), 3 predefined characteristic curves
• Constant speed (3 speed stages)
• External control with iPWM GT (heating/geothermal) or iPWM ST (solar) signaling
  
   

Advantages:

• Sync operation (manual programming mode) for resetting the pump to factory conditions in case of replacement
• Function for manual rotor compartment ventilation
• Manual restart
• LED indicator
• Indication of selected control mode and characteristic curve
• Status indication during aeration and manual restarting
• LED coding during sync operation
• Indication of operation or failure
• Integrated motor saver
• Automatic unlock function
• Electrical connection cable with three-pin socket and Wilo-Connector
• PWM connection
• Pump body treated with cataphoresis
