WILO Stratos PICO, electronically controlled high efficiency pump

Maintenance-free glandless circulation pump with screwed connection, blocking-current proof synchronous motor using ECM technology (up to 90% energy saving compared to an uncontrolled pump) and built-in electronic power control for variable differential pressure control. Can be used for all HVAC applications (+2 °C to +110°C). Control mode can be selected in accordance with the radiator/underfloor heating application.

Standard-equipped with:

Preselectable control modes for optimum load adjustment: Δp-c (differential pressure constant), Δp-v (differential pressure variable) can be combined with Dynamic Adapt control function
Automatic setback operation
Integrated motor protection
Operating and fault display (with error codes)
LC display with precise menu navigation
Display of the instantaneous power in Watts, or
display of the current flow in m³/h
Display of the cumulative power consumption in kilowatt-hours
Reset function for resetting the electricity meter or for resetting the settings to the factory settings
"Hold" function (key lock) for disabling the settings
Minimal consumption only 3 W
High efficiency, TÜV tested (the certificate can be seen at www.wilo.com/legal)
Compact design
Automatic deblocking function
High starting torque
Venting routine for automatic venting of the rotor chamber
Equipped as standard with a thermal insulation shell
