The Wilo Yonos Pico electronic heating and air-conditioning circulator has an integrated electronic power control system for continuously adjusting the differential pressure. The constant Δp-c and variable Δp-v differential pressure modes can be selected according to the application, such as radiators or underfloor heating. The green button makes installation and maintenance easier.

This wet-rotor circulator features an ECM motor, automatic unblocking, high starting torque and a rotor chamber venting function. The LED display shows the selected setpoint and current power consumption in W. The package includes 1 & 1/4" circulator unions.
