Wilo-Varios PICO-STG сirculation pump with wet rotor, with threaded connection, resistant to current block synchronous motor according to ECM technology and integrated electronic power control unit for smooth adjustment of the pressure drop. Can be used for all heating and air conditioning systems, as well as for solar and geothermal plants.
Pre-selection control methods for optimal load setting:
- Constant pressure drop (Δp-c), 3 predefined characteristic curves;
- Changeable pressure drop (Δp-v), 3 predefined characteristic curves;
- Constant number of revolutions (3 degrees of number of revolutions);
- External control via iPWM GT signal (heating/geothermal energy) or iPWM ST (solar power);
- Sync function (manual programming mode) for reprogramming the pump when replacing;
- Manual venting function for the rotor chamber ventilation;
- Manual restart;
- LED indication;
- Indication of the selected control method and characteristic curve;
- Status indication for venting and manual restart;
- LED coding during Sync function;
- Malfunctioning or failure indication;
- Built-in engine protection;
- Auto unlock function;
- Electric plug-in cable with 3-pole plug connection and with Wilo-Connector connection;
- PWM connection;
- Pump casing with Cataphoresis coating
