High-efficiency pump Wilo-Varios PICO-STG, electronically controlled. Maintenance-free glandless circulator with screwed connection, blocking-current proof synchronous motor according to ECM technology and built-in electronic power control for variable differential pressure control. Can be used for all heating and air-conditioning applications, as well as for solar and geothermal systems.

Standard-equipped with:

Preselectable control modes for optimum load adjustment:
- Differential pressure constant (Δp-c), 3 pre-defined pump curves
- Differential pressure variable (Δp-v), 3 pre-defined pump curves
- Constant speed (3 speed stages)
- External control by iPWM GT (Heating/Geothermal) or iPWM ST (Solar) signal
Sync function (manual programming mode) for reprogramming the pump in the event of replacement
Manual pump venting function for venting the rotor chamber
Manual restart
LED display
- Display of selected control mode und pump curve
- Status display during venting and manual restart
- LED coding during the sync function
- Operation and fault display
Integrated motor protection
