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
