“Drain” control mode: 1x well, 1x pump, 2x float switches or electrodes
ON | Switch-on level |
OFF | Switch-off level |
DR | Dry-running level |
When the fill level in the well rises and the switch on-level is reached, the pump switches on. The well is drained. When the switch off level is reached, the pump switches off after the set switch-off delay has elapsed.
To protect the pump from a dry run, install an additional float switch or electrode in the well:
- If the water level falls below the dry running level, the pump switches off. An error message appears on the display and an alarm sounds.
- If the dry-running level is exceeded, the alarm and error message are automatically reset.
