“Constant pressure control p-c” control mode: 1x pump, with pressure sensor

1

Activation point

2

Deactivation point

The pressure sensor detects the actual pressure value. The pump is switched on and off depending on the set thresholds:

  • If the pressure in the system falls below the activation threshold, the pump switches on.
  • If the deactivation threshold is exceeded, 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.
