“Constant pressure control p-c” control mode: 1x pump, with pressure switch
1 | Activation point |
2 | Deactivation point |
The pressure switch used detects the actual pressure value and defines the activation and deactivation threshold:
- 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.
