Function:

1.

Starts and Stops the pump automatically.

2.

It protects the pump against damage caused by dry running.

3.

The pressure switch starts the pump for 15 seconds, if it is connected to the voltage
source. If the pressure in the line system drops, the pump is restarted. In the case of the
conventional systems with pressure switch & pressure tank, the pump stops running if a
certain pressure level is achieved. In contrast to this, the pressure switch stops depending
on the flow rate. In doing so it d

elays the pump’s switching off for a few seconds (7 to 15

seconds) to minimize the number of pump starts.

LED-indication:

1. The upper (1st) LED (Alarm) blinks: the automatic unit is off due to lack of water (protection

against dry running), press

„Restart“ to start the unit again.

2.  The middle (2nd) LED blinks: the pump is switched on.
3.  The lower (3rd) LED blinks: the switch has voltage
4.  Restart (Reset)

– restart button
