• Installation and operating instructions

6 Description and function

• The control device protects the pump against dry run and controls the start/stop
cycles of the pump according to the flow/pressure conditions of the installation.
• The device is screwed onto the pressure port of the pump or onto the pressure
pipe. It is designed in-line, meaning that both ports are on the same axis.
• The yellow LED (pos. 9) is lit: the pump is switched on and ready for operation, the
extraction points are closed and the operating pressure is maximum. The device
includes a small compensation chamber with water. Its volume is variable, thanks
to a diaphragm that is kept under tension by a spring. When a valve is opened in
the installation, water flows from the small chamber to the pressure pipe and thus
lifts a floater. The green LED (pos. 10) lights up when the pump operates normally.
• The signalling and control elements on the cover are (Fig. 2):
- Yellow LED = mains voltage is present, ready for operation (pos. 9),
- Green LED = pump is operating (pos. 10),
- Red LED = fault, any fault leading to pressure loss in the pipe system (pos. 11),
- RESET = reset key (pos. 8). After checking and rectification the fault, press this
key until the pressure is restored in the unit. This is also valid for the first start-
up. When the start-up pressure is not high enough, the pump goes directly into
malfunction.
