Evaluating the pump operating time
The installer can display the pump operating time by pressing the "Test" key
of the product to easily come to a conclusion concerning the tightness of the
entire system.
The green pilot lamp provides information on the last 5 days. The pump oper-
ating time is indicated as a total.
A flash of one second of the green pilot lamp corresponds to a pump operat-
ing time of a total of one day during the last five days.
If the green pilot lamp (A) lights up very briefly, this indicates that the pump
operating time during the last five days was proportionally shorter.
Troubleshooting
1. Hold down the Test key.
- After five seconds, the
A
green pilot lamp (A) indi-
cates the pump operat-
B
ing time.
If you open the device, the
yellow LED (C) on the printed
circuit board always displays
the pump operating time (you
do not need to press the Test
key).
