STARTUP
Before starting the device please read the previous
sections, especially "Hydraulic Installation" and "Elec-
trical connection".
Follow next steps:
1. Connect the devices to the power supply and press EN-
TER
to just one device to remain the other device in OFF
possition.
2. Set the pump rated current intensity value:
- Press
during 3 seconds.
- The current intensity value is displayed on screen and
LED A is flashing (factory setting 16A).
- By mean of
and
ted in the characteristics plate of the motor. See Note 1.
- Press
for validation.
3. Set the cut-in (start) pressure.
- Press
during 3 seconds.
- The start pressure value is displayed on screen and LED
START is flashing.
- By mean of

from 0,5 to 5,5 bar. See Table 1
- Press
for validation.
4. Set the maximum pressure of the installation.
- Open a tap.
- Take the provided allen key.
- Turn the regulation screw clockwise to increase the out-
let pressure and anticlockwise to decrease it (factory set-
ting: 3 bar). Look at the maximum pressure viewer (Fig.
D) while turning the screw to have a fisrt aproximation of
the outlet pressure setting.
- Close the tap and do the final adjustment looking at the
display pressure reading.

5. Repeat the process for the other device. Remember to
press ENTER to the configured device to go to OFF possi-
tion.
Both devices must have the same cut-in pressure and
maximum pressure setting.
Finally, press ENTER to the OFF possition device and open
a tap to check the communication. Notice that the first
start will be done by both DPR and after that, they will
start the alternation and cascade opperation.
