tion of several similar networks existing within the radius of
action of the wireless without creating ambiguity; in this way
the user does not see the elements that do not belong to his
pumping system.
From this menu page it is possible to associate and disassociate an ele-
ment from your personal wireless network.
When the machine starts the AS menu item does not show any connec-
tion because no device is associated. Only an action by the operator can
allow devices to be added or removed with the operations of association
and disassociation.
Association of devices
Pressing '+' for 5 sec puts the machine into the mode where it searches
for wireless association, communicating this status by the blinking of the
icon (related to the device on which the action is carried out) and of the
COMM leds at regular intervals. As soon as two machines in a working
communication range are put into this status, if possible, they are associ-
ated with each other. If the association is not possible for one or both
machines, the procedure ends and a pop-up appears on each machine
saying "association not possible". An association may not be possible
because the device you are trying to associate is already present in the
maximum number or because the device to be associated is not recog-
nised.
The search status for association remains active until the device to be
associated is detected (irrespective of the result of association); if not
device can be seen within the space of 1 minutes, the machine automati-
cally leaves association status. You can leave the search status for wire-
less association at any time by pressing SET or MODE.
Disassociation of devices
To disassociate an element you must first select it with the "+" or "-" keys,
then press - for 5 s; this puts the system into device disassociation mode
in which the icon of the selected device and the COMM led start to flash
rapidly, indicating that the device chosen will be cancelled. The next time
- is pressed the device will be disassociated; instead, if you press any
key or let more than 30 sec elapse from entering disassociation mode,
the procedure will be terminated.

7.5.6 - PR: Remote pressure sensor

The PR parameter is used to select a remote pressure sensor.
The default setting is with no sensor present.
In order to execute its intended functions, the remote sensor must be
connected to a control unit, which in turn must be associated to the
e.sybox, see point 5.1 - Operation with control unit
As soon as a connection is established between the e.sybox and control
unit and the remote pressure sensor has been connected, the sensor
starts operating. When the sensor is active, the display shows an icon of
a stylised sensor with a P inside it.
The remote pressure sensor operates in synergy with the internal sensor
so that the pressure never falls below the setpoint pressure in either of
the two points in the system (internal and remote sensors). This allows
compensation for any pressure drops.
NOTE: in order to maintain the setpoint pressure in the point with lower
pressure, the pressure in the other point may be higher than the setpoint
pressure.

7.6 - Technical Assistance Menu

Advanced settings to be made only by skilled personnel or under the
direct control of the service network.
From the main menu, hold down simultaneously the "MODE" and "SET"
keys until "SP" appears on the display (or use the selection menu press-
ing + or -). The menu allows you to view and modify various configuration
parameters: the MODE key allows you to scroll through the menu pages,
the + and – keys allow you respectively to increase and decrease the
value of the parameter concerned. Press SET to leave this menu and
return to the main menu.

7.6.1 - TB: Water lack blockage time

Setting the reaction time of the water lack blockage allows you to select
the time (in seconds) taken by the device to indicate the lack of water.
The variation of this parameter may be useful if there is known to be a
delay between the moment the motor is switched on and the moment it
actually begins to deliver. One example may be a plant where the suction
pipe is particularly long and there are some slight leaks. In this case the
pipe in question may be discharged and, even though water is not lack-
