Disassociation of devices
To dissociate a device belonging to an existing group, go to page AS (installer menu) of the device itself and press the – key for at least 5
seconds.
After this operation all the icons related to the connected devices will be replaced the message "No Dev" is shown and the COMM LED will
remain off.
Replacing devices
To replace a device in an existing group it is sufficient to dissociate the device to be replaced and to associate the new device as described in
the procedures above.
If it is not possible to dissociate the element to be replaced (faulty or not available), you will have to carry out the disassociation procedure for
each device and create a new group.
8.5.6 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
esybox, see paragraph 11.1.12 Controll Wireless.
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.
8.5.7 EK: low pressure detected on suction
The EK parameter allows you to set the functions for detecting low suction pressure as follows:
function disabled
•
function enabled with automatic reset
•
function enabled with manual reset
•
The function for detecting low pressure on suction generates the blocking of the system after the time T1 (see T1: Low pressure delay).
When the block occurs, the F4 symbol is displayed on the main page.
The two different settings (automatic or manual reset) differ in the type of reset once the pump is blocked:
In automatic reset mode the suction pressure must return to a value above the PK threshold for at least 2 seconds.
•
In manual reset mode it is necessary to simultaneously press and release the "^" and "˅" keys.
•
8.5.8 PK: low pressure threshold on suction
Sets the pressure threshold below which the block is tripped for low pressure on suction.
direction of rotation
8.5.9 RT:
Displays the direction of rotation. Parameter that cannot be modified by the user.

8.6 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", "SET" and "^"keys until "TB" appears on the display (or use the selection menu
pressing ^ 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.
8.6.1 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 lacking, the electropump will take a certain time to reload, supply the flow
and put the plant under pressure.
