association at any time by pressing SET or MODE.
Disassociation of devices
To dissociate a device belonging to an existing group, go to page AS (in
-
staller 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.
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 con
-
nected 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 con
-
trol 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.
IMPORTANT:
Once the association has been made between 2 or
more devices, a pop-up appears on the display asking you to extend
the configuration. This happens in the case where the devices have
different configuration parameters (e.g. setpoint SP, RP etc.). Pressing
+ on a pump extends the configuration of that pump to the other as
-
sociated pumps. When the + key is pressed pop-ups appear with the
message “Wait…”, and when this message is finished the pumps will
start to work regularly with the sensitive parameters aligned; refer to
paragraph 9.4.5 for further information.
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 com
-
pensation 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 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.
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 lacking,
the electropump will take a certain time to reload, supply the flow and put
the plant under pressure.
7.6.2 - T1: Low pressure delay (kiwa function)
Sets the time when the inverter switches off after receiving the low pressure
signal (see Setting low pressure detection par. 7.6.15.5). The low pressure
signal can be received on each of the 4 inputs by suitably configuring the
input (see Setup of auxiliary digital inputs IN1, IN2, IN3, IN4 par 7.6.15).
T1 can be set between 0 and 12 s. The factory setting is 2 s.
