NOTA: for all the units that must operate in CASCATA, pa-

MASTER
Once the cascade function has been activated, it is possible to set
the unit in Master mode by setting parameter c03 to the value 1
To function correctly, the cascade function requires the fol-
lowing parameters to be set on the MASTER:
c01: with this parameter it is possible, if the function is enabled,
to select the desired cascade level
c02: set the parameter = 1
c03: set the parameter = 1 (MASTER)
c04: the number of units present in the cascade (master +
number of slaves)
c05: The number of units to keep on when the minimum opera-
ting level is requested
c06: The number of units to keep on when the medium opera-
ting level is requested
c07: The number of units to keep on when the maximum ope-
rating level is requested
NOTA: parameters c04, c05, c06, c07, c08 must be set only
on the MASTER unit. If set on the SLAVE units they have no
effect.
SLAVE
To function correctly, the cascade function requires the fol-
lowing parameters to be set on the SLAVE:
c02: set the parameter = 1
c03: set the parameter = from 2 to 8 (SLAVE)

NOTE:
the
fies the position of the Slave inside the cascade.
It is therefore necessary to make sure that the assigned value
has not already been assigned to another unit and, above all,
that the water heater is identified with an increasing number,
from 2 up to the number of units present (maximum 8 units).
Example of setting parameter c03 for a cascade of 4 units:
•
unit 1 (master) c03=1
•
unit 2 (slave 2) c03=2
•
unit 3 (slave 3) c03=3
•
unit 4 (slave 4) c03=4

c08: The parameter defines the rotation time expressed in days

I
to define the period of cyclic rotation of operation of the various
8

units. The cyclical rotation has the purpose of guaranteeing a
8
I
use and therefore a balanced wear in terms of operating time
8
I
of all the units. Higher values of the parameter do not affect this
8
I
function but only involve longer times to reach it: it is therefore
30

advisable not to modify this parameter.

3.9.15.1 Serial Number display "parameter U03"
By accessing the U03 menu you will be able to view the value
relating to the serial number.
The serial number display is divided into pairs of two characters
and is made up of a maximum of 8 pairs.
The display on the display is as follows:
•
the number to the right of the dot represents the number of
the pair of characters displayed (1 = first pair of characters, 2
= second pair of characters ... 8 = eighth pair of characters)
•
the two characters to the left of the dot are the serial cha-
racters relating to the selected pair.
By pressing the + and – keys it is possible to view the various
pairs of characters.
