3.8 CASCADE FUNCTIONALITY
The term cascade is intended to indicate a group of water heaters that work
together, within which only one Master and several slaves are identified. The
Master has the task of managing the operation of the units connected to it.
The electronics of the unit, in fact, allows the unit to be configured both as
Master and as Slave. While managing the cascade, the MASTER can manage three
different levels of operation, depending on the user’s request: 1. minimum
level of functioning 2. medium level of functioning 3. maximum operating level
Under normal operating conditions, the MASTER has full control of all Slaves.
It is indeed capable of · manage the operating status of each Slave · modify
the setpoint of all the Slaves · modify some parameters of all the Slaves
according to its
values · if the solar function is active, inform the Slaves of the tem-
perature read by the PT1000 probe of the solar panel · read the status (e.g.
alarms, water temperature, …) of each
SLAVE · keep the Slave clock updated
NOTE: only from the master display will it be possible to change the system
status, such as setpoint, operating mode, time band programming. From the
display of the SLAVE, on the other hand, it will only be possible to view its
status.
3.9 HOW TO ACCESS THE USER AND INSTALLER MENU
In addition to the possibility of changing the set-point, it is possible from
the display make some adjustments. Some parameters can be changed by the user,
others only by the installer of the unit. All parameters are divided into
various submenus, according to their functionality.

3.9.5 ENERGY MONITORING
The Energy Monitoring function allows, through proprietary algorithms, an estimate of the values of thermal NOTA energy produced and of the relative share of the renewable part and of the electrical energy absorbed. The algorithms have been defined through laboratory tests with the units operating with standard factory parameter configuration and in standard operating conditions as defined by the EN 16147 standard. Therefore, the values indicated by the Energy Monitoring function are purely indicative and are intended to make the end user more aware of consumption based on different uses (operating mode and setpoint) and have no purpose of accounting for the thermal energy produced or of the electricity consumed. To view the electricity consumption, the thermal energy produced and the renewable energy, access the En menu by pressing the “SET” key and scrolling with the “+” and “-” keys, the values “E_A”, “E_t” will appear and “E_r”.

3.9.9.1 EVU functionality (see also “9.10.1 Remote connections” on page 56)
This function is indispensable if a subsidized electricity tariff is
subscribed for heat pumps. The aim is to facilitate operation when the cost of
electricity is low, but still having to comply with the rules of the energy
supplier who will be able to decide when to interrupt the supply. To meet this
requirement, the water heater electronics are fitted with a digital input
which, when opened, allows the unit to be switched off and thus reduce the
load on the electricity grid.
NOTE: When enabled and active, this feature takes priority over the PV feature. To set the parameters, access the phv menu, by pressing the

With the photovoltaic function active (P01 set to 1), the heat pump and the electrical heater will be activated simultaneously until the set-point set for this mode is reached. The setpoint is defined by the PV offset parameter (parameter P02) which defines by how much to increase the standard setpoint with active photovoltaic. For example, if the offset is equal to 20°C and the setpoint = 50°C the setpoint will be 50+20=70°C. In any case, by default the maximum setpoint is 75°C, therefore if offset=30°C and

3.9.10 SG MENU – Smart Grid functionality (see also “9.10.1 Remote
connections” on page 56)
The water heater is designed to be integrated with an intelligent electricity
network (SMART GRID), managing it efficiently. The electronics of the unit, in
fact, provides two digital inputs for managing this function and, depending on
their condition, decides how the water heater must work, distinguishing
between four possible operating states: · Operating state 1: in this operating
state the unit is put
into STAND-BY mode and its duration can be a maximum of 2 consecutive hours
for a maximum of three times a day. If these conditions are not respected, the
electronics will change the operating state bringing it to operating state 2.
· Operating state 2: in this state, to obtain maximum efficiency, the unit
will work in ECO mode. · Operating State 3: You enter this state when you have
the opportunity to take advantage of some excess energy. In this state, in
fact, the unit is made to work in BOOSTER mode by raising the setpoint by a
pre-set value (offset) up to a maximum of 75 °C. In this mode, the water
heater will reach a DHW storage temperature equal to the previously set
setpoint value, plus an offset (defined by parameter G02). For example, if the
offset is equal to 20°C and the setpoint = 50°C the setpoint will be
50+20=70°C. In any case, by default the maximum setpoint is 75°C, therefore if
offset=30°C and setpoint=50°C the setpoint will not be 50+30=80 but 75°C. ·
Operating state 4: when there is a lot of excess energy, the electronics will
use the moment to make the water heater work in BOOSTER mode with a fixed
setpoint of 75°C (max setpoint).
To set the parameters it is necessary to access the SG menu, by pressing the “SET” key the values “G01” and “G02” will appear.

fourteenth day.
ATTENTION: the 14-day waiting time cycle may not even be respected because if,
during normal operation, the temperature of the water inside the tank already
reaches 62°C for a minimum time of 30 minutes, the waiting time is reset.
NOTE: If after its activation, the ANTI-LEGIONELLA function fails to satisfy
the temperature conditions defined by parameter h02 for a minimum time defined
by parameter h06, and after the time defined by parameter h05, the function
will be suspended and the unit will to work under normal conditions. In the

From this menu it is possible to enable and disable the ANTILEGIONELLA
function and set the parameters for its correct functioning. To limit the risk
of legionella spreading, the water heater is in fact equipped with a function,
called ANTI-LEGIONELLA, which, if enabled, allows automatic disinfection
cycles to be carried out, bringing the water temperature inside the tank
through a cycle of water heating at 62°C (changeable default value),
activating the heat pump and the electrical heater and keeping them for 30
minutes (changeable default value), ensuring the elimination of any bacteria
present. This feature is normally set up to activate autonomously every
Parameters: h01: from this parameter it is possible to enable or disable the
ANTI-LEGIONELLA function: h02: when the function is enabled and active, this

c08: The parameter defines the rotation time expressed in days to define the period of cyclic rotation of operation of the various units. The cyclical rotation has the purpose of guaranteeing a use and therefore a balanced wear in terms of operating time of all the units. Higher values of the parameter do not affect this function but only involve longer times to reach it: it is therefore advisable not to modify this parameter.

PROHIBITION
The device cannot operate in rooms classified as environments with an explosive atmosphere or at risk of fire.
ATTENTION
The general operation of the device is guaranteed by observing the environmental conditions indicated.
ATTENTION
The equipment has not been designed to be installed outdoors but to be used in a “closed” environment not exposed to the elements with an ambient temperature between +4 °C / +43 °C. To avoid the risk of freezing, if the appliance is installed in an area subject to temperatures lower than those indicated, when it is not electrically powered, the water present in the tank must be emptied. Empty it as described in the appropriate chapter.
For the correct operation of the device it is necessary that its positioning meets the following requirements: · away from heat sources, · away from direct sunlight, · away from air conditioning systems, · in a dust-free environment. The environmental conditions for operation are shown in the table below.
Ambient external air temperature (min. / max.)
-7 °C / +43 °C
9.3.2 Physical characteristics of water The Langelier index of the water,
measured at the operating temperature, must be between 0 and +0.4 The device
must not operate with water hardness of less than 12°F. Conversely, if the
water hardness is very high (over 25°F), use a suitably calibrated and
monitored water softener, because the residual hardness must not drop below
15°F.
OBLIGATION
NB: In the design and construction phase of the plants, the applicable local regulations and provisions must be complied with.
9.4 PREPARATION OF THE INSTALLATION SITE
Proper operation affects the life of the device and its components, but above
all it affects the efficiency of the system. We recommend that you carefully
follow the instructions below; our Technical Assistance Office is available
for any clarifications on the matter.
OBLIGATION
In the planning and construction phases of the systems, the standards and regulations in force locally must be complied with. The equipment must be installed and operated by a qualified technician in accordance with local health and safety legislation and regulations. Incorrect installation can cause damage to property and injury to people and animals; the manufacturer declines all responsibility for the consequences. The air inlet and outlet of the appliance must be ducted as indicated in the paragraph 9.6 on page 44.
The product must be installed in a suitable place, i.e. to allow normal use and adjustment operations as well as routine and extraordinary maintenance. The place where it will be operated must, therefore, be prepared according to the values shown in fig. 49 and fig. 50.

Install each air duct making sure that:
· It does not weigh down on the equipment.
· It allows maintenance operations.
· It is adequately protected to prevent the accidental intrusion
of materials inside the equipment.
· The connection to the outside must be done with suitable,
non-flammable piping.
· The total equivalent length of the extraction pipes plus the
delivery, including grilles, must not exceed 12 m.
The table gives the characteristic data of commercial ducting
components with reference to nominal air flows and diameters

· While operating, the heat pump tends to lower the tempera-
ture of the room if the air is not ducted outside.
· A suitable protection grille must be fitted during installation
near the external air exhaust pipe, to prevent foreign bodies
from getting inside the device. To ensure maximum product
performance, the grille must be selected from those with low
pressure loss.
· To prevent the formation of condensate: isolate the air ex-
haust pipes and the ducted air cover attachments with a va-
pour proof thermal coating of a suitable thickness.
· If necessary, install mufflers to prevent noise due to the air
flow. Fit the pipes, wall entries and connectors to the heat
pump systems with vibration damping.
ATTENTION
Operating an open-chamber hearth (e.g. open fireplace) and the heat pump at the same time will cause a dangerous drop in pressure in the room.
The negative pressure can cause the return of exhaust gases into the room. ·
Do not operate the heat pump together with
an open fireplace. · Only operate fireplaces with airtight cham-
bers (approved) with separate combustion air ducting. · Keep the doors of
boiler rooms sealed and closed so that the combustion air is not drawn from
living areas.

Nota:
Over 4 units (max 8), consider two separate ducts referring to
the diameters in the table relating to the number of units con-
nected in parallel.
Example with 7 units:
· No. of units connected in parallel on the first duct:
4 ØD = 300 mm
· No. of units connected in parallel on the second duct:
3 ØD = 250 mm
To avoid air recirculation it is mandatory to install a non-return
valve (part.1 fig. 56 and fig. 57) on the air expulsion duct of each
unit.
9.6.3 Special installation
One of the peculiarities of the heat pump heating systems is that these units
considerably lower the air temperature, generally expelled to the outside of
the house. As well as being colder than the ambient air, the expelled air is
also completely dehumidified, therefore the air flow can be returned inside
for the summer cooling of specific rooms or areas. Installation provides for
splitting of the extraction pipe, which is fitted with two dampers (“A” and
“B”) for directing the air flow to the outside (fig. 59) or the inside of the
house (fig. 58).
