DIVA
DIVA is the new Ferroli proposal
for traditional wall hung boilers
with double exchanger
Its solid construction has been conceived for smart
operation in different climates and working conditions.
It has been manufactured in Ferroli’s ultra-modern facilities
in northern Italy, whose quality management complies
with UNI EN ISO 9001:2008 standards.
> MAIN FEATURES
> Traditional compact wall hung boiler for central heating
and domestic hot water
> Monothermic CH copper exchanger plus DHW stainless
steel plates exchanger fed by 230 V diverting valve
> Complete and intuitive control board, with autodiagnostic
function featuring backlit display and setting buttons
> Can be connected to modulating remote control, as
optional
>H
igh efficiency, 3 stars according to EN 92/42 (forced
flue, model F)
> Modulating operation both in heating and domestic hot
water mode, with adjustable temperature increase slope
> Hydraulic bypass as a standard
> ECO/COMFORT mode for a fast production of domestic
hot water
> Antifrost function, if gas and power supplied
>R
eady for connection to solar systems: integrated
management of combined DHW production through
boiler and solar system
>
Compact dimensions: same width and height of a
bithermic wall hung boiler
> IPX5D protection rating
> Condensing trap for air pressure switch
> RANGE
DIVA features 8 models for central
heating and instantaneous domestic
hot water production:

> MAXIMISING COMFORT AND SAVINGS
ROMEO REMOTE CONTROL
DIVA can be used with a wide range of remote controls and timers for managing the operation of the appliance. The ROMEO
remote control series features four models, allowing programming of weekly or daily comfort conditions, and the possibility
to choose wired or wireless connection.
ROMEO adopts Opentherm® communication protocol.

Setting of central heating and DHW temperature
Monitoring of boiler operating status
Displaying of temperature inside and outside the home
Boiler restart in the event of temporary shutdown
Planning of the daily or weekly room comfort conditions
Boiler’s switch on / off using a phone dialer (optional)
The modulating function available on ROMEO allows
boiler output to be modulated progressively as it
approaches the set room temperature. This improves
comfort by eliminating peaks in heat output, and
consequently ensures energy savings.

DIVA
> SOLAR CIRCUIT INTEGRATION
DIVA boasts an electronic that simplifies the integration with thermal solar sytems, both natural and forced circulation.
The microprocessor monitors water temperature coming from solar circuit through the DHW sensor and ignites the burner only in
case it is necessary. In such a case the boiler releases only the necessary heat to DHW which had already pre-heated by collectors,
in order to reach the setpoint required by the user, allowing at the same time considerable savings even during cooler seasons.
FUNCTION
M
> FUNCTIONS
> ANTIFROST
Also in standby-mode, in case the temperature in the boiler drops to 5°C (temperature detected by CH or DHW sensor), the
burner is automatically ignited at the minimum output and pump is also switched on. Thereby the appliance is protected against
damages caused by frost. This function is active when the boiler is gas and power supplied.
> ANTI-SEIZE FUNCTION
Pump is automatically switched on approximately for 5 seconds, after 24 hours of inactivity.
This protection schedule is applied also to diverting valve.
Such precaution avoids block of the mentioned devices in case of long inactivity.
> POST-CIRCULATION
This function permits to recover all heat stocked for thermal intertia in the central heating exchanger and transfer it to the
heating system, and as a consequence to the rooms. It is a timed function (with customisable span) and is active after burner
switches off in heating mode.
> OPENTHERM
The Opentherm communication protocol adopted in DIVA control board. Besides aforementioned possible connection with
modulating remote control Romeo, Opentherm allows integration of other system ancillaries, such for example, FZ4 zoning
electronic controller or DADO ZONE zoning manifold. Opentherm, as a digital protocol, permits to the mentioned accessories a
complete integration with the boiler, with full control of functions and information from the boiler and likewise from its satellite.
