1GENERAL INFORMATION
1.1 GENERAL WARNINGS
ATTENTION!
e heat unit must be installed so as to avoid, under the envisioned operating conditions, the liquid contained in it from
freezing and avoid exposing the command and control parts to temperatures below -15°C and over +40°C.
e heat unit must be protected from climatic/environmental variations by:
- insulating the hydraulic and condensation exhaust pipes
- adopting specic anti-freeze products in the hydraulic system.
e instruction handbook is an integral and essential part of the product
and must be kept safe by the user.
Read the warnings contained in the handbook carefully, as they provide
important instructions regarding installation, user and maintenance
safety.
Keep the handbook safe for future consultation.
e appliance must be installed and maintained in accordance with
regulations in force, pursuant to the instructions of the manufacturer,
the state of the art and by authorised and qualied personnel, in ac-
cordance with the law.
Domestic hot water production systems MUST be built entirely with
compliant materials.
Professionally qualied personnel means sta with specic technical
skills in the sector of heating system parts for civil use, hot water pro-
duction for domestic use and maintenance. is personnel must have
the authorisations required by legislation in force.
Incorrect installation or poor maintenance can cause injury to persons
and animals and damage to objects, for which the manufacturer is not
liable.
Before carrying out any cleaning or maintenance operations, cut the
appliance o from the power mains by acting on the switch on the
system and/or using the cut-o devices.
Do not obstruct the intake/exhaust pipe terminals.
In case of breakdown and/or poor operation of the appliance, switch
it o, and do not attempt in any way to repair it or intervene directly.
Only contact an authorised company that has been authorised in
accordance with the law.
Any repairs to the products must be carried out by an authorised
company only, using original spare parts only. Failure to observe the
above can jeopardise the safety of the appliance and will void the
warranty.
e guarantee the eciency of the appliance and its correct operation
it is essential for authorised company to carry out annual maintenance.
If the appliance is put out of use for downtime, any part that is
susceptible to posing a potential source of danger must be made safe.
Before re-commissioning an appliance that has been put out of use,
proceed to washing the domestic hot water production system, making
water ow through it for the amount of time required to change the
water completely.
If the appliance is sold or transferred to another owner or if the owner
moves, leaving the appliance behind, always ensure the handbook
accompanies the appliance so that it may be consulted by the new
owner and/or installer.
All appliances with optionals or kits (including electric) must only use
original spare parts.
e appliance must only be employed for its expressly foreseen use.
Any other use must be considered improper and therefore dangerous.

ATTENTION!
Instructions for appliances running on propane gas
Make sure that the gas tank has been deaerated prior to installing the appliance.
For a thorough deaeration of the tank contact the liquid gas supplier and in any case authorised company, in accordance with the law.
Ignition problems can arise if the tank is not thoroughly deaerated.
In this case contact the liquid gas tank supplier.
Smell of gas
In case of the smell of gas observe the following safety instructions:
- do not use electric switches
- do not smoke
- do not use the telephone
- shut o the gas cut-o valve

General information
1.7 WATER TREATMENT
Treating the supply water allows you to prevent
problems and maintain the functionality and
eciency of the generator over time.
e ideal pH value of the water in the central heating
system must be:
VALUE MIN MAX
PH 6,5 8
HARDNESS (°fr) 9 15
To minimise corrosion, it is essential to use a corrosion
inhibitor. In order for it to work eciently, the metal
surfaces must be clean.
ATTENTION!
Any damage caused to the boiler, due to the formation
of build-up or corrosive water, will not be covered by
the warranty.
ATTENTION!
e models only equipped with central heating are
NOT suitable for hot water production for human
consumption (M.D. 174/2004).
1.8 BOILER FROST PROTECTION
Activated by default
is protection only cuts in when the electric and gas supply are present.
If the electric or gas supply are disconnected and 11 (SM) detects a
temperature of between 2 and 5°C when the supply is restored, the
appliance responds as indicated in the table below, in pos.2.
Antifreeze products with an inhibitor for central
heating systems (specic for multimetal) can be used
to ensure ecient protection of the central heating
against freezing.
Do not use antifreeze products for car engines since
these can damage the water gaskets.

- Operation during heating: determining the instantaneous power
through a control microprocessor, with preset comparison parameters
between requested temperature (or calculated by the outdoor
thermoregulation) and global ow temperature.
- Logic of operation:
- Possibility of controlling the power of the single heating elements
for calibration and/or assistance with reserved access code.
- Domestic hot water production using a priority NTC probe, for
control by a storage tank loading pump or diverter valve, is done
with an SHC module that is supplied with the boiler.
- Possibility of controlling the power of the single heating elements.
- Heat request control: temperature setpoint and modulation level.
- Monitoring the state of operation and temperatures.
- Alarm notication.
- Parameter setting.
- Control relay to switch on a pump at a xed speed.
- Analogue 0÷10V output to control a modulating pump.
- Emergency operation: this allows you to avoid the system from
stopping due to an interruption in communication with the adjusting
system or possible remote management of the control unit:

- Alarm management.
-Alarm reset input.
-Alarm notication Relay.
- Condensation collection tray with stainless steel exhaust trap.
- Easily removable integral panelling comprised of oven-painted steel
panels suitable for outdoor installation.
- Condensation collection tray with stainless steel exhaust trap and ue
chamber.
- Incorporated deaerator.
e request for heat can be generated by the HSCP thermoregulation/
manager or alternatively by the BCM (Boiler controller).
The management logic envisions simultaneous operation of the
maximum number of heat elements, so as to always obtain the
maximum eciency. Since it guarantees the maximum exchange area
based on the delivered power. e elements are made to operate so as
to equally divide the operating time.
e hot water that is produced is pushed by the pump located on the
return of the primary ring to the ow of the hydraulic separator. From
here a second pump (system - see suggested diagrams) will distribute to
the various utilities. From the system, return the cooled water is taken
in by the pump on the return, through the hydraulic separator, to start
the cycle towards the generator again.
