Benefits of Italtherm condensing boiler
Italtherm solution to
maximise comfort and energy saving
ITALTHERM’S NEW CONDENSING BOILERS, designed in compliance with the future ERP
REGULATION, ARE THE IDEAL SOLUTION for anyone requiring A HIGH-EFFICIENCY CENTRAL
HEATING SYSTEM, WITH THE POSSIBILITY OF DELIVERING LARGE AMOUNTS OF DOMESTIC HOT WATER.
STRONG POINTS:
1
New combustion unit with 1:10 modulation
Gas savings of up to 40%.
The stainless steel condensing exchanger allows to recover the latent heat existing in the flue, considerably
increasing the energy efficiency; the innovative mixer provides a wide modulation range, up to 1:10.

ACQUA STEP (K model) and SPA (KR model) functions
For maximum DHW comfort
The Acqua Step function can be used to pre-heat the water in the maxi heat exchanger so that hot water is
always available. It can be programmed on a daily or weekly basis, with three different temperature settings.
The SPA function heats the tank to the maximum temperature for 1 hour, to deliver unrivalled DHW comfort.

Control panel
The control panel, featuring simple, intuitive commands, is used to control all the main boiler and system
functions, including the management of solar panels if present and/or management of mixed low and
high temperature systems.

Hydraulic fitting kit
This contains the quick hydraulic fittings for connecting the
boiler to the system. It comprises: 1 gas cock compliant
with legal requirements; 1 water cock; 5 pipes (6 for the Kr
model) for the gas, DHW and CH system hydraulic couplings;
appropriate fittings. All components, on the boiler side, are
push-fit couplings and are complete with hexagonal swivel
collars (swivel nuts) and the corresponding seals.
Re-usable template (in galvanised sheet metal)
This allows the installer to position the wall-hung hydraulic
fittings in exactly the right place

Kit for high + low temperature systems
This kit allows an Italtherm condensing boiler to manage a
low and high temperature CH system. When the request is
from low temperature areas only, the condensing boiler runs in
low temperature mode. When there are mixed requests from
both circuits, the boiler runs in high temperature mode and the
flow to the low temperature system is managed by the kit, by
mixing the return low temperature circuit flow with part of the
high temperature circuit flow
401100001
Remote control with climate regulator
The remote control: optimises boiler operation, interfacing
with the relevant electronics. It includes a comprehensive
weekly climatic regulator, easy to set-up and user-friendly.
It replicates all the boiler controls and provides Technicians
with diagnostic information and additional functions. Easy to
install, it replaces the Room Thermostat. It is powered by the
boiler at very low voltage, therefore no batteries are required.
401080001
Weekly scheduling digital chronothermostat
Weekly programming with 3 temperature levels. Available in
3 versions:
• Wired connection version code 401080002
it is connected to the boiler Room Thermostat line.
• GSM version code 401080004
Turn heating on and off with a phone ring! Also send an
SMS to remotely manage heating and receive an SMS in
case of fault.
• RF version code 401080005
No cables or troughs are required to connect it to the
boiler. The supply includes the radio receiver for the boiler.
401080002

The Kit allows to manage the heating of the main zone
controlled by the remote control and of other additional
secondary zones, through room thermostats and zone
solenoid valves.
401110001
Outdoor temperature sensor
This kit lets the heating system run in “flow temperature”
mode; that means the delivery temperature will vary
automatically according to the outside temperature
(measured by the temperature sensor) and to the “coefficient
of dispersion” of the building.
