diagnosis function, is able to identify and monitor in real time the boiler status,
check the causes and communicate all informations on the display.
Indeed, each operation will result easy and quick thanks to the display that visualize
all parameters to manage the boiler and, in case of component replacement due to
a fault, this won’t be a problem thanks to frontal access to all components.

2 EASY TO SELL
The PIGMA boiler and its features make the offer attractive for the installer for any requirement
Design & easy interaction
A new design, the materials quality and the attention to aesthetic details allow installing PIGMA in every
place, also the most sophisticated.
The control interface has been carefully designed in order to guarantee an easy of use thanks to the digital
display and to the different levels to manage different functions.
From the simple CH and DHW temperature management through two big knobs, to the other functions
through the programming buttons.

2.2 DHW COMFORT
2.2.1 DHW performances & certification
The hot water production represents the most important value for any boiler and the PIGMA has achieved
successfully the best level according to EN13203 in terms of:
• SPECIFIC RATE
• TEMPERATURE STABILITY
• NO WAITING TIME
• MINIMUM NOMINAL WATER FLOW RATE
2.2.2 New DHW modulation
The new DHW modulation of PIGMA guaranties a good control of the
DHW thanks to the two primary sensor and the new flow sensor with
turbine able to adapt the boiler output according to real need (flow
rate/T stability).
2.2.3 DHW Plate heat exchanger reheating (COMFORT function)
This function permit to maintain the temperature of the plate heat exchanger for a DHW waiting time
reduced.
One push on the comfort button and the reheating is activated.

2.4 HEATING COMFORT
2.4.1 Heating performances & certification
In line with the most severe European standard in term of energetic efficiency, PIGMA is certified ***
according to the European standard 92/42/EEC, one certificate which offer also a guaranty of saving.
This result thanks to the quality of the components and the intelligence of the boiler capable to optimize the
performances of the combustion & hydraulic group.
2.4.2 System approach
The boiler value is measured by the capability to give the right answer to the specific request independent of
the change of the external (climatic) or internal condition.

3 EASY TO INSTALL
Each elements of this boiler as been designed to give to the installer the maximum easiness and fastness in
the installation activity: hydraulic, exhaust gas flue & electrical connection.
The PIGMA, even if lighter compared with the old Chaffoteaux range, keeps exactly the same hydraulic
connections for an immediate replacement of the old previous models respecting the existing installation.
Chaffoteaux represents a reference for the market and continues to represent the best solution for the new
installation and replacement of all boilers with the biggest distance between the hydraulic connections and
the wall, 230 mm.
For the flue gas exhaust, every configuration is possible and in case of twin pipe system configuration the
installer has the possibility to connect the air inlet piping on the left- or right-hand side; furthermore the
reduction in the fixing width between the flue gas exhaust and the hydraulic connections (only 830 mm)
mean that the boiler can be installed easily and quickly, even if in case of replacement with rear pipes
installation.
Also for the electrical connections, has been created an installer zone, in the Frontal Panel rear side, for an
easy access to the PCB box where all the connections with the external devices can be easily done.
A wide range of temperature control accessories can be installed, wired (with wires) and wireless (without
wires), in particular the last one permits a complete installation quickly and in a non-invasive way.
Also in terms of function PIGMA has been designed to help the installers in their activity, the Automatic Air
purge” for example facilitates the elimination of any air bubbles present in the heating circuit, optimizing the
activity, reducing the time for the completion of the installation and the noise for the end user.
Another important value of this boiler is its capability to work perfectly integrated with the most complex
domestic system for heating and DHW production.
In the first case, a complete of Multizones Modules:
- up to tree zones monotemperatures
- multizones temperatures up to tree zones (HT+2 LT zones)
Allows a total personalization in the installation
For the DHW production, the boiler is set up for use in a system which uses solar panels in series and in
parallel.
Where forced circulation is used, it can control the system directly with the boiler interface with a small clip in
out to put in the electrical box, already predisposed, and without a specific external device not linked to the
boiler.
