Optional Modules
Extension Module & Cable Hub
NESTA PLUS boilers can control 3 heating circuits
with mixing functions, using 3 extension modules.
Each extension supply needs to be provided with
power supply and a bus connection.
Web Server Module
Through the use of this module, you can connect
to an Ethernet and get remote access to the boiler
and all the heating system via the Internet. Using
a computer or mobile devices, you can monitor
and control the installation remotely. Management
takes place via a web browser.
Cascading module
This module allows the installation of several boil-
ers in a cascade to increase the heating power in
specific applications. This cascade module en-
ables communication from one boiler to another,
and must be installed in each boiler. See
“Boilers
in a Cascade System” on page I-64.
