Cascade Configuration
Once the VariCAN adapters have been
installed and connected into each boiler
in the cascade then the cascade can be
configured.
Power up each boiler in the cascade then
return to the Cascade Master boiler to start
the configuration. The following screens will
be displayed on each boiler at power up:

Once the Master boiler has the date and
time set then all slave boilers will adopt
these settings.
Once ‘Done’ is selected, the following screen
will appear:
Set boiler number
Boiler 01 Master
Boiler 02
Done
This is an example where there are two
boilers in the Cascade, each Slave boiler will
be listed from Boiler 02 onwards, Boiler 01 is
always the Master, and the configuration of
Slave boilers will be different to the Master
but will follow the identical procedure.
The Boilers numbers in the case of only 2
boilers can appear in any order, this is in
relation to how they are discovered during the
Bus Scanning process, and the Slave boiler is
also pre-allocated as boiler 2. When a Boiler
is highlighted in the menu, the corresponding
TTL-i5 VariCAN adapter LED will illuminate, in
the case of a Slave boiler the System Manager
Display will also change to inverse video to
allow identification, selection and labelling. For
any Slave boilers where there is more than 2
boilers in the cascade, the display will show:
Set boiler number
Boiler 01 Master
Boiler ##
Boiler ##
If any Slave boilers are not listed, check that
they are connected correctly to the bus and
that they have their power switched on.
Each Slave boiler can be selected and a
number allocated, usually corresponding to
their physical location in the cascade:
Set boiler number
Boiler 01 Master
Boiler 03
Boiler 02
In the case above, the second Slave boiler
highlighted was identified as Boiler 03 in the
cascade, and the third Slave as Boiler 02,
adjacent to the Master boiler.
Once you are happy with the selection of
the Slave boiler numbers, select ‘Done’. The
following screen will then appear:
The Master boiler is now scanning the
installation to locate all of the connected
boiler Heating Circuits.
