11. CONTROL OF SEVERAL BOILERS – CASCADED SYSTEM
In an installation with several boilers it is important that the power generated by the boilers adapts at any
moment to the demand of the installation, always optimizing the generators’ efficiency.
11.1 Boilers sequence included
When there are several boilers
supplying
the same
installation, the boiler LMS
control unit is able to make a
sequence up to 16 boilers
equipped with this controller.
The boiler with device address
1 assumes the role of the
cascade master.
It
activates the required
functions and shows the
additional menus with the
parameters for use with the
cascaded system.
Components and actions
For each boiler the following components and actions are necessary:
•
Add an additional module OCI345.06/101 (consult the current pricelist) of communication bus type LPB
•
Connect the additional module to the boiler control unit, by means of the bus cable included in the OCI345
(see the photo attached).
•
Make a serie between each OCI345 of the boilers connecting (DB – LPB data bus and MB – LPB ground).
