1 INTRODUCTION
This document describes the
i
CCS which is a commercial control
system platform that is integrated at all levels in a plant room, from
the combustion manager within the boiler to the extension module
at the final heating and DHW circuits.
It covers the description of the system and its modules, along with the
configuration, hydraulic circuits supported, interconnection wiring,
data logging and fault management.
The
i
CCS consists of:
•
Boiler combustion manager
•
System manager
•
VariCAN adapter
•
Extension module
•
System accessories
1.1 Combustion Manager
The Combustion manager is mounted in the boiler and controls
the internal safety functions associated with a heat engine. It also
provides information to the System manger on the status of the heat
engine as well as auxiliary inputs and outputs.
1.2 System Manager
The System manager is located within the boiler and provides the
controlling functions. One System manager is required per boiler, it
can support multiple Combustion managers. The System manager
also provides the User interface function.
A System manager can be configured as a Master or Slave in a
cascade of Boilers, and/or when any external module is used. E.g.
Extension module.
The Master System manager controls both its own Combustion
manager and all other Slave System managers as well as the
external modules. It can also control other Combustion managers
within the same boiler.
1.3 VariCAN Adapter
The VariCAN adapter is an optional accessory that is installed within
the boiler. It allows the Bus communication system to be extended
outside of the boiler to either other boilers in a Cascade, where each
boiler requires one, or to the Extension modules.
1.4 Extension Module
The Extension module adds additional Heating, DHW storage and
Hot Water Systems to the installation.
1.5 VariCAN Bus
The iCCS communicates using the VariCAN bus. A total of 60 devices
can be managed on a single bus, made up from a mix of Combustion
managers, System managers and Extension modules. Each of these
is counted as one device on the VariCAN bus.
It is possible to cascade up to 16 boilers on the VariCAN bus, 1
Master System manager and 19 Slave System managers.
The system can support up to 8 Extension modules.
However, the total number of devices still cannot exceed 60.
