manifolded Infinity units.
Refer to the 'What to use where'
table to determine manifolding
components required.
Description
Infinity units can be manifolded
together (up to 25) by connecting
them together in parallel to enable
a greater hot water flow rate than is
possible with a single unit.
A manifold electronic control
system links each Infinity unit in the
system and will turn on each unit as
required. The system is designed to
ensure gas is not wasted and that an
endless supply of hot water is always
available.
How it works
A master (located internally or
externally) and sub-communication
PCB is installed in the first unit and
other subsequent units have only the
sub-communication PCB (slave cable)
installed. The master communication
PCB receives information about
flow rates from the PCB of each
unit and balances the load on each
unit. Random selection of the units
required to supply the flow demand
means that all units share the
workload evenly.
All information is transmitted via
communication cables to the slave
units. The master control also has an
inbuilt fault detection system and will
allocate a replacement unit should
one fail.
Suitability
Suitable for all Rinnai Infinity VT, HD,
and EF units.
