Summary:
The
below
illustration
shows
the
use
of
a
Optidrive
HVAC
units
as
the
controllers
in
a
variable
speed
pump
staging
system.
All
pumps
in
this
configuration
are
controlled
the
Optidrive
HVAC
units
in
variable
speed
mode
with
co
‐
ordination
and
communication
carried
out
over
the
built
in
RS485
communications
link
as
shown
below.
Drives
can
be
connected
using
the
RJ45
data
cables
and
the
RS485
Data
Cable
Splitter
as
shown
above
up
to
a
maximum
of
5
drives.

Each
motor
/
pump
in
this
configuration
is
controlled
by
a
dedicated
HVAC
drive
(one
drive
per
pump).
All
drives
run
in
variable
speed
mode
with
the
speed
reference
passed
across
the
communications
network.
One
drive
in
the
system
is
denoted
the
‘Network
Master’.
The
Network
Master
has
the
Feedback
sensor
input
connected
to
it
along
with
the
input
set
‐
point
control,
and
uses
its
PID
function
to
generate
the
operating
speed
for
the
system.
The
‘Network
Master’
provides
an
enable
status
and
speed
reference
to
the
other
drives
on
the
network.
Operational
Overview:
The
pump
staging
with
multiple

function
is
enabled
by
setting

P8
‐
14=2
(Pump

on
the
network
master
drive
only
.
All
drives
other
than
the
network

drive
must
be
set
to
communications
