Note: This drawing illustrates
every terminal being used.
There are NO applications that
will be wired exactly like this.
Certain applications will use
either floating action actuators
or variable speed injection
pump mixing, not both. Also,
not all applications will use a
0-10 V (dc) modulating boiler,
therefore, it is not expected
that every terminal be wired.
Wire the control based on the
particular application.
