Default I/O connection diagram
The default connection of the control signals depends on the application macro in
use, which is selected with parameter
9902 APPLIC MACRO .
The default macro is the HVAC Default. It provides a general purpose I/O
configuration with three constant speeds. Parameter values are the default values
given in section
Parameters in the short parameter view on page 144 . For information
on other macros, see section Application macros on page 79 .
The default I/O connections for the ABB standard macro are given in the figure below.
