Standard Splitter Output (STD SPLITTER)
This function can be used for heat/cool applications. It is a deadband-based splitter that divides a Split
loop's output (-100% to +100%) into two outputs CVn A1 and CVn A2, both of which are zero when the
loop output is zero (Figure 4-14). A deadband provides a range of loop output within which both split
outputs remain at zero. For overlapped outputs, use Advanced Splitter. Note: A third output CVnA3 is
displayed Online and should be ignored.

Table 4-42 describes the Standard Splitter prompts. See Table 4-2 for additional prompts.
