10.15SettingSplitComputationOutputFunction
Description
Split computation output is useful for the case where multiple (up to 3) operating
units for switching, for example, hot and cool water are linked for control. There are
two
characteristicsof
splitcomputations:V-modecharacteristicsandParallel-mode
characteristics. The current output range can be changed.
