Output (Control and Retransmission) Functions
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.

The following explains an example of letting OUT terminal and RET terminal present the
V-mode characteristics of split computations.
