Gain #4, Rate #4, Reset #4, Cycle #4 Time
TWO SETS PV AUTOMATIC SWITCHOVER—
When the process variable is GREATER than the
value set at prompt SW VALUE (Switchover Value),
the controller will use Gain #3, Rate #3, Reset #3,
and Cycle #3 Time. The active PID SET can be read
in the lower display.
When the process variable is LESS than the value
set at prompt SW VALUE, the controller will use
