BASIC OPERATION
When the controller is set up for on/off control, the manual output is a time
proportioning signal. This gives the output infinite adjustability between 0 and
100% rather than limited to the two-state 0 and 100% values of the automatic
mode. In manual the output can be adjusted to any value needed to maintain
the process at the set-point.
When the controller is set up for manual reset, manual reset values entered
while in auto or manual take effect when the controller is switched from
manual to auto.
Manual Operation with Remote or Multiple Set-Points

enabled in the SETPTS MENU, the front face will resemble the examples
below:
