through a remote dry contact connected to optional digital input
terminals, as follows:
Run —contact closure places Program in RUN state, OR
Hold —contact closure places Program in HOLD state
Rerun —contact closure allows the Setpoint Programmer to be reset
to the initial segment of its current cycle, unit stays in previous mode.
Opening the contact will cause the Controller to revert to its original
state.
To Begin — Contact closure resets SP Program back to the beginning
of the first segment in the program and places the program in the
HOLD mode. Program cycle number is not affected. Reopening
switch has no effect.
Opening the contact will cause the Controller to revert to its original
state.
