Special note for millivolt option:
If the millivolt option is fitted, then the command output is used as the excitation source for the
transducer. As such the SP: will change to EXP: to indicate that the user is controlling the excitation
output.

Main Screen (Setpoint Valve Control)
Rather than commanding the setpoint to a specific value, the setpoint mode can be
changed to Open or Closed which overrides any previously set value. Again the
main screen shows everything as normal, but with the addition of the OPEN or
CLOSE identifier if this mode has been set. By putting the device into override mode
it is possible to force the setpoint to be Open or Closed. This is done by pressing
the override switch then the appropriate mode switch. Either mode can be cancelled
by switching back to Auto mode (by effectively pressing the override switch twice).
