One of the auxiliary commands has to be set to AUTO / ON-OFF to operate remotely (see §16.3).
The actuator is on positioner control when this setting has been completed. The auxiliary command
must be switched for On-Off commands. This auxiliary command is used for selecting positioner or
on-off control remotely.
See §26 for further details, particularly regarding deadband settings.
