Configuring a time dosing cycle

This function is available as an option. See section 9.5.
It is used to add one or two products to the process, either at regular intervals ("DoMode" = "Period"), or
according to the days of the week ("DoMode" = "Week"). The quantity added is proportional to the time
open (programmable) of the command unit.
