Thanks for reply. 'Program' is not an option from Menu. There are only six options when you hit Menu: Settings, Speed 1-8, Ext control, Features, Priming, Anti-freeze. None of these options has program under it. It's kind of strange, to set a scheduled start and stop time you have to select 'Speed 1-8' and then select 'Schedule'. Whoever designed this user interface had no computer ergonomic background.
