1) If you go to demo.opensprinkler.com, click the lower right icon (or press key ‘m’) to bring out the menu, and go to Edit Programs, you can see the first program has a station set to run for 45 seconds.
2) On the homepage, click on the ‘Settings’ icon next to each station name, that will bring up the station attributes dialog. Uncheck ‘sequential’, that will set the station in parallel (non-sequential) mode.
