You can change and force values using a graphic or the Properties pane. Using the Watch pane, you can dynamically monitor a value.
When you force a value, all input from the system is overridden. For example, a schedule is set to start a fan at 09:00 but you want it to start at 08:00. In this case, you can force the fan to start at 08:00.
