Using 'If Control' versus 'If Status' in Programs

The reason to use control condition is that a control will trigger a program evaluation upon
EACH receipt of the anticipated command. Unlike control, a "status" condition will trigger an
evaluation only after a CHANGE in status. If a device status is off, and you turn it off again, the
status has not changed and no program evaluation will take place.
