A timed programme means a cycle you can set to last a certain amount of time. For example, some dryers have a ‘Quick dry programme’.
For timed programmes, there might be a dial where you set the cycle time. Alternatively there might be set cycle times you can choose from on the tumble dryer’s control panel.
Some dryers also have a delay setting. This lets you set a time in the future when you want the programme to start. The symbol for this is often a clock or stopwatch.
