There are several methods by which the TMC-424 can be operated manually.
A separate Function Dial position is provided for Manual Stations operation
and Manual Programs operation.
Manual Operations by Station

method, called "True Manual" enables an individual station to be simply turned
on without a specified run time duration.
The second method called “Timed Manual” enables selected stations to be run
with a selected (temporary) run time duration.
