This PID controller has a built in timer. It is suitable for processes that require both precise temperature and time control, a very common requirement for many temperature related applications. For example, it can be used for powder coating ovens or ovens for cooking food. Heat transfer printing is another example. The timer can also be used independently from the temperature control. user can use the PID for temperature control of the espresso machine and timer for the brew pump or dosing coffee grinder.
