The ST502-QF1TA.19 controller performs the function of a temperature controller with a run-down time. The temperature control can be linked to the run-down time. It is then only active while the timer is running. A release temperature can be set to start the timer. The controller has a four-digit LED display, 6 buttons and 2 contact outputs. The various temperature setpoints and time specifications can be parameterized directly using the buttons.
