Temperature Controllers: ON/OFF Control

FAQ No. FAQ00542

Primary Contents


How can ON/OFF control be used to maintain the temperature at 30 degree C?


Change the forward/reverse operation setting to forward operation. When the set point is set (i.e., 30°C), the output will be turned ON when the temperature rises above the set point, and OFF when it falls below the set point.

The output will turn ON when the temperature rises above the set point again.
(The point at which the output turns ON depends on the hysteresis.)
