8. Before Performing a Control
･ This product uses nonvolatile memory to memorize settings. It retains its settings even if its power is turned OFF.
･ This product can switch the input type of the sensor. Upon using the product, please match the type of the sensor with the
sensor setting of the product.
･ This product can perform two types of control: PID and ON/OFF.
The characteristics of each control are described below. Choose the control to use based on their characteristics.
PID Control
Pros: Can achieve better control result than ON/OFF control.
Cons: Life of a relay contact point gets shorter because of the frequent ON and OFF of the output.
ON/OFF Control
Pros: Life of a relay contact point is generally longer since it turns ON if the temperature is lower than the setting value and OFF
if higher.
Cons: Less controllability than PID control.
