Why is my Omron Temperature Controller overshooting, undershooting, or hunting?
- JJorge FuentesAug 18, 2025
If your Omron Temperature Controller is showing overshooting, undershooting or hunting, it could be due to several reasons. First, if ON/OFF control is enabled, select PID control and perform autotuning. Second, if the control period is too long compared to the temperature's rise and fall speed, shorten the control period. Third, unsuitable PID constants can cause this issue; execute AT (autotuning) or manually set appropriate PID constants. Finally, an HS alarm operation fault may be the cause; use breeder resistance if leakage current is the problem and investigate errors detected by the HS alarm function.
