Why Does E5[]N Basic-Type Digital Temperature Controllers Overshoot Or Undershoot?

  • The proportional band is too narrow and the P constant is too small.
  • The integral time is too short and the I constant is too small.
  • The derivative time is too long and the D constant is too large.
  • It is in ON/OFF control mode.
  • The control cycle is too long for a control system with fast thermal response.
    The overlap band setting is mistakenly set for a dead band setting in heating and cooling control.
Applicable models: E5CN, E5GN, E5EN, and E5AN
