• How do I access the parameter setup menu on my LAE controller?

  On many LAE Electronic models, such as the CD5 series, you can access the configuration menu by entering the INFO menu and inputting the default password '123' when prompted.

• How do I mute the alarm buzzer on the controller?

  If the controller sounds an alarm due to high/low temperature or another fault, simply press any button on the display face to mute the buzzer.

• What do the error codes E1, E2, or E3 mean during autotuning?

  E1 indicates a timeout error where the temperature did not reach the proportional band. E2 indicates the process took too long overall. E3 indicates a temperature overrange error, often requiring a check of the probe or setpoint adjustment.

• How can I lock or unlock the keypad?

  To prevent unauthorized changes, navigate to the INFO menu and set the parameter LOC to YES. To unlock the keypad, change this setting back to NO.
