What does Coreco LOC mean?

On the Coreco controller (Dixell XW30/XW60/XW70), LOC is a display message meaning the keyboard is locked (it can lock automatically). It is not a fault — it prevents unintended changes to the set point and parameters.

Symptoms

  • Display shows LOC when a key is pressed
  • Set point / parameters cannot be changed

Common causes

  • Keyboard locked automatically
  • Keyboard lock enabled by the user

Diagnostic steps

  1. 01

    Unlock the keyboard

    LOC means the keypad is locked; unlock it with the keyboard-lock key sequence for the model (the display shows Pon when unlocked).
