LC displayed; unit does not start; controls may be locked

Note: LC on many Olimpia Splendid units is not a fault but a lock indication.

• Unlock via remote: Press and hold the "+" and "-" temperature buttons together for several seconds (or refer to your model's manual) to toggle the lock.
• Unlock via panel: On some models, press and hold the "MODE" or "LOCK" icon button for 3–5 seconds.
• Power reset: If the lock does not clear, unplug the unit for 5 minutes and retry the unlock sequence.
• Stuck buttons: If certain keys are physically stuck, gently clean around them. If the keypad is damaged, the control panel may need replacement.
