If the LCK/STP LED is off, it indicates that the holiday lockout feature has been activated. If no auxiliary device is connected to the LCK/STP terminal, this could be due to a remote button being incorrectly programmed, a disconnected wire from the LCK/STP terminal, or an active timebar setup in the ChronoGuard menu.
To resolve this, please follow these steps:
1. Unlocking with the Remote (if activated via a remote)
- Press the same Nova remote button that may have activated the holiday lock.
- Test each button on your remote until the LCK/STP LED on the PC board illuminates, indicating the lock has been deactivated.
2. Using a New Remote Button if the Remote cannot be detected (if activated via a remote)
If the original Nova button cannot be identified:
- Program an unused Nova remote button for the holiday lock function. Steps to add a remote for holiday lock can be found here.
- Once programmed, press this button to deactivate the holiday lock. The LCK/STP LED on the PC board should illuminates when the button is pressed.
- After deactivating, delete the button from your remotes list by navigating to:Remotes → Delete Remote → Delete Remote Button. Steps for deleting a remote button can be found here.
3. Resetting the Board (If triggered by an auxiliary device or wire removal from the LCK/STP terminal)
- Perform a factory default via the General Settings menu. Steps for factory default can be found here .
- Alternatively, deactivate the lockout by connecting a wire bridge between the LCK and COM terminals.
4. Checking ChronoGuard Settings
- Review and delete any active timebars under the ChronoGuard menu:
ChronoGuard → Delete All Time Periods and Exclusions → Yes.
5. As a last resort, before taking the board to a CENTURION branch, you can perform a Reset All.
- Perform a reset all via the General Settings menu → Reset options → Reset All - Yes..
Kindly note that this option will completely clear the memory, including all settings, remotes, and limits. Everything will need to be reprogrammed.
