This usually means one of 3 things:
- Vacation model is enabled. You can verify if it’s enabled by using the Enhanced DTH to read the settings in the Classic app (and change it)
- The lock isn’t oriented properly, it may need to re calibrated. Check the manual to see how to recalibrate the lock
- The motor is blocked or defective (check door jamb and mounting)
The green flash means the code was accepted and valid. The red mean the next action (unlocking) was blocked, either due to a settings or a physical constraint of a mechanical issue.
