Troubleshooting
The Simple Astronomical Timer is only for use in single-pole circuits, i.e. it should be used in locations where it's the only switch controlling the light.
If the screen is not lighting up on your Simple Astronomical Timer, this can be caused by two wiring issues:
- The Neutral wire is is disconnected.
- The Hot and Load wires are swapped.
If this is the case, contact Deako Support.
