This usually means that your neutral is not correctly wired to the switch. Unlike a single-pole switch, most digital timers require a neutral. You should have four connections on the timer:
- hot lead (connect to incoming hot lead from the circuit breaker)
- load lead (connect to outgoing hot lead to the light fixture)
- neutral lead (connect to the neutral lead from the main panel and to the neutral lead from the light fixture)
- ground lead (connect to the ground conductor from the main panel and to the light fixture).
It is possible that your original switch was on a switch loop and there is not a neutral conductor in the device box; if this is the case, you will need to pull a neutral conductor into the device box to make the digital timer work properly.
