The Switch Delay is basically a delay added to the manual switches . This delay is required so that whenever the power goes and comes back within milliseconds , the device should not turn on the load. To prevent this, a delay check if the manual switch is ON for the specified delay before turning ON/ OFF the load
16A also has a manual switch , so switch delay is required. with v7.0 firmware you can change switch delay
Possible solution
- Keep the manual switch in OFF state and see if the problem goes away.
- If the problem goes away , increase switch delay.
