Working Principle: Set the time in advance; mechanically driven. The built-in battery provides continuous operation for 80–100 hours during power failure. This is a 24-hour timer switch with a minimum setting interval of 15 minutes. A clock indicator on the faceplate shows the start time of the programmed mode. An “I” symbol on the panel indicates the lock function.
