Place the ON tripper at the desired hour on the dial. One tripper notch often equals 15 minutes. To program an OFF time: Place the OFF tripper at the desired hour, ensuring it follows the ON tripper in the direction of rotation.
If your model features a physical rotating dial surrounded by tiny plastic pins or segments, it is an analog variant. 1. Setting the Current Time
Verify that Terminal 3 has a live line bridge connected to it. The timer acts as a dry contact switch, meaning it does not supply voltage natively to Terminals 4 and 5 unless it is bridged from a power source.
