Operating mode Push to start the blinking action as described above. At release, the timer will start. When time Blinking circuit elapses, the load is turned off. A push during on-time restarts the timer. with timer Applications : warning lights, buzzers, … As long as the button is closed, the system will activate the output in a random manner (9 min- utes to 2.5h between every transition).
Operating mode & Learning mode 21. Learning mode The learning mode allows you to store two different delays, each from 2s up to 12 days. The delays are called delay1 and delay2. Originally, delay1 has been factory set to 3 minutes, while delay2 has been set to 30 minutes. All timer modes use delay1, unless the mode uses both delays.
