The instructions do not mention anything about the TRIGGER-SW, (below the relay) but after playing around, I have found that shorting the centre pin and the upper pin MOMENTARILY will re-start the timer - either of the poles of the switch will work), (The bottom switch pins do nothing).
This is an important omission in the product description and instructions because this means that a remote switch could be introduced to re-start the timer and thus make it more useful in other applications also. Cheers,
Derrick
Used as a solar triggered WiFi Daylight control. To reverse the relay operation Just exchange the 5Y3 transistor (NPN) for a (PNP) generic transistor such as a 2n2907. I used an A56. Be sure to exchange the emitter and collector leads.
