There are 10 separate timers present in firmware, or more if you recompile it. The overview is present in following table:
I have made small demo video of four Period timers set with Period time to 2, 4, 8 and 16 seconds and Run time set to 1, 2, 4 and 8 seconds. As you see it on LEDs, they create a nice binary counter :). Just to say, the code of below wireless node is only capable to listen to commands from GW, and turn the attached relays On or Off based on received value. So no need to reprogram it in case of changes.
