Just some ideas:
- After the "weekly" setting You must set the days also. If You do not set the days, the programming will be incomplete, even it looks like completed.
- Try to "check" the timer settings, and see if there was a different timer setted before, which fe. shuts down the timer immediately, like "Timer 1 Play 06.00, and Timer 2 Stop 6.00". The BL7000 can handle a lot's of timer programs, so You must check ALL timer settings to be sure, there are no "crosslinked" timer settings.
- Also, please note, that the programs are not stored in the BL7000, but they are stored in the main systems. This means, if for example the main system has a power failure (and the backup battery is missing, or not working), or for any kind of error which clears the memory, then the timer programs will be lost, and You need to reprogram them.
- The date and time are stored in the main system and not in the BL7000, so as this values were surely cleared, or changed in the main system -> the reason used to be the same, IMHO a power failure, or some family member, who played a little bit with the remote :)
