Hi

My controller have been doing some weird thing lately its changing time an going back to 1968 , i Don't know why, it do it random and have make this time 3 times in this month, is not a big deal cause i can set time back, but it might be a big deal if the dosing pumps were running.

Everytime i notice it because of lights on at rare time, right now it change time with no apparent reason, it was working fine and suddenly it turns off ATO lights an turn Leds on without been touch at all.

Why is this happening and how can solve it??

RTC related. Roberto will know more. That's exactly what was happening to me and could be related to expansion modules.

Any expansion module?

Possible to that your battery is dead and the RTC is "loosing" the time??

No, i don't have any expansion modules.

Can you check the battery voltage?
