Irritrol TC-24EX-R gets gibberish settings

Every month or two, one circuit on a quite new Irritrol TC-24EX-R suddenly develops gibberish settings which leave the valve running (who knows how long?) until I notice it in the morning.

It happened today, again, and I went through all programs and times, and noticed that the time settings for the valve in question (today, 14) were messed up in all four programs ABCD in' "Station Times". Messed up means not only a different time from what was originally programmed, but times that are impossible (42 hours and 78 minutes) and even partially disrupted characters (0 with no top, for example).

Everything else in the programming was fine.

Is this unit defective and should be replaced? Sunspots? Power line noise (we did have thunderstorms and a brief power outage earlier this week)?

Is there a way to reboot, and would that be worthwhile?

thanks for suggestions!

Pretty much all you need to know.

To erase program information for a selected program:
1. Select Program A, B, C or D with the Program switch.
2. Turn the function dial to the Program Erase position. The display will show “ERASE.”
3. Press and hold the OFF button until “ DONE ” is displayed.
4. Repeat this procedure for each program you wish to erase.

Timer

You can unplug the ribbon cable from the circuit board and remove the battery for 45 min to an hour. Also try clearing the programs like Wetboots suggested. If that doesn't fix it, you may just need a new timer face. Is it older than five years?

I want to thank irrigirl for this one. I have an Irritrol TC-24EX-R and was about to purchase another controller. My GFCI circuit goes out once in awhile. We've had sufficient rain, so I'd not worried about irrigation in VA until I started the garden. The controller was out of wack...showing blinking minutes section of the time, as if you were in the time setting mode, wouldn't start a program, showing time on single station, etc. I unplugged the ribbon cable and put it back in...all is well now. This forum saved me $378 today--Thank you!!
