You are here:

Irrigation/TMC 212


System starts and runs properly at programmed time.
It has run properly for 2-3 years.

Now, it unexpectedly turns on shortly after midnight.

Why? How can I fix this.

Hey James, make sure that you do not have a second, third, or fourth start time scheduled in on start times. Also go through your b and c programs and make sure you do not have something scheduled into these programs. If you have a start time scheduled in on the second, third, or fourth start time, simply hold down the + button and the - button at the same time, and it will clear that time out. Good luck and have a great day.

Any question regarding sprinking systems,installation,repair, and trouble shooting.


I have been installing and repairing sprinkling systems since I was 15 years old. Have owned my own sprinkler system contracting business for over 26 years. It is basically the only job I've ever done, except for being a paper boy when I was young.
