One line not working

I have a Hardie TC 2400 that has worked for many years. But now one of the 24 lines ( #1) shows zero voltage when it is activated. All the others are showing the correct voltage level on my multimeter.

Can you suggest actions I need to take?

Thanks :)

You could try to reset the controller but I doubt that'll work.

I've seen the Irritrol controller's #1 stop working. I simply moved the wire to another slot and it worked for about 2 more years. I did have to replace it because it went kaput.

You could wire two zones together.
