Question
I don't have model# or a timer cover for that matter but maybe you could guess? I have 6 zones but i don't need zones 4 and 6 so i don't have them set on the timer. Problem is zones 1 , 2, & 3 work fine, but the timer seems to stop after 3 and i can't get zone 5 to come on. Any suggestions?

Answer
Hey Brian, it could be that your valve #5 is not working or your controller is not sending out a signal to valve #5. The easiest thing to try, is take the field wire off terminal #5 and take the field wire off terminal #1 and now put the field wire you took off of terminal #5 and put it on terminal #1. Now turn of zone #1 and see if valve #5 comes on. If valve #5 works, then you have a problem with the controller, if it doesn't work, then you have a problem with either valve #5 or the wires running to valve #5. Try this and let me know if you need anymore help. Thanks and have a great day.
