QuestionI have a Rainbird ESP controller with four modules set up. Zones 1 (4 valves), 3 (3 valves), and 4 (2 valves), all run-no problems. Zone 2 (3 valves) will not come on. When testing, error message, "NO MOD 1" comes up. All three valves can be turned on manually at the valve. Where do I start to resolve this problem? Thanks in advance!
AnswerIf this message appears and a module is installed, make sure the module inside the cabinet is securely connected and the black lever is in the locked position. And to be safe I would disconnect the power supply for a minute and let the timer reset itself in hopes of recognizing the mod after you are sure that it is securely fastened and the black lever is in the locked position.
