Previously, this zone would not operate so I replaced the solenoid (didn't solve the problem) and then the diaphragm. The zone worked... for two cycles. Now, it will not shut off. I've done the following:
- reset the controller (disconnected the power, removed battery) and reprogrammed
- inspected the solenoid
- inspected the diaphragm
There is no voltage at the solenoid, so the controller is not asking the zone to run. Any thoughts?
