We have multiple Rachio controllers, but our 16zone controller has ceased functioning suddenly. (In fact, it stopped working in the middle of a run.) I’ve done the following troubleshooting steps, but am at a loss for where to go from here:
- We have no master vavle
- Have manually triggered all 16 zones at the valves to ensure the valves function - water comes from all zones as expected when manually turned on
- Have connected the common and each zone wire (individually) to a low voltage signal device to actuate the valves not via any Rachio controller - each valve actuates as expected
- Have rebooted the device multiple times - device returns to normal state within a minute or so after reboot
- Have validated that the network connection is functional - the app can send a zone request and the controller receives it (blinking light on the appropriate zone), but the associated valve is not actuated
- Have connected the zone wiring to an adjacent controller and validated that each zone functions through the adjacent controller - the valves actuate when connected to the adjacent controller
I’m at a bit of a loss as to what else to do to troubleshoot. The issue seems to be with the controller itself, as I’ve been able to isolate all the other aspects of the system and they independently function. Any further advice or direction is great appreciated!
