Hey there I'm experiencing a similar problem hope someone can help:
Suddendly the Uninet controller stopped connect to the system leading to continuously Uninet error 2000 coming out (Uninet controller is restarted). We had the same problem on and off in he past but we could solve it just running a manual run for a few second: after that all he components get connections to the system with the typical beeping and messages on the display.
This method unfortunately doesn't work anymore for some reason but if run a manual run only the UV detector makes the connection. After I stop the run message 2000 start appearing continuosly again with single errors 2012 related to faulty connection with any single component: error 2012 no response Pump, 0: error 2012 no response valve,1: error 2012 no response frac, 0.
I already tried to change the ethernet cable from the uninet controller to the pump module and I tried to bypass the mixer in the connection but I had the same result
