By your description, the doser is already powered ON.

- Do a PAB-system reset and re-assign all PAB devices via GCC.
The system reset option can be found in the SYSTEM settings page, to the right.

That does not work...

Let me explain step by step so you understand the situation.

I had my Doser hooked up to socket 2. In slave mode. Everything worked.

I followed the YouTube instructions to setup a head as an ATO. My doser is not currently dosing anything. Just being used as an ATO on a new tank.

Once I set the doser up as an ATO the socket only comes on when the level control detects low water. It comes on with low water and works perfect as an ATO. Once the level control than detects water is OK it shuts off socket 2 and I get a Pabcom error.

I did manage to manually override the socket and turned on socket 2 so I could reset pab devices. That did not help.... once it runs as an ATO it sends a PabCom error when the ATO is not active.

I was able to duplicate this exact issue on my second P4 and doser on my display tank. I normally run a stand alone ATO on this tank but just to see I tried it... same exact error. P4 and Doser 2. I don't have the doser 2.1.
