P11 Plug Bar when power off

Hi all

Someone I know had their ATO stay on when the power to their P11 went off "filled the sump with Kalk"? on my P3 the plug bar switches off when no connection to the profilux? is this not the same fro the P2?

Thanks

The powerbar default state should probably be reset, in PLC look under "System" > "Socket Function" > "Program Digital Powerbar or Dosing Pump Unit" > "Initial State of a Powerbar".

Usualy people use this for a backup on there heater and there return pump

thank you so much
