Hello,
I have an PRO 4PM and on the same phase there is an water pump for the gardening. Both devices are not connected to each other they only share the same phase. The problem is that when the pump gets switched on, it draws so much power that I get an undervoltage, then when the pump is switched off, the PRO 4PM does not recover and the device needs reboot. I had set the undervoltage to 190V and have checked the box for the recovery
