Power Plant pro in constant boost mode

I’m pretty sure I’m going to have to send my older power plant pro in for repairs but it will be a few months before I’m able to. The issue is it is in constant boost mode, it amplifies the incoming THD and power output. Input power is 120 out put power is 125 input THD is 3.5 output THD is 4.0. In the meantime is their any type of button combination or remote command I can do to take it out of boost mode? I’ve already tried turning the big screw under the power plant and it has no effect.

It sounds to me that the regenerator has failed. I do not know of any way to defeat any of its operation.

I would stop using it and send it in when you can.
