Negative control output

Describe the bug
Have to preface and say I'm very new to this PID thing, and I may not fully understand it.
I am trying to control a PWM fan in a TV cabinet, and thus using ac_mode: True
. I have NOT specified heater_inverted
, I've also tried to set this to true, but to no effect.
Is it expected to have a negative value when using ac_mode: True
?

Also having trouble with the set PID values (kp, ki, kd) not updating after reload, but I'm not sure if those are just cached in the UI.
Expected behavior
Expect control_output
to be a positive value.
I could potentially create a template
and use this to control the fan as a workaround? But I wonder if this is a bug or something I'm doing wrong.

Closing this since it's most probably not a bug? Will ask about my use case in discussions.
