If I had to guess, you're missing a property that's required.

Like I said before, I don't know of anyone running phosphor-pid like you
are hoping to.  The "default" is to run in cascade loop mode, and all
the existing systems are examples of that configuration.  It's likely
time for you to break out GDB and start debugging your configuration.

Alternatively, approximating your fans as linear, and using that as the
output targets would likely get you to a working thermal solution faster
than going down the path you're going.
