Thank you! 
I have read it :  https://github.com/openbmc/entity-manager/blob/master/configurations/R1000%20Chassis.json
But I don't understand,

Is there an explanation for this part?

Are there general instructions on how to control fan output by temperature?



and how to use phosphor-pid-control  to set this ?
 
Is there“ phosphor-pid-control ”the instructions for this part?
Thank you very much !

This is using temperature values to control the fans so as to cool
down, it works by configuring phosphor-pid-control appropriately, I
hope it's enough of an example:

If you think phosphor-pid-control is missing some documentation please
read its source code and send documentation patches for review.
