Default: 3.0, Range: -9999.0 through 9999.0
Proportional band value is equivalent to the throttling range.

use zero. This does not apply to Derivative or Integral.
Derivative time Tv Number type: whole number, Unit: seconds
Default: 10 sec, Range: 0 through 7200 sec
Integral action time Tn Number type: whole number, Unit: seconds

If Integral action time is less than 15 seconds, integral control is disabled. If you set
Integral action time to zero, software sets the P2 parameter to 1,000,000. A number
this large effectively disables the integral term.
