This command starts LEARN.
With CONTROL MODE commands open valve or close valve the routine may be
interrupted.
Note: Without LEARN the PID controller is not able to perform pressure control.
Refer to «Learn (adaptive control algorithm)» for correct learn gas flow and procedure.

learn pressure limit according to selected DATA TYPE,
nominal pressure range is 0 … 10’000 (sensor full scale) but it may be scaled,
refer also to command GAIN for details.
This command transfers/reads the pressure limit for LEARN.
Note: Refer to «Learn (adaptive control algorithm)» for correct learn pressure limit setting.
