00103 OperationMode
A state to control the operating mode of the booster system.
0: Auto-control (setpoint control according to selected control
mode)
4: OpenLoopMin (running at minimum speed)
6: OpenLoopMax (running at maximum speed).
Note that "OnOffReq" has higher priority than the OperationMode,
meaning that you must set "OnOffReq" to "On" for the
OperationMode to have any effect.
The Hydro Multi-B can only run in auto-control mode.
The Hydro Multi-E model G can only run in auto-control mode and
OpenLoopMax.

MPC, Multi-E: Percentage of closed-loop feedback sensor
maximum value.
TPED, MAGNA3-D: Percentage of the setpoint range.
Open loop:
