00202 ProcessFeedback
Indicates the actual process feedback from the booster system.
The scale is 0.01 %, so the valid value range is from 0 to 10000.
This value can be compared with the setpoint value.
Closed loop:
MPC, Multi-E: Percentage of closed-loop feedback sensor maximum
value.
TPED, MAGNA3-D: Percentage of the setpoint range.
Open loop:
MPC, Multi-E: Percentage of the maximum performance.
TPED, MAGNA3-D: Percentage of the nominal pump frequency.
Common examples
4700: 47 %
8000: 80 %.

00203 ControlMode
Indicates the actual control mode.
0: Constant speed
1: Constant frequency
3: Constant head
4: Constant pressure
5: Constant differential pressure
6: Proportional pressure
7: Constant flow
8: Constant temperature
10: Constant level
128: AUTO
ADAPT
(Automatic adaption for DDD)
129: FLOW
ADAPT
130: Closed-loop sensor
See section 10.1 Control modes.
Note that the control mode depends on the primary sensor, and not all
booster systems can run with all the control modes.
Note that DDD can run with constant pressure, proportional pressure
or automatic adaption.

00204 OperationMode
Indicates the actual operating mode.
0: Auto-control (setpoint control according to selected control mode)
4: OpenLoopMin (running at minimum speed)
6: OpenLoopMax (running at maximum speed).

00208 PumpsPresent
Indicates presence of pumps.
This value is bit-interpreted:
Bit 0: Pump 1
Bit 1: Pump 2
Bit 2: Pump 3
Bit 3: Pump 4
Bit 4: Pump 5
Bit 5: Pump 6
Bit 6: Pilot pump
Bit 7: Backup pump
A bit value of "1" indicates that the pump is present.
