Only series “HVAC”:
Adjustment Scaling factor of the analog channel via C027:
- C027 = 0.0 % ... 200.0 %
- Set-value input
- C027 = -200.0 % ... -0.1%
- Inverse setpoint input
Offset adjustment of the analog channel via C026:
The adjustment of -10.00 V ... + 10.00 V refers to an input voltage of 10 V.

Calibration when using a
PID controller If, for instance, the control range of a pressure control (C0005 = -6-) is to be limited to a value
lower than the rated sensor value, the effective pressure setpoint can be proportionally reduced
under C0027.
Example:
- Pressure sensor 0 - 200 mbar (= P
r
) at E1.
- Analog input of the pressure setpoint via terminal 8.
- The max. pressure is to be limited to 120 mbar under C0027:

Important - With C026 < 0 V, f
dmin
can fall below the value set under C010.
- With C005 = -0-, C026 and C027 are not active.
- C026 and C027 are only stored in parameter set 1.
- For terminal configurations with manual/remote changeover (C007 = -23- ... -27-):
- Change between motor potentiometer and manual/remote changeover via terminal (E1 ... E4).
- For terminal configurations with manual/remote changeover (C007 = -23- ... -27-, -46-) and the
control mode LECOM (C001 = -3-):
- Change between setpoint via master current (C046, process setpoint) and setpoint input
possible via terminal (E1 ... E4).
