The alarm function will not be activated if the desired flow / duct
temperature is lower than the set value.

The pressure is measured by means of a pressure transmitter. The transmitter
sends the measured pressure as a 0-10 V or a 4-20 mA signal.
A voltage signal can be applied directly to input S7. A current signal is
converted by means of a resistor to a voltage and then applied to input S7.
The measured voltage on input S7 must be converted to a pressure value by
the controller. This and following 3 settings set up the scaling.
'Low X' defines the voltage value for the lowest pressure value ('Low Y').
