17.1.1 Analogue inputs AI
AI1:
Sign: Outd temp
Raw value: 18.4
Compensation:0.0 °C
All analogue inputs are for PT1000 or 0…10 V.
Input signals can be compensated e.g. for wiring resistance.
The raw value will show the actual, uncompensated input value.
If inputs have been assigned to pressure or flow control of fans, alternatively humidity or CO

control, the following menus will appear:
SAF Pressure at
0 V: 0.0 Pa
10 V:500.0 Pa
Filter factor: 0.2
CO2 at
0V: 0.0 ppm
10V: 2000 ppm
Filter factor: 0.2
Set the parameter values that should correspond to the input signal levels 0 V and 10 V.
The filter factor is the damping you want the program to work with in order to reduce the influence
of potential signal fluctuations on the sensor input. The filter factor can be changed via the display
or E tool

and is found after ”analogue inputs” in ”configuration”. A new value is calculated using
the following formula:
New value = old value * filter factor + raw value * (1 - filter factor)
17.1.2 Digital inputs DI

NO/NC: NO Signal:
Filter guard1
Status: No
To simplify adaptation to external functions, all digital inputs can be configured to be either
normally open, NO, or normally closed, NC.
The inputs are as standard normally open, i. e. if the input is closed, the function connected to the
input in Corrigo is activated.
Be careful when changing the input from NO to NC since some digital functions can be configured
to either NO or NC themselves. For example, you can choose if the Fire alarm input should be
activated when it is closed or opened. Therefore, there is a risk that the signal is changed twice and
the result is the opposite of the desired.
17.1.3 Universal inputs UI
On the largest hardware version, E28 there are universal inputs. These can individually be
configured as either analogue inputs or as digital inputs. When configured as analogue inputs they
can be bound to any of the analogue signals described under Analogue signals.
When configured as digital inputs they can be bound to any of the digital signals described under
"Digital signals".
