5.2 Functions via the digital inputs
5.2.1 Evaluating the analog input
When a signal is applied to digital input X2b-D4 , analog input X3-S is evaluated. Depending on
the program, the analog signal is translated into a temperature or frequency setpoint. If no signal
is applied to X2b-D4 , the analog input is not evaluated. In this case, the corresponding setpoint
can be specified via the wired remote control.
Analog input evaluation is possible in the following programs:
– Program 0 and programs 2 to 9.
