Byte 0/1 Switchover setpoint for the comparator (not used in variant -3AB31)
The value entered at channel 13 is supplied to a comparator along with the
switchover setpoint specified in units and converted to an analog value.
A maximum of 1024 units can be specified. The comparator output is set to 1 when
the switchover setpoint is reached.
If jumper D is inserted, the selected value (maximum 1024 units) corresponds to
an input value of maximum 20.48 V (corresponding to 2048 units).
