You can set and activate seven predefined setpoints by combining
the input signals with digital inputs 2, 3 and 4 as shown in the table
below. Set the digital inputs 2, 3 and 4 to Predefined setpoints if
all seven predefined setpoints are to be used. You can also set one
or two of the digital inputs to Predefined setpoints. However, this
limits the number of predefined setpoints available.

Example
The figure shows how you can use the digital inputs to set seven
predefined setpoints. Digital input 2 is open, and digital inputs 3 and
4 are closed. If you compare with the table above, you can see that
Predefined setpoint 6 is activated.
