Window comparator

I have problems understanding my Metabolic Devices 2Win.
If input 2 is at 3v and window size is 1v the output gets high when input 1 is between 2v and 4v.
But how do I get a high output only if input 1 is higher than for example 3v?
And the opposite: a high output only if input 1 is lower than 3v?

If input 2 is at C volts and window size is W volts, the output is high when input 1 is between C-W and C+W.

So for your first example, set input 2 to 4V and window size to 1V to get a range of 3V to 5V.

For your second example, set input 2 to 1.5V and window size to 1.5V to get a range of 0V to 3V (or adjust as needed if you want the range to start at a negative voltage).

Thank you very much piragde!
Now I understand how to think.
