How can setup pressuretrol controller PA404A 1009?

I saw that my heating system turn on in the next setups, but I don't know which is the correct?

1. Differential dial on 2 and PSI on 9

2. Differential dial on 3 and PSI on 8

3. Differential dial on 4 and PSI on 6.5

4. Differential dial on 5 and PSI on 6

Thank you

    Differential 1.

    1 PSI.

    The lower, the better. But, these controls have trouble running too low. So, stick to the above numbers.
