Optimum Ideal Concord WRS 240B

Hello, I've being scouring the internet for some settings for the 'boiler thermostat'

I've copied this link from the same boiler model but instead of 240B it's 255A so very similar or close at least.

No fine points - it just keeps on working.
The dial gives approximate flow temperatures of
1 54
2 60
3 66
4 71
5 77
6 82 degrees C
For "summer" (hot water only) use 1 or 2.

What setting should it be on to avoid condensation in the burner box, It's currently on setting '3' which is 66 degrees. Should it be on 4?, is there any inherent advantage to that or will 3 be fine for all year round.

King Regards
