Pump speed on combi boiler

[Johnytuono]

WB 30kw Si compact boiler (about 12 years old) that supplies heating and hot water.
The pump is a 15/60 3 Speed Bosch.
If I set the pump to Speed 2 (or 1 even) for the CH, does it always use Speed 3 for heating the DHW?
Can't seem to find the answer anywhere.
Thanks

If the speed is a manual setting the Ito, use that setting, so no it wouldn’t use speed 3 for dhw

No, it'll use the same speed for both
