Baxi 105e - which pump?

[NatB]

Hi
Looking to replace the pump head on my Baxi 105e combi but I'm not sure of the pump I need.

The manual indicates Grundfos 15-60 GC E66 530 manufacturers part number 248042 which also incorporates a speed selection switch.

The pump on the boiler is a Grundfos 15-60 AO P/N 59926512 which doesn't have a speed switch.

Anyone know the definite part number that incorporates the speed switch?

If the new head has a speed setting it's ok, just make sure it's on 3

If there is a speed switch, set it to 3.If there isnt one it is already set to 3
