The pump on my Baxi Genesis 80 combi boiler is supposed to be 2 speed
according to specs.

There is however, no obvious way of increasing the speed or even
checking what speed is selected.

There is no switch or anything.

Is there a hidden method of selecting the speed?

If so, how is it done?

I have a large house with some long pipe runs and I want to ensure the
pump is running at it's maximum speed.

The G.C. number for the pump is 277-862.
Manufacturers part no. 235878.



Thanks,


Steve.....
