Hmmm well it's off atm, my dodgy memory is there are simply 5 speed settings and I just click through them on the display. Edit, I see now there are 3 speeds I, II and III plus 3 little charts. I lazily haven't really explored these just used I and II. It's a Magna1. 2 wires to the boiler, job done! The boiler is 40kW Worcester Bosch 8000 life.
Using the WB smart controls it's never heating all the rooms at any one time - kitchen in the morning, living room in the afternoon etc etc.
The pump has to service an annex, cellar and 3 floors so the nice man at Grundfos wasn't leaving anything to chance I think
