Wilo pump speed setting

[mufc]

Hi All,

New to the site and have a question regarding my central heating system.
I reacently replaced a 3 year old (5m) terrier water pump that was siezed, with a Wilo (6m) pump.
wilo pump part # (wilo-star-rs25/6-130)

The question I have is that the Wilo has 3 speed settings and the manual says that setting 1 is the fastest.
When I look at the pump there are 3 lines. One short one, one medium one and one long one.

Can someone please tell me is it the long line or the short line that is the fastest speed..

Thanks in advance......

speed 3 careful though sticking it on full whack can sometimes cause problems in the system

Hi, thanks for reply..

My problem is that i need to know, if it is the long line for the fast speed or is it the short line for the fast speed.
At least on the terrier pump it said 1,2 and 3 in roman numerials (easy). this bloody pump has 3 lines at dirrerent lenghts. which is which?????

In the pic, is the fastest speed the long line on the left or the short line on the right

Cheers...
