How do I decipher Wilo pump numbers?
As an example what is the difference between a WILO ST 20/6-3 P and a WILO ST 20/7-3 C or a WILO ST 25/7-3 P
Some pumps mention "2,6uF - 400VDB / ~ 230V - 50Hz" on the front panel, is this the start capacitor value?
Thanks!

Hello
My pump makes an odd sound... see attached file. Is this normal? Tried venting/bleeding it but no difference. Same sound whether the hot water or CH is on. Changing the pump speed doesn't help.
Thanks

Hello
When I choose the the venting function what does it actually do? Do the pump have its own vent hole? Do I need to vent the radiators while it's doing this?
Thanks
