I had a grundfos pump ups 15-60 and changed to new 25-55 180 pump - basically an upgrade Did the wiring on the pump and short circuited with the fuse downstairs tripping out.
EP 2000 potterton programme does not show any timings and the pump is not working. I think something has blown up in the programmer. Need help what should I look into. I have opened the ep 2000. Any help!!!
