HiDoes anyone know anything about the V series controllers. our has a pressure warning and no longer useable. If any one has had the same problem please could they feedback any input they may have.
Lee you are the expert on gas boilers not controllers. Or was it controller aswell.
Had it once, and sure it was just calibration that sorted it.Silly question, but have you set it lower and higher?
Why is the pressure warning not working? Are you sure it's not your pressure switch
I had a problem with a controller that was stuck on PS and the controller was broken so I had to replace it You can use the controller without the pressure switch connected. Try disconnecting it and running the pump straight to the controller and see if the PS error
