I have a 5+ year old flow controller thats a dial type, but does'nt override a pumps pressure switch, just bought a vyair pump and when the flow is turned down the pump does'nt switch off, causing my controller to get very hot (running it at full flow for time being so as not to burn it out)
My controller was one of the first crow electro ones (says essentially pure on it)
Does any supplier still sell a non digital controller that replaces pressure switch ?
DONT WANT A BYPASS SO PLEASE DONT SUGGEST IT

thanks,
Simon
