Hi there, we have the danfoss fp715 central heating/ hot water controller connected to our boiler. All has been fine with it until today. This morning when it was set for the hot water to come on the radiators came on instead. I have tried several times to turn the hot water on manually but each time the central heating comes on instead. I have looked at the danfoss website and read the user guide and as a result I have tried pressing the reset button to restore factory settings. This has made no difference to the problem. Anybody have ay ideas whether its a fault with the boiler or the controller? Anu solutions? Cheers Simon
