hi, I have a problem with my heating not turning off once it has been on. What happens is I can use my hot water with no problems and can switch it on and off freely. Once I use the heating it will always come on with the hot water and cant be turned off unless the hot water goes off. The only other way is to turn the power off which closes the valve to the heating. As this closes the valve the next time I use the hot water the heating won’t stay on again until it is used and then the issue starts again.
I had a quick look and thought that the motor on the 3 port valve had broken so I replaced that but still had the issue. My next thought was that the signal was getting sent to turn the heating on (and the valve opened) but there may not be a signal being sent to close the valve. I needed a new programmer anyway so decided to put a new one in to see if it would solve the problem but still no joy.
I am now running out of options and don’t know what else could be causing the problem. The valve is definitely opening and closing freely so it does appear to be a signal issue but I am no plumber or electrician. Please could you give me your thought on this.
