Hi can anyone help. I have a fairly new ( 2 years old) complete hot water and central heating system. The only problem now is that the central heating comes on when only the hot water is on.
I have a drayton ma1 3 - port mid position valve and actuator. The actuator slider on the side moves to the correct positions when is supposed to but I am still getting hot water to the rads when the slider goes to the hot water side. I have taken off the actuator and turned the spindle but still the same.Does this indicate a valve fault as I am only able to turn it about 30 degrees which does'nt seem much to me.
Please post your comments Thanks.
