Hi
Ive just replaced my mid position valve. Old was acl lifestyle and new drayton MA1 679-3. Programmer is a drayton tempus 6.
Ive now got the problem where everything works fine apart from one thing. The programmer now has no control over the hot water. Heating is fine.The hot water is always on but is being regulated by the cylinder stat so not a major issue but i want to get it back to on /off twice a day via programmer. I suspect a simple wiring fault as new valve is working fine.
Ive wired it as follows;
Grey - cylinder stat satisfied / HW off
White - room stat calling
Orange -cylinder stat calling / Live boiler
HW on - Cylinder stat common
N
E
The live pump wire was previously connected to a lone wire seperate from the rest so i have left that.
This replicates what was there previously and seems to match the instructions for the valve.
Programmer wired as follows
N
L
1.HW OFF
2.NIL
3.HW ON
4.CH ON
Any help is much appreciated.
