Hi, I would be extremely grateful if anyone could help me with this problem.
I have just replaced my programmer because the hot and cold water on lights were dim and I had no hot water or central heating, the programmer was old and the swithes felt a bit funny when you pressed them.
I replaced the programmer with a Drayton LP241 making sure the backplate was the same and the fully pumped system switch mode was on.
When I switched the electricity back on it just flashes on the display.
Any advice would be greatly appreciated
