I have a Potterton EP2002 Controller which does not switch off. I have had 3 in the last 12 months. They seem to work fine for around 3 months then they seem to get stuck in the on position. I replace the controller and it works fine again for it seems about 3 months.
Any others experiancing this problem or can offer a solution.
