Hi, I have a ceiling mounted bathroom extractor fan which I inherited with the house - it is situated above the bath which does not help when attempting to take a good look at it! The problem being that the timer comes on immediately on the light pull cord and continues to run for up to 5 minutes after turning off the light. I would like to reduce the timer settings to come on much later if able and turn off when the light is turned off too. I have removed the hood but I have to really screw my neck around to view the components. The only thing I can see is that it is a Newlec, with many fiddly switches. Which switch do I need to fiddle with please to reset the timer?
