My point is you can't have it both ways.i want the option to not run it off the light but understood you must run it off the lights in a bathroom with no window. hence my question to have both options one to comply with the rules and the other which is more practical in many ways....but you don't want it to run off the lights.as there is no window do i not have to have the fan run off the lights?
If you are that bothered about the regulation then you can't alter it at all.
Yes.would the run on timer still work if its switched directly?One for the light and one for the fan.what would be the best way to do this on a 2 gang switch?
Any fancy method will result in just as many switching operations - IMO.
What about a momentary switch for the fan - just a press when wanted and it runs for a set time?
