    Anyone tried the Atoko Fan Select (ATQ6-03) - extractor fan timer - switch fan off during run-on?

    Hi. Has anyone tried the Atoko Fan Select (ATQ6-03)? Its supposed to be an extractor fan timer so you can get delayed start and run-on using a standard fan. They say you can also override the delay and run-on by switching the light - does that really work?
