Works well once understood
Works great,simple to wire up.HOWEVER if like me you are a good DIYer but not a professional electrician you may find this tip useful.It is easy to set the time span you require for the switch to shut off by setting four tiny keys clearly described in the leaflet BUT to do a final precise time they ask you to adjust a thumbwheel.Luckily its position is shown in the instructions as it is a reostat that can't be turned with a thumb!!.You have to use s small screwdriver and turn clockwise or anti-clockwise to set the duration.AGAIN HOWEVER the "thumbwheel" is mounted vertically and can be turned from either side so clockwise or anti-clockwise changes depending on which way you face it!!! .Useful?. Once I'd figured it out it works very well.Lets see how durable it is.
