Works well but read the instructions carefully and don't lose them!
on 6 November 2013
I have four of these units. I purchased them because we have so many power cuts here that the ordinary mechanical timers are often not set to the correct times.
The first one I received did not seem to work at all (the display seemed to be frozen) but apparently you should first press the small reset button (above the week button) if this happens when the unit is first charged up (with a pencil or pen as it is recessed) as the instructions say . After this, all the functions work properly.
Having done this, set the current time and day by pressing the clock button followed by the hours and minutes buttons and set the day of the week by pressing the week button until the correct day is selected.(note you can easily change the settings for GMT or British Summer time ,see instructions).
The unit has ten program settings (i.e. times that you can switch a connected device on and off). It can be set to come on daily, or in groups of days or on a specific day of the week. To setup the program times press the timer button followed by the week button to select the day or days, followed by hours and minute buttons to set the "on" and "off" times . Make sure that when you set the "on" time for a specific day or period, that you set the "off" time for the same day or period. I did not do this the first time I used the timer and as a result the unit did not switch off on the same day. Seems obvious I know, but it is an easy and frustrating mistake to make.
The other thing to note is that there is a random button to make it operate at random times. I did not notice this at first and had accidently pressed it and as a result the units were not turning off when I had planned but much earlier. A small letter R is shown in the display if you press the R button. De-select it if you did not mean to use it.
Make sure you leave it set to auto after you have finished setting up the program times. It can be operated manually as well as by the programs.
The unit will operate modern low energy lights as well as ordinary lights (it has a relay inside which clicks the supply on and off) but it is NOT suitable for high energy loads such as emersion heaters or kettles or washing machines or any device that has a heating element inside it.
