and what does it do and when ?

I thought you ordered your car from new? If you've never run it it prolly won't work now anyway. These type heat your coolant to around 60 degs so it's all warm before you start the engine. I think you should of had an extra key fob type thing that controlled it.
Also possible to get a timer unit from Webasto and a 7 day programmable type too i think
