Is there a warranty? Where can I get the service?

I don't know. I suppose, you have to contact original supplier or manufacturer..

How can i get din channel rail to install this switch?

You install this in a standard fuse / power distribution panel. You need a spare slot where you have your fuses / circuit breakers. If you are not familiar with electrics you need to get an electrician to install it

A small but powerful device

this device is very easy to program unlike the other ones which are extremely complicated the DIN rail mounting is another plus which makes it easy to mount multiple timers on one rail
