How do I connect a Siemens Room Thermostat

My Son in Law who lives 200 miles away has asked me by phone how he can replace an old room thermostat with a new Siemans RAA 20 room thermostat. He is confused by the different coloured cables.I have replaced several thermostats myself but unable to help on this occasion. Can anyone tell which coloured wires go where. Thank you

Some Seimens room stats do not have an anticipator so it does not require the blue neutral wire. I also think it may not require the earth but check the instructions.There should be 2 wires left these should be used
