Device and method for heating a vehicle seat

A device for heating a vehicle seat comprising:

• a. a heating element arranged in relation to the vehicle seat;
• b. a temperature sensor;
• c. a control unit connected to said heating element wherein said control unit comprises current feeding means to feed current through the heating element for the heating thereof, said temperature sensor connected to said control unit for detection of a temperature related to that of said heating element wherein said control unit is adapted for feeding said current if said detected temperature is lower than a predetermined desired temperature, and a communication unit;
• and
• d. an external operating unit wherein said communication unit receives data from said external operating unit via a transmission channel and said external operating unit is connected to at least one controllable functional unit for inputting to said external operating unit information relevant to the operation of said control unit, said external operating unit including programmed logic functions for generating said data at least depending on the state of said controllable functional units, and said external operating unit further including programmed functions for transmitting said data to said communication unit via said transmission channel, wherein said data comprises information related to said desired temperature, wherein said external operating unit is arranged so as to generate said data based on data stored in said external operating unit and being related to the design of said vehicle seat.
