- 15. A method for controlling the temperature of a seat having a lower surface and an upper sitting surface comprising an electrical heater, cooling means, and a detector operatively disposed for detecting a temperature of said electrical heater, and said electrical heater and said cooling means are actuated based upon said detected temperature, said method comprising detecting a first temperature, supplying a predetermined power to said electrical heater, detecting a second temperature at a predetermined time period after said detecting of said first temperature, detecting the temperature difference between said first temperature and said second temperature, determining the humidity content of air from said first and second temperatures and said predetermined power, determining a predetermined time period based upon said humidity content of said air and said first and second temperatures and said predetermined power, and controlling said electrical heater and said cooling means based upon said predetermined time period whereby the humidity content of said air is eliminated.
