Subsequent adjustment occurs in stages, starting with the heating function. The heating unit (9) is arranged outside the air current produced for the ventilating and cooling functions. In the heating stage, the heating unit is arranged in the breast area (6) of the window of the room (1) at a distance from the floor, esp. a double floor (8). A free space between the heating unit and the floor is covered with a viewing screen (13).</p> |
