If the pilot or passengers set the TEMP selector to the maximum heat position,
the bleed air system automatically switches from the P2.5 to the P3 bleed port to
increase the temperature and flow rate of the incoming bleed air. Except in the
case of very cold environmental conditions, this switching is inhibited below
25000 ft.
