1. The outside temperature is above 32°F.
2. The passenger's area temperature has
reached 7°F under the set point. At this
moment, enough heat is available from the
engine to warm up the area while the air
conditioning will remove moisture in air and
prevent fogging up of the windows.
The vehicle is slightly pressurized by the HVAC
system to prevent dust and moisture from
entering.
NOTE
Upon starting if the outside temperature is
above 32°F and then drops below 32°F, the
compressor
will keep running up to a
temperature of 15°F to prevent condensation
from forming on the windows.
