Recirculated air mode or outside air mode may be automatically switched in
accordance with under these condition, such as temperature setting and
inside temperature.
Also, outside air mode may be automatically switched to when the outside
temperature is low.
■When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on
●In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the “POWER”
