Temperature Selection

The temperature selector is electrically linked to the hot and cold air
valves. Rotating the selector simultaneously opens and closes the two
valves, permitting hot and cold air to mix and enter the distribution
system. Rotating the selector clockwise, permits warmer air to enter
the system - counterclockwise, cooler air.
On airplane with the optional Air Conditioning System installed, when
the air conditioning button (snowflake) is pushed, the valve on the
firewall completely closes and the air-conditioner is activated. When
recirculation button is pushed, the fresh air valve completely closes
and cabin air is recirculated to provide for maximum air conditioning
operation. When the air conditioning system is on and the temperature
selector is rotated to the full cool position, recirculating mode can be
activated to provide maximum cabin cooling. Air conditioning or
recirculating mode is not available when the airflow fan selector is in
the "0" position. Recirculating mode is not available unless the air
conditioning system is operating.
