If the Environmental system is selected to the Manual mode, the crew
can directly adjust each TMV. Each push of the Cold or Hot button
drives the valve in the appropriate direction for a short time. If the duct
temperature is driven beyond approximately 93 °C, the valve will
automatically drive to the full cold position after which the valve
position can be adjusted again. Duct temperature is not an indicator of air
temperature entering the cockpit.
