'BING-BONG' 'Es ist sehr kalt hier'
To clear up the confusion over the 'controllers' on the 400, 8 and 900 - there are 2 CONTROLLERS (each with a 'standby' function) but 3 TEMPERATURE SELECTORS. Controller 1 controls the left pack, controller 2 the right - The 'CONT CAB'
selector controls the flight deck air (as per older models). The 'AFT CAB'
selector controls air to the Rear cabin by controlling the right pack (ditto). The 'FWD CAB'
selector twiddles the output of both packs to attempt to control the front of the cabin (but inevitably messes up the comfy cockpit and the rear cabin
)
So, for simple pilots there are 3 'controllers'. For the clever techies there are 3 'selectors' but 2 'controllers'.
EDIT 1: To confirm what Denti says - the 'AUTO' merely shows the range in which the selector is supposed to work automatically, ie between 'C' and 'W' and is not a specific 'setting'. However, the 'AUTO' position (ie 12 o'clock) is a good starting point for an 'average' pax load.
EDIT 2: Denti - 'roger'.
