The Maintenance Manual states that the Zone temp Bulbs send a signal to the EICAS computers. I am going back to work tomorrow and I will check myself, but I was wondering if someone knew off the head if this is true. I always thought it was only duct temperature. And I can't find anything in the wiring diagrams that support the zone temp being displayed on EICAS. I know Duct temp is there, but don't remember Zone temp being there. Maybe it's an option on some aircraft.
My Maintenance training manual also makes no mention of the Zone Temp indicated on EICAS.
