Hello,i don't really understand (i've tried to check in the manual but i'm french and maybe i don't undertsand all), how to operate with air cond!1 - how can i change Pass cab temp (the temperature AFT pass cab fall near to 0° while climbing)2 - The other temperatures are good but if i set trim air button ON some of them climb very high! how to proceed in flight with this?and what is the trim air button use? thanks for your help!

Hi,Trim air should be on to regulate all the tempratures individualy. The climbing tempratoures are the the packs itselfe. The passenger temprature is controlled by the three switches. CAB, FWD, AFT. Cab is the Cockpit, FWD is the forward passenger cabin. And aft is the aft passenger cabin. Leave the switches in Automatic for the best result and set trimair to on. With the temprature gauge watch the CAB, FWD and AFT temperature. They should stay in normla ranges. The duct or the packtemperautres can be higher or lower, thats no problem. :smile:John

Well, i thought that the rotator swithch CONT FWD AFT (cab) was for the cockpit and the FWD AFT (pass cab) was for the passengers!i thought the knobs CONT FWD AFT were used fosetting the temperature on the cockpit!i still don't uderstand very well what temperture are dislayed (cont fwd aft) cabi don't understand the difference between the temperatures shown by (CONT FWD AFT) and (FWD AFT) sorry ...
