Blackguard, deliver the facts of your case not inane dog tails, you wannabe.
The cabin temperature can be effectively controlled by the FAP with no input from the flight deck.
The FAP has an adjustment range of +/- 3 deg.C of the temp.set in the flight deck which has a rotary select knob with a range of 18-30 deg. C.
If as it seems you don't know that, then for everyones sake, stay away from the FAP. You are probably the cause not the fix. If you have suffered through a 'cold spell' and not asked the Flt deck for help with the temperature control, then you're a goose.
