samples air from cockpit for temp modulation.
times when cockpit temp is difficult to maintain then take off cover and clean foam type insert.

Yep, standard stuff for any A/C temperature control system. A sampling fan draws air through a filter (foam in most Boeings) over the temperature control and indications sensors. Failure of the fan or blockage of the filter causes the sensors to mis-read. Single sheet loo paper is a good test :rolleyes:
