Murcia University has completed the installation in every classroom teacher presence pushbutton for air conditioning, to prevent it from running when the rooms remain empty for long time.
The air conditioning units in the classrooms are connected to a switch that when activated lights and runs for one hour, after which it automatically turns off.
This operation can be repeated as often as desired, without restriction of time, using the air only when really needed, which saves on cooling without compromising on the quality of teaching.
