Occupancy and light sensors explained:

The sensors respond to motion, switching lights on, when entering an area. When leaving the area it is not immediately plunged into darkness, the lights switch off at a predetermined time. The time delay may be adjusted. Sensors measure light levels in the room and dim or switch off the lights, should sufficient natural light be available. The sensors may be set to control office air conditioners for even higher energy saving. The 'on time' of the air conditioners, may be selected via a second channel time setting. These features are all selected via a simple to use remote control. (No step ladders or tools needed.)

About Heat Pump Technology:

Heat pumps are widely used all over the world to heat water. Energy savings come about because it is more efficient to separate hot molecules from cold in a fluid medium (such as air) than it is to make the medium hotter by using direct heating, such as an electric heating element.
