Premise heating device, has luminosity, movement and noise detection sensors that detect actual presence of person inside room to be heated, for adapting electric heating mode to comfort mode or economic mode
The device has a luminosity detection sensor (1) e.g. photo resistor, a movement detection sensor (2) e.g. photovoltaic cell, and a noise detection sensor (3) e.g. electret-foil microphone, that are connected to signal shaping and amplification circuits (11-13). Signals shaped by the circuits are introduced in a microcontroller type programmed processing unit (14) for performing a predetermined operating algorithm. The sensors detect actual presence of a person inside a room to be heated, for adapting an electric heating mode to a comfort mode or an economic mode.
