The purpose of the presence detector with constant light control is to save energy by dimming/switching off lighting when unoccupied or when ambient light level is sufficient. Furthermore, it facilitates presence-dependent control of heating/ventilation systems in conjunction with the BLC relay/switch insert HVAC.

Application areas e.g. office buildings, schools, hotels and nursing homes.
