rewiring might demand expensive labor and sometimes is not necessarily possible because of limitations as to what can be done structurally to the respective room combining the parts of a fan switch or timer with a sensor an actuating device controller transceiver and or keyboard may elegantly solve this dilemma and create competitive advantages because of greatly reduced costs of adding for instance an indoor air quality sensor and one or more mechanisms to an existing enclosure of a room there may be an integration of a relay a fet or triac to operate a fan load a keyboard an indicator control circuitry a transceiver and possibly other components into a control assembly or interface a user actuated interface may be used to select a status and a power supply to operate this device adding a wired or wireless communication capability to signal the status of the indoor air quality and the fan to one or multiple auxiliary locations such as a central status monitoring system may be incorporated the communication capability to allow control and configuration of the fan actuating device from remote locations may be utilized the communication capability to control other devices in a building automation system by assigning additional functions to the buttons of the device may be utilized the present device may feature a fan actuator a sensor an rf wireless radio subsystem and importantly have a replacement of a switch timer or other existing component in a single gang electrical box without needing further fabrication u201c single gang u201d is a term of art in the electrician and construction communities that refers to.
