The control component may have new capabilities plus maintain the capabilities of the conventional component. The connection box need not be removed, or if the box is removed then the structure or space encompassing the box need not be enlarged. Further, no new wiring for is necessarily needed for connecting the control component. This placement or substitution may be particularly applicable to many rooms of hotels, motels, and other facilities. Neither time nor expense of modifications to the connection box, wiring and/or the room is necessarily needed. In many cases, a room or space cannot necessarily be modified to add a larger or an additional component having additional capabilities, such as a component having an air quality controlled device for operating a ventilation fan in a room. ## Claims ### Claim 1 A system for a control assembly, comprising: an electrical load situated in a room; a standard electrical box or standard electrical box space, situated in a wall of the room, for containing an ordinary electrical component for controlling electrical power to the electrical load; and a control assembly that fits in the standard electrical box or standard electrical box space in lieu of the ordinary electrical component; and wherein: the electrical load has electrical connections to the standard electrical box or standard electrical box space in the room; the electrical load comprises an air quality improvement mechanism; the control assembly is connectable with electrical connections to the standard electrical box or standard electrical box space in the room; and the control assembly comprises: an air quality sensor; and an electronic mechanism, for controlling the electrical load, connected to the air quality sensor. ### Claim 2 (depends on 1) The system of claim 1, wherein: the control assembly turns on the air quality improvement mechanism when the air quality sensor indicates an air quality index value lower than a first predetermined value; the control assembly turns off the air quality improvement mechanism when the air quality sensor indicates an air quality index value higher than a second predetermined value; the second predetermined value is greater than the first predetermined value; and air having an increasing air quality index value is air having a decreasing amount of pollutants. ### Claim 3 (depends on 1) The system of claim 1, wherein: the air quality sensor provides a value of an air quality index of a room; and the value of the air quality index indicates an occupancy state of a room. ### Claim 4 (depends on 1) The system of claim 1, wherein the room refers to a unit in a hotel, motel, multiplex residence, multi-party home, a single residence, private or commercial building space, or an integral room with in the unit. ### Claim 5 (depends on 1) The system of claim 1, wherein the standard electrical box is a single gang electrical box. ### Claim 6 (depends on 2) The system of claim 2, wherein the air quality improvement mechanism comprises a fan for ventilating the room. ### Claim 7 (depends on 1) The system of claim 1, wherein the electronic mechanism comprises: a microcontroller connected to the air quality sensor; a transmitter and/or receiver connected to the microcontroller; and a load actuator connected to the microcontroller; and wherein the load actuator is for connection to the electrical load. ### Claim 8 (depends on 1) The system of claim 1, wherein if the electronic mechanism is activated with a switch for effecting a certain action, then an indicator associated with the switch indicates that the action has been effected. ### Claim 9 (depends on 8) The system of claim 8, wherein if an action is effected with a switch, then the action is reported to a central building automation system. ### Claim 10 (depends on 9) The system of claim 9, wherein a signal for reporting an action to the central building automation system is communicated via a transmitter of the electronic mechanism to a receiver that receives the signal via a wire and/or wireless medium to the central building automation system. ### Claim 11 A method for installing a control component in a room, comprising: installing a control component in an existing electrical box or a space for an electrical box in a room of a hotel, motel, residence, or other facility; and wherein the control component comprises: an air quality sensor that indicates an amount of air pollutants in the room; and a load actuator, for turning on or off a load in the room, connected to the air quality sensor; and wherein the load is turned on or off according to an output of the air quality sensor. ### Claim 12 (depends on 11) The method of claim 11, wherein the load comprises a fan for ventilating the room to reduce the amount of air pollutants in the room. ### Claim 13 (depends on 11) The method of claim 11, wherein the electrical box is a single gang electrical box. ### Claim 14 (depends on 11) The method of claim 11, wherein the existing electrical box is designed for a holding a commonly available switch and/or timer as the load. ### Claim 15 (depends on 11) The method of claim 11, wherein the control component further comprises: a microcontroller connected to the load actuator and the air quality sensor; and a wireless transponder connected to the microcontroller for receiving signals to provide control of the load and/or for sending signals from the control component to provide indications of air quality in the room. ### Claim 16 (depends on 11) The method of claim 11, wherein: the air quality sensor provides a value of an air quality index of a room; and the value of the air quality index indicates an occupancy state of a room. ### Claim 17 An electrical assembly for a room, comprising: a control component for insertion in a single gang electrical box or single gang electrical box space of a room; and wherein the control component comprises: a controller; an air quality sensor connected to the controller; and a load actuator connected to the controller; and wherein the load actuator is for connection to an air quality improvement device in the room. ### Claim 18 (depends on 17) The assembly of claim 17, wherein the control component can replace an electrical component of the single gang electrical box. ### Claim 19 (depends on 17) The assembly of claim 17, wherein: the load actuator provides a power output for turning on the air quality improvement device when an output from the air quality sensor indicates a quality of air in the room as being below a first predetermined value; and the load actuator removes the power output for turning off the air quality improvement device when the output from the air quality sensor indicates the quality of air in the room as being above a second predetermined value. ### Claim 20 (depends on 17) The assembly of claim 17, wherein the air quality improvement device comprises a fan.
