Apparatus arranged with plural diverse-type detectors for controlling an electrical load

An apparatus for controlling an electrical load for the environmental control of a room, the apparatus comprising:

• an occupancy sensor including a thermopile array, the occupancy sensor is responsive to the presence of a person within a detection field of the occupancy sensor;
• a user-programmable controller arranged to receive a detection signal from the occupancy sensor and to generate a control signal for the electrical load, and
• an input device,
• wherein the controller is configured to store data indicative of a priority location within the detection field of the occupancy sensor by receiving from the input device an input signal while receiving from the occupancy sensor a detection signal indicative of the presence of the person at the priority location, and
• wherein the controller is configured subsequently to generate the control signal in response to a detection signal from the occupancy sensor indicative of the detection of the person at the priority location.

An apparatus for controlling an electrical load of a room, the apparatus comprising:

• and
• a controller arranged to receive a detection signal from the occupancy sensor and to generate a control signal for the electrical load,
• wherein the controller is adapted to store data indicative of a priority location within the occupancy detection field to generate a second control signal in response to receiving the detection signal from the occupancy sensor indicative of detection of the person at the priority location,
• wherein the controller is further adapted to store the data indicative of the priority location in response to repeated detection by the occupancy sensor of the person at the priority location.
