The sensor wall plate accommodates the NEMA standard 2 x 4junction box. The sensor can be mounted directly on the wall surface if acceptable by local codes.Do not mount the sensor in drafty locations such as near air conditioning or heating ducts, over heatsources such as baseboard heaters, radiators, or directly above wall mounted lighting dimmers. Donot mount the sensor near a window that may be opened, or near a wall corner or door. Sensorsmounted in these areas will have inaccurate and erratic sensor readings.Mount the sensor approximately 5 ft from the floor, in an area representing the average temperaturein the space. Allow at least 4 ft between the sensor and any corner and mount the sensor at least 2 ftfrom an open doorway.Note: Clean sensor with damp cloth only.
