Adjusting the Light Sensor

The light sensor can be adjusted for variable degrees of sensitivity. The sensitivity adjustment screw is located on the side of the thermostat, as illustrated below. Turning the screw clockwise increases the sensitivity of the sensor to light.

To check for correct sensitivity, place the thermostat in the Program On mode. When the lights are on the thermostat should enter Occupied 1 and blink the Occupied 1 icon. If the thermostat does not enter Occupied 1 while the lights are on, use the supplied screw driver to turn the light sensor screw clockwise until the Occupied 1 icon appears on the display. The thermostat should enter an unoccupied period when the lights are off. If the sensor does not enter an unoccupied period when the lights are turned off, use the supplied screw driver to turn the light sensor screw counterclockwise until the Unoccupied icon appears on the display, with the lights off.
