4 How to activate LCD using the light sensor
The light sensor is recessed under the small round hole near the center of the dial face. The hole is
marked with a light bulb graphic (see figure). The light sensor activates the LCD display for several
minutes when the unit is exposed to a light source. For example, a unit mounted in the basement would
turn on the LCD for several minutes after the room light is turned on. A unit mounted in an outside pit
would turn on the LCD for several minutes after the pit lid is opened exposing the unit to daylight. If the
LCD is currently off, the LCD may be reactivated by covering the dial plate with your hand for about two
seconds. In bright sunlight, it may be necessary to close the cover or the pit lid momentarily. If the LCD
does not reactivate as expected, try shining a flashlight on the light sensor.
