Instructions for the
Outdoor Lighting Timer with Light Sensor
HB51RC75
1. Before installing your Outdoor Timer with Light Sensor,
it is important to keep your timer from:
a. the lights being timed ON/OFF
b. other night time light sources, e.g. street lights, porch lights
c. reflective surfaces such as aluminum siding
(Please refer to Item 2 under Other Important Notes)
For this reason, it is recommended that a 3-conductor grounded
outdoor extension cord be used between the timer and the lights.
2. If you are using an outdoor extension cord, plug it into your timer
receptacle. If you are not using an outdoor extension cord, plug your
outdoor Christmas or other incandescent lights into your timer
receptacle. The total cumulative wattage of all the lights must not
exceed 1000 watts.
3. Plug the timer into a grounded 120 volt outlet.
OPERATING INSTRUCTIONS
AFTER THE LIGHT SENSOR SENSES DARKNESS, YOUR
TIMER WILL TAKE APPROXIMATELY TWO (2) MINUTES
BEFORE TURNING THE LIGHTS ON. THIS IS TO ENSURE
THAT THE LIGHTS WILL NOT TURN ON IN A REACTION
TO TEMPORARY DARKNESS.
IMPORTANT NOTE:

OTHER IMPORTANT NOTES:
1. For best results, plug your timer directly into a grounded 120 volt
wall receptacle that is at least 1 or 2 feet above the ground.
This prevents snow accumulation on the timer.
2. The light sensor initiates the timing cycle. Shield the sensor from
all night time sources of light. The timer will shut your lights off
if the sensor is influenced by the outdoor lights being timed, porch
lights, street lights, car headlights, etc. When this occurs, the timer
will reset itself and when the light source is removed, the selected
run period will be repeated.
3. If you are installing the timer in a non-lighted garage, work shed,
etc., it is necessary that the sensor face a window. It is important
that daylight is allowed to reset the timer for the next evening.
Otherwise, your lights will not come back on.
4. If a power failure occurs: After the power is restored, the timer
will automatically default to the preset operating program.
If it is dark: The unit will immediately turn the lights on and they
will stay on in accordance with the preset operating program.
If it is daylight: Your lights will remain on for a minute or two and
will then turn off. Then, at dusk, your lights will automatically
turn on and will stay on in accordance with the preset program.
