PROGRAMMING
By setting a program you limit the time the power can go occur between certain
hours. T
like it to go on and the time you would like it to go off. The power will be turned on
if it is dark and it is between the on and off time settings. The power will be turned
off when the off time is reached or when it is light again (which ever comes first)
For example if you set an on time of 6 pm and an off time of 9 pm and the sun
sets at 5 pm and rises at 6 am then the light will go on at 6pm and turn off at 9pm.
However if you are using the same six to nine program and the sun does not set
until 7:30 pm the timer will wait until dark to turn on (at 7:30 pm) and then off at 9
pm.
Please note that in the event of a power failure or if the on and off times are
identical the timer will go back to operating as a dawn to dusk timer
See the following example of program setting on pages 7 and 8.

DUSK TO DA
This timer is equipped with a photocell that senses ambient light levels. In dusk to
dawn mode, the timer will turn the power on when light levels drop and the unit is
in darkness and will turn off the power when it is light again. This is the default
setting of the timer and it will function in this mode when first plugged in.
The automatic on/off can be tested by covering up the photocell for 8 seconds to
turn the power on and exposing it to the light for 8 seconds to turn it off.
Please note that in the event of a power failure or if the ON and OFF times are
identical the timer will go back to operating as a dusk to dawn timer
