other devices you would operate at night.

It can be set to operate in one of three modes:

1) Continuously on from Dusk till Dawn

2) On at night limited by a program

3) Manually switched on

- It encounters the programmed off time

- You manually turn it off again

PROGRAMMING

By setting a program you limit the time the power can go occur between certain

hours. To do this you must first set the clock and then enter the time you would

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 DAWN MODE

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.
