NOTES
Read these notes before continuing with the timer
installation and programming process.
• The timer is battery-powered and does not need
AC power for initial setup and programming. For
new installations, it is recommended that you setup
and program your timer before installing it.
• The battery controls the ON/OFF function (“click-
ing” sound) and maintains the time and date. The
screen flashes BATT when the battery strength is
low. When replacing the battery, disconnect AC
power. You will have a few minutes to insert new
batteries before the date and time settings are lost.
All other settings will remain in memory, without
battery or AC power.
• Each ON or OFF setting is an event. Each event
must be programmed separately.
• The MODE menu includes SETUP, PGM (program),
AUTO (automatic), RAND (random), and MAN
(manual). AUTO and RAND modes do not appear
on the menu options until the time of day is set and
at least one ON or OFF event is programmed.
• All menus loop (repeat options when you get to the
end of the menu). When in a specific Mode, press
ON/OFF to loop within that Mode.
• When using the
+
or
–
buttons to change a flashing
setting, hold the button to make the numbers scroll
faster.
• When advancing to the next setting, the timer au-
tomatically saves the data from the previous screen
whether you changed a setting or not. All settings
save automatically after five minutes.
