Press again (within 4 seconds after setting an On or Off time) until Security is 
shown in the display, to modify the program so that your lights (or appliances) 
will go on or off at a slightly different time every day (within the programmed 
hour). With each press the display shows whether you've selected Once, or 
Security. If neither Once nor Security is displayed, the event happens at the 
same time every day.

or Off time being displayed.

3. Wakeup

at the time programmed for Module number 1. When this sounds you can turn 
it off by pressing any button to obtain the “snooze” feature.  This will turn the 
buzzer back on in 10 minutes and will do so each time you operate snooze.

The alarm can be cancelled by moving the Buzzer switch to “OFF” and back 
to “ON” (for wake up the next morning).

4. Selector

instantly control Modules set to Unit Codes 1 thru 4 or 5 thru 8.  You can move 
the selector switch back and forth to achieve instant control of 8 

X10 

Modules. 

You can also move the switch during programming to select which modules 
(1-4 or 5-8) you are setting times for.

Setting the clock

Plug the Mini Timer into any convenient AC outlet. Fit two AA alkaline batteries in the 
battery compartment to protect the time and program for up to 48 hours in the event of 
a power outage.  If the battery is low, dead, or not installed, the low battery indicator will 
show in the display. 

When you fi rst plug in the Mini Timer the display fl ashes.  It also fl ashes if you have had a 
power outage and have not installed 2 AA alkaline batteries or if the batteries are dead.

1. Set the mode switch to “Clock Set.”

2. Press the top of the “Time” rocker to advance to the correct time. A 

quick press on the rocker will advance the time by 1 minute.  If you 
hold the rocker down the display will advance to the correct time 
faster.  If you overshoot, you can use the bottom rocker to go back.
