XPMT1 Mini-Timer can store "ON" and "OFF" times daily for installed Receiver Modules 1-8 in any configuration totaling 64 events. Manual Control is available for up to eight X10 addresses plus All Lights ON/All Units OFF. The X10 PRO Mini Timer controls up to 8 X10 PRO Modules automatically or instantly. You can have your outside lights as well as inside lights and appliances go on and off at preset times to give your home a lived-in look while you are away. You can program your Modules to go on and off at the same time every day or you can set your radio to wake you up “Once” only, for an early morning flight. There is even a "Security" Mode that automatically varies your programmed time each day so your home doesn't look like it's controlled by a timer. You can keep the Mini Timer by your bedside and it will wake you up on weekdays. It has a snooze feature so you can sleep a while longer and you can turn the alarm off on weekends. You can manually turn off your child's radio or night light from your bedside. You can turn on ALL lights connected to Lamp Modules and Wall Switch Modules with the touch of a button if you hear a suspicious noise at night. You can even turn off everything in the system with one button. Additional info: Optionally, the XPMT1 also functions as an alarm clock that can activate lightning in conjunction with a built-in beeper for unit number one. An option called Security can be used to vary the ON/OFF times so as to not appear to be a present timer and gives the lived-in-look to your home.
