The Intermatic digital seven-day programmable wall switch timer controls lighting, including fluorescent, and heavy-duty loads such as fans and appliances. The device can be used with four separate programming options: same settings Monday through Friday; Saturday and Sunday; all 7 days of the week; and individual daily settings. The timer features an LCD digital clock readout, as well as to-the-minute accuracy. Program up to six on/off settings per seven-day period accurately to the exact minute, and a total of 42 on/off settings per week. Other features include manual override, easy-to-set six-button programming, battery backup, and a random setting feature, available to avoid predictable timer-controlled look. The product also maintains programming up to three years (even during power failures), and includes a 1-year limited manufacturer's warranty.
