The Intermatic EI400LAC Digital Auto-Off Timer is easy to install and absolutely silent to operate. Functions to control all voltages and frequencies (within the contact ratings) with no adjustments required. Comes with a factory supplied CR2 lithium battery which provides up to three years of time keeping without AC power and the user program selection is stored in non-volatile memory. A low battery indicator appears in the display when the battery requires replacement. It also features a field selectable warning that provides an audible and/or visual signal that the load is about to switch off. This timer offers "true" 3-way control allowing the load interval to be started and stopped using a standard mechanical switch.
