Essential Info

The EI400 series effectively replaces 16 different spring-wound models, freeing up additional shelf space, providing more specification flexibility, ease of installation and absolutely silent operation. A factory supplied CR2 lithium battery provides up to three years of time keeping without AC power and user program selection is stored in non-volatile memory. A low battery indicator appears in the display when the battery requires replacement. A field selectable warning feature provides an audible and/or visual signal that the load is about to switch off. Functions to control all voltages and frequencies (within the contact ratings) with no adjustments required. Provides true 3-way control allowing the load interval to be started and stopped using a standard mechanical switch.

This product is also available in ivory and light almond.

This timer can be used for controlling indoor lighting, outdoor lighting, pumps & fans, HID lighting, library lights, classroom lights, fluorescent lighting, PAR lights, heaters, recreational vehicles, air conditioners, porch lights, and carriage lights.
