The EI40C effectively replaces 16
different spring-wound models, freeing up additional SKU space, providing more
specification flexibility, ease of installation and whisper quiet operation. A
factory supplied AAA alkaline battery provides up to two years of program
protection and time keeping without AC power. 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. Fits in a standard decorator plate; includes clear and color
matched faceplates.
