Model Number: ET70115CR24
Next Generation Time Switches
These electronic time switches provide to-the-minute programming for 7-day or full year load control. Features: 12/24 Hr clock format, 99 holiday schedules, and auto daylight savings time adjustment. 1, 2, and 4 circuit models feature 1,000+ ON/OFF events; 8 and 16 circuit models feature 4,000+ ON/OFF events. Flexible load control is enhanced by Astro, Variable Pulse, and Interval options as required for outdoor lighting control, bell ringing and after hour temporary override respectively. Non-volatile memory maintains all programmed switching times for the life of the time switch. A factory installed field replaceable lithium battery maintains accurate time keeping and calendar information for a minimum of 8 years.
