24-Hour Electronic Time Switch

The ET1100 24-Hour Electronic Time Switches enable a program to be
repeated on a daily basis. These time switches provide dependable and
uncomplicated performance, plus to-the-minute programming for
accurate load control and reduced energy costs. Up to 28 setpoints or
events can be preset to automatically repeat. The program can be
disabled at any time by placing the time switch in the Manual
operating mode. Control buttons provide manual control of each circuit
independently, regardless of the operating mode. All models come with
two industrial-grade AAA alkaline batteries to provide time keeping and
automatic carryover for a minimum of 3 years. The batteries are easily
replaced in the eld and do not require removing the time switch
mechanism or eld wiring. Each time switch is housed in a lockable
enclosure to protect against vandalism and unauthorized tampering.

Features

• Program can be repeated on a daily basis

• Multi-volt operation from 120-277 VAC, 50/60 Hz
