365/24-Hour Electronic Control
The ET2100 Series 365/24-Hour Electronic Controls feature 24-hour
programming. Up to 48 ON and 48 OFF events can be preset to
automatically repeat, and can handle complex 24-hour schedules.
These electronic controls provide dependable and uncomplicated
performance, plus to-the-minute programming for accurate load
control and reduced energy costs. Each event can be applied to any
combination of circuits. In addition, the programming can be easily
disabled by changing to the manual operating mode. An additional
mode of operation allows for the ON/OFF buttons to be used as a
2-hour override, in compliance with current regulations. Manual circuit
control buttons operate circuits independently, based on the mode of
operation. 50 Holiday Block Scheduling exception dates are available
to prevent regularly scheduled events, or allow for a holiday schedule.
All models come equipped with a time and date retaining
supercapacitor for a minimum of 100 hours, eliminating battery
dependency. Each electronic control is housed in a lockable
enclosure for vandalism and tampering protection
