APPLICATION

The ST7009 family of one and two-switch Programmable Timers are
compact time controls providing 24-hour or 7-day microprocessor­based switching. Heavy duty 16A spdt relay contacts can switch low­or line-voltage loads. Up to 21 on and 21 off functions are available
per day .

These timers are applicable for time-of-day control of pumps, fans,
heaters, HVAC control circuits, lighting and many other types of
commercial and industrial equipment.

• Screw wiring terminals.

All models feature large keys and a large LCD display for easy circular
programming of schedules. The ST7009 allows for selection of any
combination of days and additional programming events per day.

Built-in program backup provides retention of memory and time of
day during a power outage. The ST7009 features an automatic
internal recharging battery backup program for up to a two-week
period. The ST7009 also offers a holiday programming schedule of
one or more days that can be programmed up to a week in advance.
