Intermatic ET70115C electronic energy control timer
These electronic time switches provide to-the-minute programming for 7-day or full year load control and reduced energy costs. A user selectable clock format for 12 hour AM/PM or 24 hour is provided. Full year control features include up to 99 different "holidays" each of which can be programmed for any duration. Any holiday or holiday duration can be left for "no load activity" or programmed for a unique load activity. Fully automatic daylight saving time adjustment, with user selectable override, and automatic leap year adjustment are also standard on the ET70000C series. Weekly programming provides single step weekday and weekend programming to simplify typical 5/2 day load control. An automatic review feature enables quick easy review of all programmed data.
Flexible load control is enhanced by Astro, Pulse and Interval options as required for outdoor lighting control, bell ringing and after hours temporary override respectively. These options can be combined, for example, to provide Astro switching with a Pulse output for outdoor lighting using a latching contactor. Each of these options is selected and programmed by the installer using a unique "self-prompting" display with LED indicators dedicated to each option.
A 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 calender information for a minimum of 8 years. The self contained logic board is shielded and utilizes advanced circuit board layout techniques and state of the art micro components to eliminate problems related to electrical noise interference. Transient protection for up to 6,000 volts is provided by the power board. These time switches are housed in a lockable steel enclosure. Both NEMA 1 and NEMA 3R enclosures are available for the 1 and 2 circuit models which also fit all standard Intermatic T100 series enclosures.The 4, 8 and 16 circuit models are standard in a NEMA 3R enclosure
