Product Description

The ET170 series electronic time switches provide to-the-minute programming for accurate load control and reduced energy costs. All programming and clock setting is accomplished with the use of two slide switches and five push-buttons. Up to 20 set points (10 ON/10 OFF) can be preset to automatically repeat on a weekly or daily basis.

These time switches provide true 7-day load control with up to 140 operations (70 ON/70 OFF) each week. A manual override switch allows the program to be overridden if required.

The time switch shall be a solid state electronic control capable of permitting 20 ON/OFF set points to be distributed on independent daily schedules through a 7-day time period. The time switch shall include a 7-day repeat feature for simplifying programming of identical set points. The time and set points shall be programmable to the nearest minute with a minimum ON duration of 1 minute and a maximum ON duration of 6 days, 23 hours, 59 minutes. The timer shall have a digital LCD readout to show day of week and time-of-day using 12 hour AM/PM indicator. The time switch shall provide a manual override control for both temporary or permanent override. Time switch shall operate over a temperature range of -40°F (-40°C) to 155°F (58°C). An industrial grade AA alkaline battery shall protect program information and time-of-day for a minimum of 3 years.
