7 Day, 15 Amp

This series provides photo control initiated / time switch terminated control. These time switches provide a different “ON/OFF” program each day of the week and a spring wound carryover. These time switches are recommended for applications where you need to turn a load “ON” at dusk and “OFF” at a preset time. The spring wound carryover provides a carryover of 16 hours minimum to maintain accurate load control even during power failure. When power resumes, the carryover automatically rewinds itself. Only 1 hour is required to rewind the carryover for each 2 hours of outage. The three models provide control of 1, 2 or 3 circuits. A light level adjustment is provided on the photo control. All models have single pole double throw switches and manual circuit by-pass switches.

Unit is designed to control the contactor control circuit only. It is not recommended for direct switching of tungsten, mercury vapor or similar loads.
