Jasco Products Company, LLC GE 15312 SunSmart In-Wall Self-Adjusting Digital Timer GE 15312 3-Way Astro In-Wall Digital Timer. Feb 05, 2012 I am trying to install a GE SunSmart Digital Timer (3-way) into an existing circuit. The existing circuit, on the 3-way switch that I removed, has white, red, black and green wires. When I hook up the timer the timer comes to life but the load will not come on.
The GE SunSmart Seven-Day Two-Outlet Digital Timer can control up to two lamps or devices using preset or custom settings for each day of the week. The timer can also be used for seasonal lighting, small appliances or electronics. It features a seven-day programmable timer, random vacation setting and is programmable to the exact minute. In the event of a power failure, a properly charged timer will retain programming for an estimated three months.
Initial Set Up
- Plug the timer into a standard 125 VAC 60 Hz household electrical outlet.
- Use a paper clip or ball point pen to push the 'RESET” button, located directly below the 'HOUR' button. All elements of the display will light briefly, then display a default time.
- Press the 'CLOCK' button and hold while pressing the 'HOUR', 'MIN' and 'DAY' buttons individually to set the correct day and time. When finished, release the 'CLOCK' button to save programming.
On / Off Timer Programming
- Press the 'SET' button once. The timer should display the days of the week and '1 ON --:--' to indicate that you are accessing the first timer program. The timer will save up to 20 ON / OFF programs.
- Press the 'HOUR' and 'MIN' buttons to select the ON time. Press the 'DAY' button to select the appropriate days of operation. Press the 'SET' button again to confirm and save the programming. The display will change to '1 OFF --:--'.
- Press the 'HOUR' and 'MIN' buttons to select the OFF time. Press the 'DAY' button to select the appropriate days of operation. Press the 'SET' button again to confirm and save the programming.
- Repeat the process to access the remaining timer programs. These programs can be used to program different timers for each day or multiple timers in a single day.
Random ON/OFF Setting and Daylight Savings Time
- Press the 'HOUR' button and hold for three seconds. The display will show 'RND'. This feature will randomly alter your programmed settings by +/- 30 minutes to simulate an occupied home.
- Press the 'HOUR' button and hold for three seconds to deactivate the random feature. The 'RND' display should disappear.
- Press the “CLOCK” button and hold for three seconds to advance the current time one hour. The display should show '+1h'. Press the 'CLOCK' button again and hold for three seconds to decrease the time by one hour. The '+1h' icon will disappear.
Countdown Timer
- Press the “SET” button repeatedly until the 'CTD' icon appears. This will appear after the ON / OFF program.
- Press the “HOUR” and “MIN” buttons to set the amount of ON time before the timer switches OFF. Press the “CLOCK” button to save programming and return to the main display.
- Press the “HOUR” and “MIN” buttons simultaneously to start the countdown feature. To deactivate, press the 'HOUR' and 'MIN' buttons simultaneously again.
Tip
If the timer screen displays numbers, programming can be completed before plugging it into a power outlet. Timer must be in the “Auto On” or “Auto Off” mode to use programmed settings. The timer is capable of multiple day combinations such as Monday through Friday or Tuesday and Wednesday. This option is presented during the ON / OFF timer programming process.
