Question about Intermatic Inc. ST01C Digital In-Wall Timer
The ge 15312 is on the load side and the jumper wire was installed on the line side
GE 15312 sunsmart can be wired for single-pole or 3-way.
One 3-way switch is replaced. The other 3-way switch remains and is re-wired slightly so that timer programming can be reversed.
Copy following link to double-check wiring is correct:
Scroll down and look at each of the three 3-way illustration, Line side, load side, without neutral.
Here's how the timer works for 3-way:
When the red wire receives power, it reverses the timer programming of on-becomes-off or off-becomes-on.
So the purpose of the remaining 3-way switch is to connect-or-disconnect power to timer red wire >> this causes the 3-way effect.
Basically the remaining 3-way switch is converted into a simple on-off switch by using only one of the brass screws, and the dark screw.
So one of the brass screws on the remaining 3-way switch has no wire connected to it. It makes no difference which of the two brass screws is selected.
Add a comment as needed.
This timer has 1 year limited warranty through jasco, or just buy another one from Home Depot and return defect in new package.
