Identify wire that connects to common screw
Usually the dark-colored screw
1) Take photo of wires before disconnecting old switch.
2) Note which wire connects to dark-colored screw
3) If screws are not color-coded: Look on back of old switch to see which screw is marked common, and then mark that wire as common.

With timer on Load side: if electricity goes OFF, then timer will start to click on-off using the battery. If this happens, click the 3-way switch up or down. Afterwards, the timer will no longer click on-off.

If power remains off for a while, the current time must be re-programmed. However the scheduled programs are not affected by power outage and remain in memory forever until timer is manually reset.
3-way / Timer on Load side
Timer on Load side
Blue wire connects to wire that was connected to common screw
Timer black wire must always be connected to Hot
Blue wire must always go to Load
When power is applied to red wire, the timer programming reverses.

Remember, the remaining 3-way switch has to be rewired as if it was ordinary on-off switch using common screw and one traveller screw.
When the switch is turned ON-OFF, it reverses timer programming.
