If you connect Red and Blue wires together, the programming works in reverse: so when timer turns on, lights go off; when timer turns off, lights go on.

How to wire ST01C & EJ500 These instructions are for replacing ordinary light switch that has 2 wires.
Red wire is only used in 3-way circuit ... if your lights click on-and-off after installing ST01C or EJ500, you connected red wire where blue wire should go, so change them. Put wire nut over end of red wire so it is capped off.

1) Black wire from timer connects to Hot wire from breaker box
2) Blue wire from timer connects to Load (lights, fan, motor)
3) How to test for Hot and Load wires: Switch you are replacing has 2 wires. One wire is Hot. Other wire goes to Load. Disconnect wires from switch. Turn on power. Use ordinary tester, test each wire to bare copper wire. When tester lights up, that is Hot wire. The Hot wire connects to Black wire on timer. The other wire connects to Blue wire.

	3-way switch located on right, reverses operation of timer on left. When red and blue timer wires are connected, they reverse on-off operation of timer.

	Typical 3-way switching, with 4-way switch circuit
	ST01C or EJ500 inserted into 3-way/4-way circuit ST01C/EJ500 cannot replace 3-way switch 1-for-1 ST01C/EJ500 cannot replace 4-way switch 1-for1 Circuit needs extra wire going to 3-way switch (represented by blue wire) Blue wire must always go to Load (light, fan, etc) Black wire must always go to Hot Red wire feeds back, and reverses timer

ST01C uses one CR2 battery When exposed to freezing temperatures, battery will last 20 days.	EJ500 takes two LR44/SR44 batteries
