How
to wire ST01C & EJ500 and Ei600 This
illustration is 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, you connected red wire where blue wire should go, so change them. Put wire connector over end of red wire so it is capped off. If you connect Red and Blue wires together, the programming works in reverse, and 'off' becomes 'on' and 'on' becomes '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 install. Single-pole switch has two wires. Connect one wire to Timer Black and one wire to Timer Blue. If timer does not work after installation, then swap black and blue wires. |

Use Intermatic ST01C ST01C is battery operated and does not need either Neutral or ground wires to operate light Connect Black to Hot wire from breaker Connect Blue to wire going to Load Cap off Red wire Connect green to ground wire if available If timer does not work after power is turned ON, try reversing Timer Black and Timer Blue wires |

Switch
installed in junction box. Junction box always has Neutral wire. Black hot wire enters junction box. Illustration shows both black wires connect to switch: Hot connects to switch, and Black going to next box connects to switch. Timer Black connects to Hot wire & other black wire Timer Blue connects to Load wire Timer Green to ground Timer Red is always capped with single-pole install |

ST01C rated for
incandescent, CFL, LED, halogen, motors, etc. Use ST01C to control 120Volt or 240Volt pump ST01C timer is rated for 15amp. Maximum 100' distance. Timer does not require neutral wire, so timer can control 240 Volt loads. 240Volt load can be controlled directly by timer, ot install contactor as shown. 240Volt circuit can be turned OFF by cutting one Hot line. Use illustrated wiring to control pumps or any large amp load that exceeds timer rating. Example definite purpose contactors Optional: Add 15 amp busman line fuse to protect timer if circuit breaker exceeds 20 amp. See illustration |

![]() Timer replaces one 3-way switch Other 3-way must be rewired |
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. Common wire will connect to Timer Black wire, or Timer Blue wire. |
||
![]() Larger image 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. |
ST01C
timer wired for 3-way 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. |

Timer
on Line side, same as illustration above Timer Black wire MUST be connected to Hot. Timer Blue wire MUST be connected to Load (light). When power is applied to red wire, the timer programming reverses. The blue wire must always go to Load, and the red wire is for reversing timer program. So the only purpose of the 2nd 3-way switch is to reverse and re-reverse timer program. Be sure to use dark-colored 'common' screw on 2nd 3-way switch as shown, and then use either of the other screws on the 2nd 3-way swtich. Aube timer can be used to replace either 3-way switch |

Identify
wires inside 3-way switch box 3-way switch box will have minimum 3 wires. Most 3-way boxes will have 5 wires. Other 3-way boxes can have 7 wires, or more depending on the number of junctions connected inside the box. Example shows typical 3-way switch box. Two cables enter the box. One cable has 3 wires plus ground Second cable has 2 wires plus ground |

Quick
note. Manual has
troubleshooting section. See
ST01C Manual The important thing to remember is that this timer will keep programming inside memory indefinitely until you use reset button. If timer is flashing 12:00 after replacing battery, then just set current time and then your old programs are still there. How to replace battery on ST01C timer / How to replace battery on Ei600 timer As last resort for malfunctioning timer, hold down ON-OFF button and press and release reset button. Keep holding ON-OFF button until INIT flashes on display. Release ON-OFF and 12:00 will start flashing. If resetting timer does not restore functionality, then timer has gone bad. ST01C and battery operated timers do not require electricity for display to show. This timer has 1 year limited warranty from Intermatic. Warranty claim |
Battery cannot be
exposed to freezing temps longer than 20 days
![]() Change CR2 battery
on ST01C
If
ST01C or EJ500 do not function correctly after battery change, then
re-set timer and see if 12:00 is flashing. Then reprogram timer.
