PRODUCT DESCRIPTION
The ST01 and EI600 series timers combine scheduling, and countdown features into one simple-to-install unit. Features include 7-day programming with optional Automatic DaylightSaving Time (DST) adjustment, 40 available event spaces for building any combination of scheduled events (Dawn, Dusk or Specific times), RAND (random) feature used to deter unwanted visitors, providing an “occupied” look when you’re away, and more. The DOWN (countdown) function is designed for turning devices Off after activation, ranging from one second up to 24 hours, and is incandescent, fluorescent, CFL and LED compatible. The ST01/EI600 can handle most load types, does not require a neutral wire connection, and supports three languages, English (ENG), Spanish (SPAN), and French (FRN), making it ideal for many applications.
IMPORTANT NOTES
Please read these notes before continuing. · The timer is battery-powered and does not need AC power
for initial setup and programming; it also controls the ON/OFF function (“clicking” sound) and maintains the time and date. · BATT LOW flashes on display when the battery strength is low. · When replacing the battery, first disconnect the AC power. Once the old battery is removed, you’ll have a few minutes to insert the new battery before the date and time settings are lost. All other settings will remain in memory, without battery or AC power. · AUTO (automatic) and RAND (random) modes don’t appear in the menu options until at least one ON or OFF event is programmed. · All menus “loop” (repeat options at end of menu). When in a specific MENU, press ON/OFF to loop within that MENU. · The + or – buttons change what is flashing on the screen. Hold them down to scroll faster. · Countdown (DOWN) function allows users to decide between setting a 3-minute shut-off warning WARN (warning) or turning WARN (warning) off.

Before programming, install the supplied battery. · Gently pry open the access door, located below ON/OFF
button, and remove the battery tray from the timer. (Search for YouTube video for “ST01 Programmable Timer Battery Replacement”) · Place the supplied CR2 battery into the tray. Make sure to match the + and – markings on the battery to the tray. Install the tray into the timer. · The product initializes and enters the MAN (manual) MODE of operation with the time blinking at 12:00 am Note: If the display does not flash 12:00 am, check/replace
the battery before proceeding.

INSTALLATION

PRO-TIP: When installing a timer with either a contractor

or motor load, a noise filter is recommended (ET-NF). An

example of single-pole and three-way wiring follow. For other

three-way wiring scenarios, go to www. intermatic.com.

7/16″

Disconnect the power at the service panel.

1. Remove wall switches, if applicable.

2. Strip the existing wire ends to 7/16″.

3. Wire the timer into the wall box.

C Red — Connect to the remaining wire removed from the switch being replaced. Record the wire color connected to the red wire for use during load-side installation
D Green — Connect to the supplied ground
E Jumper Wire — At the other three-way switch, install the supplied jumper wire between wire B and the common terminal

FINALIZING INSTALLATION
1. Make sure the provided twist-on wire nuts are secure, then tuck the wires into the timer wall box, leaving room for the timer.
2. Using the provided screws, secure the timer to the wall box.
3. Cover the timer with the wall plate and secure using the provided screws.
4. For three-way wiring, install the remote switch in wall box. 5. Install the wall plate and secure. 6. Reconnect the power at the service panel. Testing the Timer Make sure the timer displays MAN (manual) MODE during testing Single-Pole Wiring Test To test the timer, press ON/OFF several times. The timer should “click” and the Controlled light or device (load) should turn ON or OFF. Three-Way Wiring Test 1. To test the timer, test with the remote switch in each of its
two positions. 2. Press ON/OFF several times. The timer should “click” and
the controlled light or device (load) should turn ON or OFF. 3. If the timer clicks, but the load does not operate:
a. Disconnect the power at the service panel. b. Re-check wiring and make sure the load is functional. c. Reconnect the power at the service panel. d. Retest. 4. If timer clicks, but the load only operates when the remote switch is in one of its two positions, repeat Step 3, a-d, but interchange the two traveler wires (wires Between the timer and the remote three-way switch) connected to red and blue timer wires PRO-TIP: Consult a qualified electrician if the switch and
timer fail to operate as intended 5. When the timer “clicks” and the controlled device turns
ON and OFF as programmed, the timer is successfully installed!
