Intermatic ST01/ST01k/EI600 Details

The Intermatic ST01/ST01k/EI600 digital timer offers robust scheduling capabilities, allowing for comprehensive 7-day programming. Users can define up to 40 unique event spaces, configuring combinations of "Dawn," "Dusk," or specific time-based schedules. An optional Automatic Daylight-Saving Time (DST) adjustment feature simplifies seasonal changes, eliminating manual adjustments. Furthermore, the timer supports three distinct languages: English (ENG), Spanish (SPAN), and French (FRN), enhancing its usability across a diverse user base. This versatility makes it suitable for a wide array of applications.

Beyond its scheduling prowess, the timer incorporates a practical "RAND" (random) feature. This mode intelligently varies switching times to simulate an "occupied" appearance, providing an effective deterrent against unwanted visitors when the premises are vacant. The device also boasts a flexible "DOWN" (countdown) function, enabling users to program automatic shut-off sequences ranging from a mere one second up to a full 24 hours after activation. This makes it ideal for managing power to various devices, offering both convenience and energy efficiency.

Powering the timer is a CR2 Lithium battery, which facilitates initial setup and programming without requiring AC power. The battery also maintains the internal clock and date, and controls the ON/OFF function, indicated by an audible "clicking" sound. A "BATT LOW" message on the display warns users when the battery charge is diminishing, prompting timely replacement. Crucially, all programmed settings—except for the current date and time during a brief battery change window—are retained in memory, even without continuous battery or AC power.

The user interface is designed for intuitive navigation. Menus "loop," repeating options for easy access, and dedicated "+" and "–" buttons allow for quick adjustments, with a hold function for faster scrolling. The "AUTO" and "RAND" operational modes become accessible only after at least one ON or OFF event has been successfully programmed, streamlining the initial setup process. For the countdown function, users can configure a 3-minute shut-off warning, known as "WARN," which can be set to flash the controlled lights as a visual alert or be turned off entirely.

Further enhancing its utility, the countdown function includes several "LOCK" options: None, Pause (disables the ability to suspend the countdown), Time (allows review but prevents alteration of the time setting), and All (locks both pause and time setting adjustments). Installation is straightforward; the timer is compatible with both single-pole and 3-way wiring configurations, and notably, it does not necessitate a neutral wire. For installations involving contractor or motor loads, the manual recommends incorporating an ET-NF noise filter to ensure stable operation and prevent potential interference.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Intermatic ST01/ST01k/EI600 Digital Timer, and we answer them below.


What types of loads can the ST01/ST01k/EI600 timer control?
It is compatible with incandescent, fluorescent, CFL, and LED lighting. It can also handle resistive (heater), motor, and DC loads within its specified ratings.

Is a neutral wire required for installation?
No, the Intermatic ST01/ST01k/EI600 Digital Timer does not require a neutral wire connection.

What languages does the timer support?
The timer supports three languages: English (ENG), Spanish (SPAN), and French (FRN).

How many events can I program into the timer?
The timer offers 40 available event spaces, allowing for various combinations of scheduled events, including Dawn, Dusk, or specific times.

What happens if the battery runs low?
If the battery strength is low, "BATT LOW" will flash on the display. It's crucial to replace the battery promptly to prevent potential timer damage from leakage.

Will I lose all my settings when replacing the battery?
When replacing the battery, you have a few minutes to insert a new one before the date and time settings are lost. All other programmed settings will remain in memory even without battery or AC power.

What is the 'RAND' (random) feature used for?
The RAND feature is designed to deter unwanted visitors by creating an "occupied" look through varied switching times when you are away.

How does the countdown function work?
The countdown (DOWN) function allows devices to be turned Off after activation, with durations ranging from one second up to 24 hours. It also includes an optional 3-minute shut-off warning.

Can I lock the countdown timer settings?
Yes, the countdown function offers several lock options: None, Pause (disables pause), Time (review but not change time setting), and All (locks both pause and setting changes).

The timer display is blank, or it doesn't 'click' when I try to turn it on/off. What should I do?
This typically indicates a missing, uncharged, or incorrectly installed battery. Install a new CR2 battery, ensuring it's properly seated with correct polarity.

The timer operates at incorrect times, or skips programmed events.
This could be due to conflicting or incorrect programmed events, a weak battery, or the timer being in RAND (random) mode, which intentionally varies switching times by up to +/- 15 minutes. Review your programmed events, replace the battery if low, or select "Auto Mode" if RAND is not desired.

My timer is acting erratically.
The operating software may have become confused and needs to be reset. Perform a "Factory Reset" by holding the ON/OFF button and pressing the RESET button with a paperclip or pen until "INIT" appears.

Can the timer be used in a 3-way wiring setup?
Yes, the timer supports both single-pole and 3-way wiring configurations. Ensure proper wiring according to the manual's instructions, especially regarding the remote switch and jumper wire.

What should I do if the timer is installed with a contactor or motor load and shows inconsistent operation (resets to 12:00)?
A noise filter (ET-NF) is recommended at the source of the noise when the timer is installed with a contactor or motor load to prevent erratic behavior.
