PRODUCT DESCRIPTION

The ST01 Series and EI600 Series In-Wall Timers  give you versatility in a simple to install, 24/7 programmable package. These timers allow you to customize your timer schedule with automatic dusk/ dawn, random, and Daylight Saving Time (DST) programming options for up to 40 ON/OFF events. The ST01 Series and EI600 Series are incandescent/ fluorescent/CFL/LED compatible. In addition, these timers can handle any load type and require no neutral wire connection, making them ideal for any application, regardless of complexity.

TIMER INTERFACE

PRE-INSTALLATION

Before mounting the timer in the wall, install the supplied battery.

1. Gently pry open the access door, located below ON/OFF, and remove the battery tray from the timer.
2. Place the supplied CR2 battery into the battery tray, matching the battery + and – markings to the + and – markings on the tray, then place the battery tray back in the timer.
3. The display initializes, then flashes 12:00 am in manual mode.
4. Press ON/OFF. The timer “clicks” to confirm it is ready for programming.
   Note: If the display doesn’t flash 12:00 am, check/replace the battery before proceeding.

NOTES
Read these notes before continuing with the timer installation and programming process.

• The timer is battery-powered and does not need AC power for initial setup and programming. For new installations, it is recommended that you setup and program your timer before installing it.
• The battery controls the ON/OFF function (“clicking” sound) and maintains the time and date. The screen flashes BATT when the battery strength is low. When replacing the battery, disconnect AC power. You will have a few minutes to insert new batteries before the date and time settings are lost. All other settings will remain in memory, without battery or AC power.
• Each ON or OFF setting is an event. Each event must be programmed separately.
• The MODE menu includes SETUP, PGM (program), AUTO (automatic), RAND (random), and MAN (manual). AUTO and RAND modes do not appear on the menu options until the time of day is set and at least one ON or OFF event is programmed.
• All menus loop (repeat options when you get to the end of the menu). When in a specific Mode, press ON/OFF to loop within that Mode.
• When using the + or – buttons to change a flashing setting, hold the button to make the numbers scroll faster.
• When advancing to the next setting, the timer automatically saves the data from the previous screen whether you changed a setting or not. All settings save automatically after five minutes.
