Description
This document explains the setup and configuration of the Intermatic ET8415 4-Circuit Electronic Astronomic 7-Day Time Switch. The ET8415 time switch automatically switches loads to a preset weekly schedule. The time switch can support up to 28 fixed ON and 28 fixed OFF events (56 total) and up to four Astro events. Each event can be applied to any combination of circuits and days.
The time switch features an LCD and panel-mounted control buttons to set, review, and monitor the time switch functions, including enabling or disabling Daylight Saving Time (DST) and configuring DST switchover dates. Follow these instructions to complete the installation and programming for the ET8415 time switch.

Installation
WARNING Risk of Fire or Electric Shock
•Disconnect all power before installing the time switch or connected loads.
•Follow local electrical and safety codes, National Electric Code (NEC) and Occupational Safety and Health Act Codes (OSHA).
•More than one disconnect or circuit breaker may need to be turned off to de-energize all conductors.
•If the power disconnect point is out of sight, lock it in the OFF position and tag it to prevent unexpected application of power.
•The time switch must be grounded.
•Do not exceed maximum current carrying capacity.
•Always replace the plastic insulator to its original position before powering the time switch.
•Make sure there is no wire insulation under the terminal plate on time switch connector. Firmly tighten terminal screws.
NOTICE
Do not touch the circuit board components. Contact with the circuit board components can create static discharge, which can damage the microprocessor.
Follow these instructions to install the time switch. |

Programming Overview
Press MODE to scroll through the menus and program the current date, time, Astro zone, Astro events, and fixed events.
Press + or - to configure the first part of a setting, such as MONTH. Press the ENTER/NEXT button to move to the next part of the setting, such as YEAR, and then press MODE to exit and move to the next menu. Press MODE to skip a menu, correct an entry, and scroll back to an error, and adjust.
NOTE: If the time switch is left inactive for five minutes in a programming mode, it will return to the time of day screen. If no events are programmed, the time switch will return to manual mode.
Initial Setup
The following sections provide instructions for the initial setup of the time switch.
Setting The Operational Mode
The time switch operational modes enable users to control multiple loads simultaneously (SIM), independently (IND), or with a 2-second pulse (PUL). In PUL mode an ON event or manual override causes the first circuit to turn ON for two seconds, then OFF. An OFF event or manual override causes the second circuit to turn ON for two seconds, then OFF. Loads 1 and 2 and 3 and 4 can be set to different operational modes.
NOTE: The operational modes can only be accessed at initial startup of the unit or after the unit memory is cleared.
Follow this procedure to set the operational mode(s).
1.Activate power to the time switch. The screen displays ENTER/NEXT.
2.Press + or - to scroll to the desired operational mode for loads 1 and 2.
3.Press ENTER/NEXT to scroll to the operational mode for loads 3 and 4.
NOTE: Operational Mode is set according to load pair. Set the operational mode for loads 1 and 2 first, then loads 3 and 4.
4.Press ENTER/NEXT to save the setting.
Setting Date and Time
Follow this procedure below to set the date and time in the time switch.
NOTE: If necessary, hold + or - to scroll through the digits rapidly.
1.Press MODE to scroll through the menus until SET and DATE appear at the top of the display. The month flashes.
2.Press + or - to select the current month and then press ENTER/NEXT. The day of the month flashes.
3.Press + or - to select the current day of the month, and then press ENTER/NEXT. The year flashes.
4.Press + or - to enter the current year, and press ENTER/NEXT.
5.Press MODE to advance to the set clock screen. A flashing 12:00 appears.
6.Press + or - to enter the current time and press MODE to save and exit.
