Initial Setup
The following sections provide instructions for the initial setup of the time switch.
Setting The Output Configuration
The time switch output configuration enables users to control multiple loads simultaneously (SIM), independently (IND), or with a
2-second pulse (PUL). Output circuits are configured in pairs; circuits #1 and #2 first, followed by circuits #3 and #4.
In PUL mode, an ON event or manual override, causes circuit #1 to turn ON for two seconds, then OFF. An OFF event, or manual
override, causes circuit #2 to turn ON for two seconds, then OFF.
NOTE: The output configuration setup can only be accessed at initial startup of the unit or after a "Clearing Time Switch Memory"
operation. Follow this procedure to set the output configuration.
1.
Activate power to the time switch. The display shows IND, the ARROW icon above the ENTER/NEXT button and the LOAD
icons for circuit #1 and circuit #2 turn on.
NOTE: If the display does not show IND the output configuration is already set and a "Clearing Time Switch Memory" operation
must be performed.
2.
Press + or - to scroll to the desired output configuration.
3.
Press ENTER/NEXT to save the setting for the first two circuits.
4.
The display now shows IND, the ARROW icon above the ENTER/NEXT button and the LOAD icons for circuit #3 and circuit #4
turn on.
5.
Press + or - to scroll to the desired output configuration.
6.
Press ENTER/NEXT to save the setting for the last two circuits.
7.
The output configuration is now completed.
Programming Overview
The steps to program the time switch include setting the current date, time, Astro zone, Astro events, fixed events, DST, and Holiday
events, setting the time switch's operation to AUTO mode, ENERGY SAVER mode or MANUAL mode (only MANUAL mode will
appear if there are no scheduled events) and read or write an event schedule from a USB memory stick.
NOTE: If the time switch is left inactive for five minutes in a programming mode, it will return to the AUTO mode screen (AUTO icon
turned on). If no scheduled events are programmed, the time switch will return to MANUAL mode. If the date has not yet been
