Programming Overview
By pressing the MODE button, the Time Switch will cycle through the
menus necessary for programming the current time, date, and timed
events.
The basic procedure is to use the MODE button to move from one
menu to the next (e.g., DATE, TIME, etc.), the + or – buttons for the
rst part of a setting (e.g., MONTH), the ENTER button to move to the
next part of the setting (e.g., YEAR), then MODE to exit and move to
the next menu. To skip a menu, press MODE to move ahead.
If you make a mistake, press the MODE button repeatedly to
cycle back around to the error, then make the correct entry.
NOTE: DATE and TIME must be set before you can access any
other programming menus.
Setting Date
1. Press the MODE button repeatedly until the words SET and
DATE appear in the upper area of the display.
2. Press the + or – buttons to enter the current Month.
3. Press the ENTER button when the Month is correct to save the
setting. The screen advances to current Date.
4. Again press the + or – buttons to enter the current Date,
followed by the ENTER button.
5. Repeat to set the correct Year.
6. Press the MODE button to exit and advance to setting the time.
Wiring Diagrams
9. Insert the wire ends under the proper terminal plates (see
wiring diagrams elsewhere on this page) and tighten the
screws rmly.
10. Connect ground wire to grounding terminal at bottom of enclosure.
11. Replace the plastic insulator on the retaining post.
12. Remove the battery case by sliding it down as shown by the
arrows, then install 2 AAA alkaline batteries. Make sure the
batteries are pointing in the direction shown.
13. Verify that the display is ON to make sure the batteries are OK.
If the display shows scrambled information, press the RESET
button to clear it up.
14. Apply power to the Time Switch.
IMPORTANT: Press and hold the ENTER button, then press the
RESET button. The screen will ash 12:00 AM, and timer status
is Manual Mode.
NOTE: You must reset the time switch using this procedure
whenever you change the jumpers.
The Time Switch is now ready for programming.
5. Mount the enclosure in the desired location using the 3 mounting
holes provided.
Position at eye level if possible, providing space to the left of the
enclosure for the cover to swing open fully, as shown.
6. Replace the mechanism in the enclosure.
7. Lift the left side of the plastic insulator off the retaining post and
pivot it up and away to expose the terminal strip.
8. Strip the supply and load wires to 1/2”. Use #18 -
#10 AWG wires, rated at least 75°C - COPPER
conductors ONLY.
