Here's how to set Woods TD1000 timer

This is older timer with backup battery. Plug in timer to see if battery will recharge. Display shows when battery is charged. No display, then timer is no good.

TD-1000 timer has 8 on-off functions per 24-hour day ...newer timers offer 7 day function with more programming choices... which may explain why TD1000 instructions are hard to find

Timer has 5 buttons + reset:
TIME MODE PROG HOUR MIN

Set time
Press and hold TIME > use Hour to set hour, Min to set minute
Release Time button ... correct time should show

Program: Capacity for 8 on-off times per day
Press PROG to set first ON time
ON and number 1 are displayed on left
Use hour and minute button to set ON time

Press PROG to confirm
Now, OFF and number 1 are displayed
Use hour and min key to set OFF time

Press PROG to confirm

When 8 programs are set, Press MODE key.
Choose Manual OFF. Manual ON, Auto ON, Auto Off

To use programs, select Auto ON

DST daylight savings time has to be done manually.
Press HOUR MIN button simultaneously > timer set up one hour
Repeat again and timer goes back one hour

Do not plug timer into extension cord > must be plugged into wall
