IF YOU FOLLOW THE INSTRUCTIONS FOR THIS PROGRAMMING IT WILL DRIVE CRAZY! THIS IS A GREAT PRODUCT FOR SWITCHING DEVICES ON AND OFF, ALSO FOR FIRMWARE OR MANY OTHER THINGS. I BOUGHT IT FOR A SIMPLE WORK 0.5 SECONDS ON AND 150 SECONDS OFF THEN REPEAT BOY WHAT EDUCATION I FINALLY UNDERSTAND THIS AFTER WATCHING A VIDEO ON YOUTUBE AND READING THE BIG INSTRUCTIONS. IF YOU ARE A PROGRAMMER YOU WILL NOT HAVE A PROBLEM I THINK. I UNDERSTAND THAT IF I WANTED THE TIME TO TURN ON (OR 5 SECONDS) I MUST TOUCH THE T-1 TO THE GROUND BUT WHEN I WANTED A TIME DELAY THERE ARE NO INSTRUCTIONS WHAT TO DO. THE INSTRUCTIONS SAY TO TOUCH THE T-2 TO THE GROUND BUT IT DON'T SAY WHAT IT DOES. AFTER MANY HOURS OF TRYING AND ERROR, I UNDERSTAND THAT THE TOUCHING OF THE T-2 TO THE GROUND IS THE SHUTDOWN TIME INTERVAL AND WHEN YOU KEEP IT AT 150 IN A PROGRAM THE DURATION OF STILL TIME I WAS SEARCHING FOR. BUT, THIS DOES NOT TELL YOU THAT THE LIGHT IS ON WHILE YOU PROGRAM THE OFF TIME. THIS HAS JUMPED ME INTO A LOOP JUST SIMPLE INSTRUCTIONS LIKE T-1 ON TIME FOR THE DESIRED SECONDS OR MINUTES AND T-2 THIS IS THE LENGTH OF THE OFF TIME BUT THE LIGHT IS TURNED ON TO KNOW THIS IS THE SETTING OF YOUR OFF -TIME IS . YOUR HELP LINE DID NOT HELP ALSO, YOUR ANSWER WAS TO WATCH THE VIDEO AND READ THE INSTRUCTIONS. I BET ANYONE CAN SET THE TIME AND DURATION NOW LIKE I DID THIS EASY INSTRUCTION. YOU MUST MOVE THE FUNCTION TO 5 TO REPEAT THE CYCLE, AND EVEN IF THE INSTRUCTIONS DO NOT TELL YOU (DO NOT TURN THE POWER OFF UNTIL THE FUNCTION HAS SET), AND SETTING THE FUNCTION WILL TURN THE LIGHTS DURING T-1 AND T SWITCH OFF -2 EARTHED AT THE SAME TIME BUT THAT LIGHT WILL TURN ON WHEN WIRES ARE REMOVED TO GO TO NEXT FUNCTION. AFTER THE TRANSACTION, YOU MUST DISCONNECT THE POWER TO LOCK THE SETTINGS. THEN CHECK IF THEY ARE SET, I WAS AMAZED THAT THE TIMER WAS ON FOR 5 SECONDS AND SWITCHED OFF FOR 150 SECONDS AND REPEATED, AFTER SWITCHING OFF THE SETTING WILL NOT CHANGED UNLESS YOU REPROGRAM IT. THE USE FOR THIS FOR ME WAS TO REPLACE A SET OF POINTS IN AN ANTIQUE CLOCK THAT PULSE TO EARTH ABOUT EVERY 150 SECONDS SO I GROUNDED THE POINTS AND DRIVEN WITH THIS TIMER WHICH WORKS PERFECTLY NOW.
