I am experiencing difficulty setting a "Click 24/7 Digital Timer". I want it to start 5:00 pm each day and off at 5:03 pm.
It will turn on a pump attached to a water tank and deliver water right round our gardens front and back. I have had it operating for over ten years and it worked wonderfully well until the timer packed up. I have a new timer and cannot set it up correctly. I have taken it with the instructions back to my local Bunnings and requested assistance on three separate occasions. Each time I have taken it home it did not work. The last time was this morning and mid afternoon I discovered my garden well watered, no water in the tank and pump still running and two hours before it should start up.
I now know I should have set it up inside the house on a lamp instead of the pump.
Any suggestions would be most welcome.
