I need a timer to turn a fan on and off at a pre determined interval. For example. I turn on the timer and it activates a fan. After lets say 20 minutes the fan turns off and then in 8 minutes it turns back on again. I need the cycle to repeat until I turn the unit off. The timing cycles I gave are only examples and will need to be adjustable as I don't know how long the fan will need to run until I start experimenting with it. I was looking in Grainger and found this. Does this do what I want it to do. The description of the device is vague. Or does someone else have another solution. Thanks.
