This timer is a cyclic timer with a fixed total ON / OFF period of 1 minute, 30 minutes or 1 hour. Three on-board jumpers can be used to limit the total ON / OFF period to 1 minute, 30 minutes or 1 hour. You can then set the ON period of the cycle using the variable resistor. For example, if you set the variable resistor to 1/3 of its range, the ON period will be about 20 minutes and the OFF period will be about 40 minutes (assuming the jumper is set to the 1-hour mode).
