Manually set power control dial from 5 to 100% to control the output wattage
This timed control turns the output load on and off and then repeats the cycle. Each position on the knob from LO to HI represents a specific cycle time where the on time ranges from 6 to 100 percent. For example the LO setting represents a total cycle of 60 seconds with an on time of 4 seconds. This type of control can be used to regulate the temperature of resistive loads. The pilot light on the front will glow when the load is on.
