Thats how it works. It doesn't change the line voltage if that is what you are thinking.
In the configs t is the cycle time. Which is defaulted to 2 seconds.
This sets the 100% duty cycle. so if you change the manual output to 10% the element will turn on for .2 sec and stay off for 1.8s.
If you are using an SSR you can set it to 0 which is .5s. The pulses will be much quicker.
