Power output on mypin pid

I have a mypin pid and I cannot figure out how to control the power output. On my boil kettle I want to maintain a rolling boil. I believe I need to adjust the power output on the element to around 80%.

Can someone help me?

 

Which one do you have

 

Mypin t4a

 

Ta4 doesnt not have the manual pwm mode capability... you need the TD4 model family for this (like the Td4-snr) .. sorry
if you had the td4 it would be as easy as holding the blue button down for 3 seconds till the green light comes on then setting your % value and hiting the yellow button to set it.

As a work around you can just set the temp to 213 degrees but you will get a 100% full power boil so if your element is very powerful for the amount your trying to brew this will cause a very vigorous boil with a lot of boiloff.
