I did tell you the controllers gave bursts of energy see previous posts
If you are using it on 115 volts the controller should work ok for however long
but we use 230 here and all controllers failed after a short time (after changing the internal links)
I think the designers made them for 115 with 230 volts being an afterthought and no american designer can get their head around 50Hz as apposed to 60Hz so some cooked the internal small xformer primary because of the wrong core laminations --a design co%^-up
