500w finnex dc8 recommended outlet ??

[JS_racer]

setting up my new to me classics, 500w finnex, is outlet 4 or 8 mandatory, or recommended ?? or will any outlet work. thanks.
dc8-finnex controller-500w heater tube is how i will have it, temp controlled by the apex, with the finnex as a safety shutoff

my second heater is a 300w, set a few tenths lower, guessing thats good for any outlet ??
wow, what a big learning curve from my old school aquacontroller jr, lol

thanks so much for the time

Any will work but 4 and 8 are recommended bc higher amperage.

I am running mine in 4 and 8. If you chose other ports you may burned them over period of time.
