Ok finally got it all set up today, interesting system that's for sure.
I had some issues but after looking online it seems like the 1/4 model (maybe others also) show 1 degree off, So 79 really means its at 80.
It also only kicks in when its 2 degree difference from what you want it at, ( if you have it set at 77 it will turn on when it hits 79). Saw online someone say its so its not always running just to set my temp 1 degree lower and it will balance out (So if you want 77 set it to 76).
I have it using the pump from the right chamber in my tank right now but im unsure if that's strong enough ( still trying to figure that one out).
In the end its working and doing what I need it to, and when its on I have no clue! (I have heard it though at one point to make sure it was not broken).
That's my little update!
