When growing autos in a 2'x4'x6.5' grow tent using a mars hydro TS 3000 what should I adjust my I/O and V/O ports to for proper growth?

I adjust the V/O to about 55% I left I/O at 100%. That is the only way I could accurately control temp. Any higher and my tent would hit 85⁰ to 95⁰. I maintain a range from 73⁰ night - 77 - 81⁰ day. ( going on 3rd week of grow)

Hmmm a TS3000 doesn't physically fit in a 2x4 grow tent. Can you clarify? Also, what do you mean by I/O and V/O ?

Good afternoon, I am very new to growing and I purchased a tent and light from a hydroponics store I asked him for a good light and he gave me the ts3000 and said it work work good in my tent. On the two mean well drivers which is located outside of my tent have two little ports on each for dimming. One port is labeled v/o and the second one is labeled i/o. Im assuming that the v/o is voltage output which is set to about 55% and im thinking that the i/o is for intensity which i have set to about 95% . My plants just hit the 3rd week of grow and they are looking good as far as I can tell.

@JO521 Ok I understand what you mean by I/O and V/O now. Maybe someone that has grown with that LED grow light will reply with advice. Also, I did a few PAR tests with the TS3000 which may help you determine light distance. Here they are:
