Want to keep this simple. Installed the new RHP and can't keep the cool end below 79.5-80* without losing the right heat on the hot end (92-95*). I am using an on/off thermostat, but ordered a VE300 that will be here Monday. I have done so much to try and make this enclosure perfect, but I feel like the temps are off and my guy is staying on the cool side still. Will the VE300 be able to control anything more precisely? I realize the options for powering the RHP are different, which I think should help.
