Hey bro, just stumbling through posts and thought I’d share... I too have the AC infinity cloud line, 6” model, comes with a digital controller and probe, does yours?
The smart mode is great. Set fan to max (6 bar) on on mode, then go to smart mode and set desired temp you don’t want to go over. For every 2c it goes down it drops a fan level. I have other problems right now, quite the opposite, too much heat haha. But maybe that will help you out.
During the cold I used a ceramic fan heater on an ink bird controller, was very nervous about it but worked out great. I was in a 2x4.
@Olderfart , are you by chance Archie? If you are you in fact gave me the advice a few years back on the heater if I remember rightly. Good stuff
