My room always stays between 68-70 degrees. Before I got a thermostat for the UTH, the substrate was 2-3 inches thick and it remained a perfect 90-95 degrees. No problems, but as soon as I put on the thermostat on, I'm lucky enough to get a 88 spike. It mainly ranges between 78-86 and I had to remove a lot of substrate to cover up the heat pad to an inch. On the cool side, I have a heat lamp that warms that side up to 80, rarely it gets up to 82/83.
I'm stressing with this thermostat. I know I shouldn't constantly check it but I have too for at times it doesn't get to where I feel comfortable that she's not getting the right heat. Things were so perfect without the thermostat... So I'm not sure what to do.
