Ok, your setup has a few issues.

1. You need to get a thermostat for your UTH or unplug it. Without a thermostat controlling the UTH it will get way too hot (130 F+)

2. You need to get a different thermometer, the one you have isn't even telling you how hot your UTH is as UTH's only heats surfaces. You need a probed thermometer like this one:

3. Your cage temps are on the low side. The hot side needs to be between 88-92 F and the cool side between 78-82 F.
