those UTH are NOT meant to be removed. if you read the instructions you would have known this. you have probably damaged the internals and it is most likely very dangerous. there is absolutely no reason to ever remove it "because it's daytime." a thermoSTAT will regulate the temp thus making removal unnecessary. get a new UTH, get a THERMOSTAT like NOW, and use it.
throw away that analog thermometer. it is worthless in terms of accuracy. also i don't see how you're measuring humidity. get a digital thermometer/hygrometer combo for $10 at walmart.
ditch the bulbs. light stresses beeps out. get a CHE (ceramic heat emitter) instead with a ceramic socket.
that water dish is ENTIRELY too small. the animal should be able to fit in it.
you have a hide that's open on both sides, and only one. two identical cave-like hides is standard. that hide is no where near secure enough, hence why you never see him use it.
stop saying "that's what they told me." you need to do your OWN research and actually LEARN about your new pet. we're trying to help but only you can decide to research and seek out the knowledge. this should have been done before bringing an animal you don't know how to care for home. not trying to be harsh, but we see so many noobies maim and almost kill their pets from their ignorance EVERY year.
PLEASE go to the husbandry section on the forum and read ALL the stickied threads (on mobile can someone send the link)?
good luck.
