Thermostats

I know I've been asking a lot of questions, but here goes.

My thermostat is working wonderfully, but the only problem is that I'm having to daily adjust the temperature to keep it at 90-91 degrees, and I'm wondering if this is normal, and If it is not what I can maybe do to fix it?

I'm using an UTH and the Zilla Thermostat.

Thanks so much!! :)

UTH's have some variability in thermal distribution, a 1 degree variation is easily within specification. I wouldn't bother adjusting for a single degree-your pet won't know the difference.

I am guessing it is the analog dial type they sell? This is an on/off style with a dial to guesstimate the temp. The on off nature of these style of thermostats means it will shut off once it gets to temp and not come back on until the probe measures a certain temp. This causes a fluctuation in the temp of the UTH as it heats then shuts off and cools.

It's not a bad thing as long as you keep close to a desired temperature. Now if it varied say 20 degrees that would be an issue but a few degrees swing is nothing.

If however your OCD gets the best of you and you need constant temps, you need to spend the money and get a proportional style thermostat that will send micro pulses of electricity to the heating element to keep it more steady with the range you want.

So it is normal with low cost thermostats and not a problem as long as the range is just a small degree swing difference.

It is really warm in the day time (my house too) and then gets pretty cool at night and so that when I usually have to adjust the temp like, lower it in the day and raise it in at night... I'm just wondering If It's normal to have to do that? Or is it okay to have her hot spot cooler at night maybe?

Do you have an infrared heat gun? And where are you taking the temps for the uth and how are you taking the temp?

Yes, I have an infrared temperature gun.

You will have to buy a different/better thermostat if you want to adjust the heat settings for different times of the day.

Would it be fine for her to have a cooler hot spot at night?

Temperatures naturally drop at night anyway so if yours moves a few degrees it's no big deal.

Would 85 be fine at night?
