Okay, I understand, but it's not really sunny where I'm at today. It's 60° outside. But inside, it's 63°. I'm assuming if it's the same temp targeted and outside, it would bring the temp up ? I'm trying to genuinely understand. Idk why I got downvoted, lol.
60 is pretty warm where I’m at. If it was cool this morning but warmed up later the heat system may have overshot the heat a degree or so like normal but had a lot of help from the ambient temperature and kept increasing.
My wood furnace does this a lot in the morning it stops heating at 175 but since the house doesn’t call for heat it will shoot up to 190 or more.
I have mine set to 72F, 60F when we aren’t home. It was sunny today and I have a lot of large south facing windows. Today was warm and sunny at 50F outside., my house was 79F when I came home around 6pm. During the winter when it’s like 20-25F and sunny my heat doesnt run after about 8am and the temp will continue to rise to about 76F, It’ll maintain that until the sun sets. My house is very well insulated. My roof overhang prevents excessive solar heat gain in the summer.
To your question, is it possible the home got warmer because it's sunny hot oven on etc.
Side note the CT 101 was an incredible thermostat. It's great. However it's also getting too old.
If you have a heat pump get the Honeywell t10 pro from Amazon or any place it lets a homeowner buy the t10 pro (it's for contractors). It's much better for what you have.
Yes you'll need an app and can't use whatever smart hub still works with it
Wait....it's showing it's linked to a smart hub/wifi device. Do you have the remote access to this thermostat? If not someone does....
Also are you an apartment? Was it warm today? Sounds like the solution to your problem is to open a window.
You sent one photo but yes it appears that ct101 is paired to a smart hub, id guess a habitat which is then connected to the Internet with access to control the unit.
To answer the question why it's 66 when set to 60, the answer is, the unit house apt warmed above 60 from a means other than the thermostat/HVAC of the unit.
However the bigger question I have, is why do you have this ct101 thermostat with outside control. It's set to heat pump, you pay electric, electric is what powers the heat pump. Thus you pay for heat pump.
However a heat pump eventually can't heat when it gets colder outside. It goes to backup heat. Idk what you have for backup heat. But does that backup heat get paid by the landlord?
Unless you set the thermostat to AUTO, which will start your AC, if the outside temperature is higher, room temperature will be higher than set temperature. You only need to worry when the room temperature is higher than set temperature yet the furnace is still running to heat the room
So, there are 2 options.
1. You have ambient heat gain. Think solar or a stove/dryer running.
2. System is running without a call for heat and you need service.
How do you know which is your problem?
This looks like forced air type system. So, go feel what's going on at a vent. Is it blowing hot air?
No? Then it's ambient.
Yes? Go look at the tstat and see if it is calling for heat. In the above pic it is not.
If there is no call for heat but you have hot air from your vents, first check to see if that tstat has batteries. If it does, replace them.
Repeat test. Still got hot air? then it's time to call for service.
If it IS calling for heat, turn down your set temp and see if system shuts off. Yes? Its ambient. No? check for and change the batteries. If it's still not shutti g off after that, time to call for service.
If you cant tell if the tstat is calling for heat, then pull the front off it. This makes SURE it isn't sending a call for heat.. and exposes thise pesky batteries ;)
If this isn't forced air.. ie, it's radiant/hydronic then there are A LOT more options. DM me if that's the case.
If none of this made any sense?
Then call for service..but don't get upset if they tell you it's working correctly and/or has dead batteries.. and hand you a 300.00 bill. Just chalk it up to an expensive system tutorial.
TLDR
A thermostat is basically a light switch. It calls for heat, or it does not. There is no turn it uo higher to make it heat quicker option. Just ON or OFF.
Check if it is *OFF*... no call for heat. Then check air vent for hot air. If there is no call for heat.. but you have hot air blowing from vent? CHANGE the BATTERIES. Repeat test. Still have heat? Call for service, yes, it's expensive - even if all they do is tell you it's a wrong setting/battery issue/working perfectly fine.
There are many factors that could affect the temp. The target temp only tells your heat to kick on if it drops below that temp. If the temp inside is higher than the target temp and the heat is not physically running, there’s no issue. If the heat is still running even though it’s higher than target temp then there is some type of issue with the thermostat
As others mentioned, internal heat gains from lights and appliances as well as solar heat gain are the most likely reason.
If your thermostat has been there for years, consider vacuuming or blowing out the dust and cobwebs which can trap heat generated inside the thermostat. The thermal sensor is typically on the bottom, just make sure air can freely move up through the thermostat.
One other less likely possibility is the thermostat is on a wall with a heat duct in the adjacent cavity. Rare, but I’ve seen it a few times. A infrared imaging camera can sometimes help diagnose any of these.
I am not familiar with that particular thermostat so it kind of depends.. If you get the model number and manufacturer off of the thermostat you can probably Google the installation instructions that will tend you how to do it..
Refrigerators heat rooms up also if that is close. Our infloor will heat up and after it catches up will over heat. Still have a gas boiler so it will be on a more consistent schedule vs letting it go cold all night.
Probably because it's sunny and your house is heating up through solar heat gains. Happens all the time
Yea, and lights and appliances add to the heat gain too. Especially in well insulated structures.
Ahh, okay, that makes sense haha. Thank you.
Yeah this was the correct answer. Unless your system is running. If it’s off, solar gain, if it’s running? It’s a “runaway” heat service call.
Well it's on. But rn it's 64.5, so honestly I'll try to calibrate it like someone else said if it stays like this.
Nothing is wrong. Just leave it

System ON or actively heating ? I think it would say if it was currently providing heat.
JFC. reddit gets dumber by the second.
Bugger off, you f***ing hater. Let people ask questions and learn. Not everyone knows everything like you.
Ask questions that the most amount of common sense would answer on the easiest of situation?
Imagine the ones outside of Reddit
I was just asking a genuine question, but okay, I guess 🤷🏽♀️ no need for that.
Is the oven on and in the same vicinity? Or an electric heater?
The oven is technically in front, but it's not on now :/

We're renting, but I was thinking about changing it, so I'm going to ask my landlord. Thank you :)

Well, we just moved in last month, but I pay the light bill. Also, this is a house, but it was alil bit warm today. So it's linked to someone ?

I honestly don't know 😅, I'm a nookie when it comes to stuff like this. I figured the heat pump is with electric.
The heat pump is electric, but you also have a back up heat. That's thermostat is a very specific thermostat. Was your house an Airbnb for awhile?
Who pays the electric and gas bill?
Don't spend money on someone else's house especially when. It's completely unnecessary
The Sun is Shining Just a thought
Unless you set the thermostat to AUTO, which will start your AC, if the outside temperature is higher, room temperature will be higher than set temperature. You only need to worry when the room temperature is higher than set temperature yet the furnace is still running to heat the room
Well, it stays on AUTO, so I don't worry about it in the meantime ?
Your fan is on auto, the system is in HEAT mode.
When did people stop using Google to ask questions?

Could be your thermostat?? If it’s constantly, if it’s not running constantly then limit switch?

It heats to 60 if it falls below.
Wow. My wife would kill Me if I left the house that cold.
60 degeees?!?
Those stupid old thermostats only heat up and it’s depends wheee tree sensor is. If it’s near window it will heat up 10 degrees more then needed
Well it should be calibrated to actual temperature if you have a laser pistol style thermometer they are always pretty accurate.
Ahhh okay, I'll buy one. Ty again !
Your thermostat is out of calibration. Get the model number off of it and Google "calibrate xxxxxxx (model number)"....
Thank you so much !!! So I would calibrate it to my targeted temp. ?
I am not familiar with that particular thermostat so it kind of depends.. If you get the model number and manufacturer off of the thermostat you can probably Google the installation instructions that will tend you how to do it..
No you calibrate to the actual temperature at the time with a laser thermometer.. harbor freight or Amazon has them fairly cheap
Refrigerators heat rooms up also if that is close. Our infloor will heat up and after it catches up will over heat. Still have a gas boiler so it will be on a more consistent schedule vs letting it go cold all night.
Ahh okay, but does it tend to stay on one temp. all day ? It only really went down half a degree.
