Furrion Thermostat Issue

[jdlong49]

My thermostat is wildly inaccurate but not in a predictable way. Some days it will be off 3 degrees, some days 9. I have a Waggle temperature monitor and a room thermometer to verify. And sometimes it varies wildly within the same day.

When I have the air on, it may be 74 but the thermostat will read 68. Then I set the thermostat even lower to make it kick on and once the compressor turns on, the temperature reading will start creeping up from the incorrect reading of 68 to the correct 74, then it will come down accurately as it cools. Then I can turn the thermostat back up to the actual temp I want. It will get to that temperature and the compressor turns off and everything is good for a while. Then its hot again and the thermostat says 68 but its 73 or 74 again.

With the furnace, It will read warmer than the actual temperature by 6-8 degrees. I have to set it on 77-78 to keep it comfortable on most nights. What puzzles me the most is that it will read one temperature if I have the air on, then I can switch it over to heat and it will tell me it's another temperature....and neither of them will be correct.

If it was consistently off by the same amount I could live with that, but its all over the place. I never know what number I have to set it on from day to day, hour to hour. Its just constantly adjusting it every hour every day.

So put your thermometer next to the thermostat!

That should take care of the problem!

My apologies. I have a 2022 Transcend Xplor 200MK

What thermometer are you referring to? The one I mentioned in the post?

Yes. The thermostat is away from outside walls. That is big.

I still feel like I’m missing something here. The thermometer I bought to verify the accuracy of the thermostat is stuck on the wall right next to it, but I don’t see how that plays into any of this.

Even a few feet separation will give a different reading. It is the only way to calibrate something.

I feel like there might be some confusion, I probably didn't explain it very well. I bought a room thermometer to confirm what I was feeling, that the temperature my thermostat was reading is not the actual temperature. I stuck in on the wall right above my thermostat. It currently says 69 but my thermostat is reading 78. I'm trying to figure out what I need to do to get my thermostat to be accurate. Both my waggle and thermometer are on the same page with my arms and legs about what the temperature is, and the thermostat is always in a very different place with what it believes the temperature is. What I'm wanting to know is if I need a new thermostat, or is there something I can do to make this one work properly.

Have any of your equipment been calibrated?

So if not calibrated what is right?
