How To Fix Digital Thermostat Reading Wrong Temperature?
Before you start applying our methods it is recommended to plug your thermostat out of the power and let it discharge for a few minutes.
Then plug it back in, turn it on and read the temperatures.
If the reading is still inaccurate, make sure to follow our methods in the order they are listed for best results.
Method #1 Relocate Thermostat
There is a possibility that your thermostat had been installed in a really awkward position.
Users say that this could sometimes interfere with the temperature it is displaying due to the fact that in this specific spot, the temperature varies.
For instance, the warm air goes up to the ceiling and if the thermostat is higher than recommended, it could frequently read higher temperatures.
The best thing you can do is relocate the thermostat to the heart of the room. This way it will measure the temperature specifically where you inhabit and should get the problem fixed.
If this doesn’t manage to get the issue resolved, you can proceed to our next method!
Method #2 Check For Power Problem
Sometimes, your thermostat might be having power issues which can interfere with the measurement of the device.
To check and possibly resolve any power problems, you can try to restart your thermostat. That won’t only help with the power problem, but also contribute as a maintenance act for your thermostat.

Method #3 Replace Air Filters
A common component that could go faulty after a while of using within is the air filters. They are well-known to get filthy which leads to weird odors when your thermostat is working.
