There are many automatic functions on the thermostat, and resetting them could help if turning down the temperature doesn’t work for you.
Another reason for not turning off your thermostat could be that it is set on an automatic timer setting, and after a certain period, it will stop.
You can turn off the timer by holding the thermostat for five seconds and then restart it. The reset button might be located down the base or right side of the furnace unit.
Still, if you cannot find the reset button, there’s another option for you: removing the batteries from the thermostat for at least one, and after that, you can put them back. This will restart all the programs and shut down the previous running programs.

If you do the following things, then change your filter frequently you keep your windows and doors open, you smoke inside your home, your air filters are small in size, you keep your furnace on for more than 8 hours a day, and above all you have pets.

After that, wait for one hour; during this time, your furnace will shut down when it detects the new air filter.
