Most domestic thermostats are located in a central location in the house, such as a pill, so the detected temperature is an average of the total temperature in the house. In most cases, the temperature sensor is inside the thermostat, but not always.
Where is the temperature sensor placed?
Ideally temperature sensors should be installed away from windows, ventilation units or any excess air movement. Temp sensing, particularly in rooms with convective heating such as radiators is best measured at or near head height, so around 1500 to 2000 ffl (finished floor level).
How do you clean a thermostat sensor?
In cases where there's a lot of dirt, grime or corrosion on the contacts, use a small amount of rubbing alcohol to clean them. Take care not to touch other parts of the system.
Is there a thermostat sensor?

What temperature is too cold for a house?
What Temperature is Too Cold for a House? While everyone has a different tolerance to cold, ideal winter heat settings should generally be at or above 63 °F (17 °C). Excessive cold (anything below 62 °F or 16 °C) in your home can actually raise your blood pressure as your blood “thickens” in the chilly temperatures.
Why is my house colder than the thermostat?
There may be drafts and pockets of colder air near the floor; The walls are colder and don't emit the usual amount of infrared radiation, so you lose heat due to your body emitting more IR than it receives; You may spend more time indoors and hence have less physical activity, so your body generates less heat.
