What is the difference between a thermostat and a temperature sensor?
The Thermostat (in-stream valve, opens at around 170-degs) and Coolant Temp Sensor (sends coolant temp data to the ECU) are different, and the Coolant Temp Sending Unit is something else (by the bleed valve, sends signal to Temp Gauge on the dash, exclusively).
How does my thermostat know the temperature?
Thermostats use different types of sensors to measure the temperature. The rate at which the target system temperature can change is determined both by the capacity of the heating or cooling equipment to respectively add or remove heat to or from a target system and the capacity of the target system to store heat.
Is a thermostat a temperature sensor?
While most newer thermostats use some form of an electrical temperature sensor, older thermostats used mechanical switches, typically a bimetallic strip with a mercury or magnetic switch.
Why is my Nest thermostat reading the wrong temperature?

If you can’t fix your thermostat problems, contact an HVAC professional soonest possible.
Why does my thermostat not reach set temperature?

Why does my heater keep running after it has reached the set temperature?
When your furnace keeps running after the temperature has been reached: Check the blower motor – Your forced air heating system uses a blower to push air through ducts and into your living space; sometimes, the blower runs at the same time that your furnace is heating the air, but sometimes it runs on its own.
How do you fix a malfunctioning thermostat?
If the thermostat is still unresponsive, make sure the breaker is shut off and remove the cover. If it looks dirty inside, use canned air or a soft artist brush to clean away accumulated grime that may be affecting its functionality. Then look for issues like loose wiring or terminal screws and tighten them up.
