A thermostat is used to set the room to your desired temperature, whereas a thermometer just measures temperatures
The temperature sensor is most likely a bi-metal strip type thermostat, or two for different temperatures. Newer machine may use a thermistor.
A thermostat controls temperature, a thermometer measures it.
In a car thermostat the element is wax
A humidistat senses humidity, thermostat temperature.

Depending on your temperature setting, usually the best is about 70 degrees, it's best to set the thermostat, and leave it at a constant setting. Resetting your thermostat to higher temperatures requires the furnace work harder, and will usually increase your utility bill.

Or, if everything else is operating properly, it could be the thermostat or a blocked radiator, but I'd focus on the thermostat first. Be certain that the engine is at normal operating temperature when looking to see if coolant is circulating. A properly operating thermostat will prevent the circulation of coolant while engine temperatures are below operating temperature.
A thermostat is supposed to maintain a constant temperature or temperature range in an area or for a device.
The thermostat's main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator. At low temperatures, the outlet to the radiator is completely blocked -- all of the coolant is recirculated back through the engine. Once the temperature of the coolant rises to between 180 and 195 F the thermostat starts to open, allowing fluid to flow through the radiator. By the time the coolant reaches 200 to 218 F, the thermostat is open all the way. It preforms this feat because there is wax inside the thermostat that melts at a preset temperature. If the thermostat is rated at 190 degrees F that is when it opens. That is it's temperature rating.

To make sure that the temperature is at the desired temperature
Best way to tell your normal operating temperature is to visit an auto parts store and ask them what the OEM thermostat temperature is (or you can look it up yourself on Autozone.com). Most cars these days will have around a 190 degree thermostat. Your car will run slightly hotter than that temperature as it is needed to maintain the thermostat in an open position. With that thermostat you can expect to see the temperature of the water stay around 205-210. If the water temperature ever starts to get above 240 you should shut the engine down to avoid damage and have the cooling system checked. Temperatures above 260 WILL cause significant engine damage.
A thermometer does nothing in a furnace control system other than indicate temperature at a thermostat. A physical thermostat on the other hand controls variances of temperature (called anticipation) using the principles of a thermometer which is expansion of a liquid in a sealed capillary/bulb. A thermistor is another device used in electronic temperature measurement at nominal to extreme temperatures. It measures the resistance of power to indicate temperature.
Nothing in your cage should be over 95 degrees. Get a thermostat and monitor temperatures andhumidity. Accurite has an indoor/outdoor with probe and humidity device that is fantastic. Outdoor probe goes on the hotspot and the device goes in a good place to monitor air temperatures. It is not a thermostat. A thermostat actually adjusts temperatures. Hydrofarm's thermostat is a good, cheap one.
