In the video, we learn about the general structure and operating principle of one of the subsystems of a car engine - the engine cooling system. The video br The Nest Thermostat lights up when you pass by and displays the time, weather, and temperature on its large and bright display. Blending into any home, it is available in a variety of colors and five languages. Additionally, any other smart home device linked to your Google Home system will be able to detect your presence. When your thermostat is in the “on” setting, the blower will run regardless of whether the temperature set point has been reached. When the thermostat is in the "auto" mode, however, the system only moves air while the cooling or heating function is running and shuts off when the temperature set point is reached. Setting the fan switch to A car’s cooling system circulates coolant to dissipate heat from the engine, which is cooled in the radiator before returning to the engine. The thermostat manages this procedure, guaranteeing the engine maintains its ideal temperature range. This mechanism keeps the engine from overheating and maintains its performance. The engine coolant temperature (ECT) ­sensor provides a good illustration of how many on-board diagnostic strategies have changed. An out-of-range ECT ­sensor can affect the PCM’s fuel and spark mapping, variable camshaft timing, transmission, radiator cooling fan and evaporative emissions functions, so it’s important to develop an The thermostat is located inside the thermostat housing. The upper hose of the radiator is connected to the thermostat housing. Without a thermostat or with a failing thermostat, the cooling system will not be able to handle the coolant flow through the radiator and it will become difficult to run the engine within the optimum temperature range. Pull 18/4 or 16/4 cable from the thermostat to the heater, and the same cable from the thermostat to the cooling system. Cooling. Connect the red wire to the R terminal at the cooling system, and the Rc terminal on the thermostat. Connect the white wire to the Y terminal at the cooling system, and the Y terminal on the thermostat. (optional Common function of thermostat. The main purpose of a thermostat is to keep a standard operating heat range in your car’s engine. When you begin your engine cold, the antifreeze / coolant blend is maintained inside the engine by the thermostat. Once the coolant temperature extends to the required starting stage of the thermostat, it opens.

Here are some of the most important system components and their functions. Thermostat: The system’s thermostat allows you to adjust the temperature of your home by automatically telling your HVAC system when to start and stop. Nearly all HVAC systems have thermostats as control systems, though they may be analog or digital. czT5pL5.
