Cool. Your system only cools your home. It won't start heating unless your Safety Temperatures are reached. Your thermostat starts cooling to try to maintain any scheduled temperatures or a temperature you've manually selected.
Thermostat Operation
The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. You can easily save energy in the winter by setting the thermostat to around 68°F to 70°F while you're awake and setting it lower while you're asleep or away from home.
AUTO is significantly more energy efficient between the two modes since the fan is only running when your AC is going through its cooling cycle. This takes less power, which is more budget-friendly, with some estimates showing you can save as much as $50 per month just by keeping your AC on AUTO.
You'll want to have your thermostat set to heat mode in the wintertime and air conditioner auto mode in the summertime. In order for your system to run on auto mode, you'll need to have either the heat mode or cool mode on. This way, your thermostat knows whether to turn on the furnace or the air conditioner modes.
If the ``cool on'' is flashing then that means that cooling is needed but it is waiting until that delay is finished before it will give the call.

When you see “Cool On” flashing on your thermostat, it usually means that your AC is trying to cool your home. The flashing message is a signal that the system is in the process of starting up. It might be waiting to make sure everything is ready before it starts cooling.
Eco or energy-saving mode
This is the ideal mode for users looking to save up on energy bills by toning down the performance of the AC and its compressor. Eco-mode uses less electricity by automatically adjusting the fan speed and temperature, while still maintaining a comfortable level of cooling.
Cool vs.
As you've likely guessed, the cool setting is for air conditioning, and the heat setting is for warming up your home. While these settings are fairly straightforward, it's important that you understand where they are on your thermostat.
The cool mode is only ideal when you need your air conditioner to cool significantly, as leaving this on the entire time won't really guarantee the cold temperature to be maintained.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
As mandated by the Ministry of Power, Government of India, all AC manufacturers must fix the default temperature setting at 24°C. So, it is better to set the right temperature at about 24-25 degrees Celsius. This will help in cooling the room faster.
While the standard room temperature of 72 degrees Fahrenheit is commonly favored by many, others argue for higher settings, particularly when it's hotter outside.
AUTO means that the fan turns on automatically only when your system is heating or cooling air. Once the thermostat reaches the desired temperature, the entire system shuts off until the next cycle. ON means that the fan is constantly on and blowing air when your HVAC system is not heating or cooling air.
The U.S. Department of Energy recommends 78° as the best temperature setting for your air conditioner during the daytime. And 82° for sleeping in the summer.
Cool is the other essential thermostat setting. It works similar to heat, but instead of running the heater, this mode runs the air conditioner. The Cool mode lets you pick your preferred maximum temperature. When the house is cooler than this temperature, the air conditioner will turn off.
But setting the thermostat really low doesn't increase your air conditioner's cooling capacity. “People think, 'If I make the thermostat set point 60, I'll get more cooling than a set point at 70,' but that's not correct,” Liu said. “You get the same amount of the cooling.”
Simply adjusting your thermostat by one or two degrees can lead to noticeable differences in your monthly utility costs. During the winter, it's good to try and keep your thermostat set at around 68 degrees or less. During the summer, try and keep your thermostat set at 75 degrees or higher.
In conclusion, auto mode in air conditioning not only helps save energy and reduce costs in the long run, but also improves indoor air quality, offers greater control and customisation, and can be more comfortable for the user.
WHAT IS THE BEST MODE FOR AC IN SUMMER? In summer, the best mode for your air conditioner is the "Cool" mode, set to a comfortable temperature around 78°F when you're home. This setting efficiently reduces indoor humidity and maintains a comfortable environment without overworking the AC system.
It's a safety delaying measure that lets the AC system prepare. It also protects the compressor and prevents the unit from short cycling. The flashing is usually nothing to worry about unless it keeps going after several minutes. If that's the case, there might be something wrong with the thermostat or the AC unit.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Cooling Mode Symbols
Some thermostats will indicate the air conditioning is on with clear text that reads “AC On” or “Cool On.” Other thermostats may use snowflake symbols to indicate the same thing. Either way, it simply means that the system is in cooling mode.
