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.
Generally, the auto setting will start the furnace fan about half a minute after the burner is lit. The fan is turned off about a minute after the desired temperature is reached. The main benefit of setting the thermostat to 'Auto' is that it will result in more energy efficient usage.
• AUTO (automatic) mode
Automatic mode sets the thermostat to follow the temperature program. Operating the thermostat in this mode is the best way to maintain a high level of temperature comfort whilst maximising your energy savings.
The reason they suggest leaving it on auto is so the unit can run at peak efficiency. Allowing the unit to have control over the fan speed generally leads to more consistent temperatures, better dehumidification, and energy efficiency.
Why You Should Normally Set Your Thermostat to AUTO. Compared to the ON setting, the AUTO setting gives you benefits such as: Lower energy consumption. In AUTO mode, the blower fan only runs when necessary, which cuts down your AC system's energy usage.
Yes, Auto mode is intended to save energy. The air conditioner can conserve energy and save you money on your energy bills by automatically adjusting the temperature and fan speed based on the ambient conditions and the presence of people in the room.
When your fan and air conditioner are running all the time, more electricity is produced. All in all, it is better to leave your air conditioner's fan on auto, instead of “On” at all times.
"AUTO" is the more energy-efficient option, as it runs the fan only when heating or cooling is actively needed. "ON" keeps the fan running continuously, which can help with air circulation and filtration but may consume more energy.
AUTO means the fan turns on “automatically” ONLY when your system is heating or cooling your air. When the thermostat reaches your temperature setting, the system, including the blower fan, shuts off. This is the most energy efficient option.
Access the Menu: Tap the menu icon on the thermostat's touch screen. Hold Down the Weather Button: Press and hold the weather button for five seconds. This will bring up the reset menu. Select Reset Option: Navigate through the options until you find “Factory Reset.” Tap on it to select it.
The AUTO setting cycles on and off, which allows moisture from the AC's cooling coils to drip outside, away from your home. Less moisture trapped in the air means your system doesn't have to work so hard. Hands-off operation: One of the main benefits of thermostat AUTO vs ON settings is that AUTO is automatic.
Auto: Fan runs only when the heating or cooling system is on. On: Fan is always on. Circ: Fan runs randomly about 33% of the time. *The circulate option that allows you to set the fan to run a certain amount of time per hour.
Locate the system Slider Switch labeled Heat Off Cool. Slide the switch to the desired setting and either manually adjust the arrows to the desired set point and press hold or establish a schedule for heating and cooling.
If you want to change the heat set point when it says “auto cool, you must first press the mode button until the mode shows “heat”, then use the + or – to change the heat set-point. Then press the mode button to switch the mode back to Auto Changeover.
Leaving your AC fan set to ON allows the moisture in your home to accumulate and reach mold-growing levels of humidity. To ensure that you and your family stay cool and healthy this summer, keep your AC thermostat fan setting to AUTO.
The “Auto” Fan Setting on Your Thermostat
With the “auto” fan setting, you can expect to conserve energy and lower energy bills (because your system fan is not constantly running and constantly using energy).
Your Thermostat is in the AUTO Position
Keeping your thermostat in the AUTO position means less overall energy is being used—and that reduces your utility bills considerably.
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously.
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.
In addition, the auto mode also helps to reduce the running time of the system, which in turn can help to save energy. When the air conditioner is in auto mode, it does not run constantly, but turns on and off automatically as needed to maintain the desired temperature.
Setting your thermostat to auto will allow your system to be more energy-efficient since the fan only runs when the system cycles on, not continuously. Typically, the fan will turn on 30 to 60 seconds after a heating or cooling cycle starts and then turn off a minute after the cycle ends.
There are benefits to having your air conditioner set to “auto” and “on.” The benefits of the “auto” setting include higher efficiency, lower energy bills, better humidity control, less wear and tear on some components, and quieter running.
Running the “auto” function of your air conditioner all day and night isn't the best idea for any home. There are a few reasons you don't want to run your AC system all the time: System stress: Your air conditioner unit needs time to take a break.
The Short Answer Is: When your air conditioning system keeps running and never seems to shut off, the problem could be linked to a number of malfunctioning components – frozen evaporator coils, a clogged air filter, a bad electrical relay switch that needs to be replaced, the fan blowing constantly, dirty condenser ...
