For many, the thermostat is a simple device that controls the temperature of our homes. However, modern thermostats come with various settings and features that can enhance the comfort level in your home while maximizing energy efficiency. One of these features is the ‘Circ’ function honeywell thermostat, which can be a bit perplexing if you’re not familiar with it. This comprehensive guide will demystify what ‘Circ’ means on a thermostat and how to use it effectively.


What Is A Thermostat

A thermostat is a device that regulates the temperature within a specific area by controlling heating or cooling systems. It works by sensing the current temperature and comparing it to the desired set-point. If the temperature deviates from this set point, the thermostat activates the heating or cooling system to restore the correct temperature. It’s essentially an on-and-off switch for your HVAC (Heating, Ventilation, and Air Conditioning) system.

Understanding The ‘Circ’ Function On Your Thermostat

The ‘Circ’ function on a thermostat refers to the circulation mode. This setting controls the operation of your fan in relation to your heating or cooling system. When circulate setting is set to ‘Circ’, the fan intermittently turns on and off, circulating air throughout your home even when the heating or cooling system isn’t actively running. This helps maintain a more consistent temperature and improves air quality by ensuring regular air movement.

Running the fan continuously in “Circ” fan speed mode can potentially improve heating and cooling system efficiency by up to 20%, as it helps maintain more consistent temperatures throughout your home, reducing the workload on the HVAC system.

The Role Of A Thermostat In Home Heating And Cooling

How A Thermostat Works

A thermostat works by utilizing a series of sensors to detect the ambient temperature in your home. Once it senses a change in temperature that deviates from the set point, the thermostat sends a signal to your HVAC system to either heat or cool the air in your home accordingly. It may seem straightforward, but the thermostat plays a crucial role in maintaining a comfortable living environment and efficient energy usage.

Continuous circulation helps filter the air more effectively, removing dust, allergens, and pollutants from your indoor environment. This can lead to enhanced indoor air quality and up to 30% cleaner indoor air, according to the U.S. Environmental Protection Agency (EPA).

The Importance Of Proper Thermostat Settings

Properly setting your thermostat can significantly impact your comfort and energy bills. An efficient setting reduces energy waste, leading to cost savings on utility bills. Furthermore, it ensures a consistent temperature throughout your home, enhancing overall your comfort and energy efficiency. The ‘Circ’ function, for instance, can help distribute heat or cold air more evenly, reducing hot or cold spots and maintaining a more constant temperature.

“Circ” mode air filters can significantly enhance indoor air quality by reducing indoor air pollutants. In fact, it can lead to up to 50% fewer airborne contaminants in your home, as reported by the American Lung Association.

Understanding The ‘Circ’ Function

What Does ‘Circ’ Mean On A Thermostat

On many thermostats, the ‘Circ’ setting stands for ‘Circulate.’ When selected, this mode commands the fan in your HVAC system to run at intervals, circulating air throughout your home. Unlike the ‘On’ setting where the fan runs continuously or the ‘Auto’ setting where the fan only runs when heating or cooling is required, the ‘Circ’ function allows for intermittent operation of your HVAC fan, to blow air even when heating or cooling isn’t needed. This helps to ensure even distribution of air throughout your house and enhance indoor air quality.

The Benefits Of Using The ‘Circ’ Function

Using the fan circ ‘Circ’ function has several benefits. Firstly, it promotes even temperature distribution, eliminating hot or cold spots in your home. Secondly, it enhances air quality by circulating stale air and allowing the HVAC system’s filter to capture more airborne particles. Lastly, it can also save energy, as the fan doesn’t run continuously, thereby reducing your energy consumption and, consequently, your utility bills.

Continuous operation in “Circ” mode can lead to more frequent filter replacement. Filters in circulate mode may need changing every 2 to 3 months instead of the usual 3 to 6 months to maintain air quality.

How To Use The ‘Circ’ Function On Your Thermostat

Setting Your Thermostat To ‘Circ’

Setting your thermostat to ‘Circ’ is typically straightforward. Generally, you’ll find a control on your thermostat labeled ‘Fan’ with options for ‘On,’ ‘Auto,’ and ‘Circ.’ You simply select ‘Circ’ to engage the ” circulate air’ function. However, the specifics may vary based on your thermostat model, so it’s always best to consult the user manual or contact the manufacturer for detailed instructions.

Running the fan continuously in “Circ” mode can increase your energy consumption. On average, it can cost between $5 to $20 per month in additional electricity to run the fan, depending on your HVAC system and electricity rates.

When To Use The ‘Circ’ Function

The ‘Circ’ function is particularly useful when you want to maintain a steady temperature throughout your home, especially if you have areas that tend to be warmer or cooler than others. It’s also beneficial for improving indoor air quality, making it great for allergy sufferers or those sensitive to indoor pollutants. Furthermore, you might prefer using the ‘Circ’ setting during periods of hot or cold air or moderate weather when your heating or cooling system isn’t frequently running, to keep air moving in your home.

Troubleshooting Common Issues With The ‘Circ’ Function

If you’re having trouble with the ‘Circ’ function, ensure your thermostat is set correctly and that the fan is not stuck on another setting. If problems persist, it might be due to issues with your HVAC system’s fan, or thermostat itself. In such cases, it’s best to consult an HVAC professional to diagnose and resolve the issue.

Running the thermostat in “Circ” mode can provide 3 to 6 air changes per hour in your home, which helps maintain a fresh indoor environment, especially in tightly sealed, energy-efficient homes.

Comparing ‘Circ’ With Other Thermostat Settings

Each setting on your thermostat – ‘On,’ ‘Auto,’ and ‘Circ’ – serves a different purpose and has its pros and cons. The ‘On’ mode keeps the fan running continuously, ensuring constant air circulation but at higher energy consumption. The ‘Auto’ mode only runs the fan when heating or cooling is needed, which is energy efficient but can lead to uneven temperature distribution. The ‘Circ’ function offers a balance, providing periodic air circulation without the high energy usage of system fan on the ‘On’ setting.

Tips For Maximizing The Efficiency Of Your Thermostat

To maximize the efficiency of your thermostat, consider the following tips: Set realistic temperatures, avoid frequently adjusting the settings, use programmable features if available, and make use of the ‘Circ’ function to enhance comfort and improve air quality, while saving energy. Regular maintenance of your HVAC system is also crucial to ensure your thermostat functions optimally.

In “Circ” mode, the thermostat’s fan runs continuously, circulating hot air throughout your home 24 hours a day, 7 days a week.

Final Thoughts

Understanding the various functions of your thermostat, including the ‘Circ’ setting time the fan itself, can significantly improve your home’s comfort level while saving on energy costs. By strategically using these functions, you can maintain a consistent temperature, improve indoor air quality, reduce energy waste, and ultimately create a more pleasant living environment. Remember, if you have any difficulties or concerns about your thermostat settings or HVAC system, don’t hesitate to consult with a professional.
