Your heating and cooling system uses a thermostat to get an accurate reading of your home or office’s ambient temperature. It is a crucial part of all types of HVAC equipment as it helps maintain your desired temperature. Many HVAC experts recommend using a programmable thermostat because it is highly convenient to use. However, many homeowners also ask, “What is a programmable thermostat?”, and “How does a programmable thermostat work?”.

Read on to learn some helpful information regarding programmable thermostats.

Understanding The Programmable Thermostat

A thermostat is a heating and cooling system component equipped with a sensor that allows it to sense and control the temperature. It can also control specific actions within your air conditioner, furnace, or other controlled systems. For instance, it can regulate the flow amount of the heat transfer fluid and turn the unit on and off. These actions help ensure that the set temperatures are reached and maintained within your home or office.

Difference Between Programmable Thermostats Vs. Manual Thermostats

A programmable thermostat differs from an ordinary one in that a programmable thermostat automatically adjusts the temperature. This adjustment is based on the settings you input into the system. You can set the temperatures lower or higher as per your preferences at different times of the day.

Most modern thermostats are digital. There are still some non-digital ones that can be found in older homes and offices. Digital thermostats are equipped with a thermistor that measures the temperature. This component has metals that change along with the changes in the surrounding temperature. The thermistor is what allows temperature electrical resistance changes as well.

Thermostat Microcontroller

The microcontroller is another crucial part of your thermostat. It is responsible for measuring the electrical resistance, which is converted into the temperature reading of your home. This is how digital thermostats sense temperature. It has programmable settings so you can adjust the thermostat to turn the temperature up and down at varying times. For instance, you could program the thermostat to turn the heat up in the morning then turn it down after leaving for work. It can then turn up the heat again five minutes before you go home. You can also set your programmable thermostat to regulate the temperature at a 24-hour period, depending on your home’s temperature fluctuations within that time frame.

A programmable thermostat is also beneficial if you utilize zoning in your home. This is when different zones or areas in your home are cooled or heated using varying temperature settings. This setup is ideal for large, multi-level houses. Keep in mind that hot air rises, so rooms on the lower floors have a lower temperature than those on the upper floors. This problem is easily remedied with a programmable thermostat in different zones as it lets you have better control of the temperature. This way, it remains consistent and constant throughout.

Benefits of A Programmable Thermostat

Listed below are a few of the advantages a programmable thermostat brings to your home:

Automatic Temperature Adjustment

A programmable thermostat can cool or heat rooms at different times. It does so automatically, so you do not need to keep adjusting the temperature throughout the day. This way, it is more convenient as you do not even have to go near your thermostat to change the temperatures when required.

Improved Comfort

A programmable thermostat adjusts the thermostat automatically. Therefore, the rooms in your home maintain the set temperature during the day, and you receive the comfort you and your family need.

Improved Temperature Control In Zones

Achieving enhanced temperature control for zoning is easy when you use a programmable thermostat. This is because it allows rooms or HVAC zones to be heated and cooled independently of each other. You can even switch the thermostat in unoccupied rooms.

Less Stress On An Older HVAC System

If you have an older heating and cooling system at home, a programmable thermostat can help ensure less strain during your system’s operation. This is advantageous if your system is constantly in operation as it helps reduce worn-out components. It can also prolong your old HVAC unit’s lifespan.

A programmable thermostat enhances your home’s cost-effectiveness. This is because it allows you to change the temperature settings to fit your daily schedule. Therefore, your HVAC unit doesn’t have to be running at 100% all day long. The temperatures can be turned up or down, and you can even turn the system off, depending on the occupant’s preferences.

What If I Don’t Want The Automatic Temperature Setting?

The automatic system of all programmable thermostats can be overridden so that you can operate it manually. This way, you still have control over your system, but you don’t have to set the temperatures automatically. However, consider remote control and monitoring for convenient use. You won’t have to go near your thermostat or even be at home to change the temperatures whenever you want. Many modern thermostats have Wi-Fi capabilities, so you can remotely program them via your smartphone or laptop. This is a convenient feature for when you forget to set your HVAC system and are already out of the house.

Do You Need A Programmable Thermostat?

A programmable thermostat is ideal for homeowners who have a regular schedule. It is also useful for people who want better temperature control in their homes without manual HVAC system manipulation. The programmable thermostat can be programmed to cool down or heat your home at specific periods. You can even keep this setting for a long time. Opt for a programmable thermostat if you want to enhance your home environment’s temperatures without too much manipulation.


A programmable thermostat offers convenience, cost savings, better comfort, and improved temperature control. It is an excellent choice for homeowners and building occupants who like specific temperatures at certain times. A programmable thermostat allows you to have improved control in an enclosed space like your home or office. If this seems like something you are looking for, contact your local HVAC professional to discuss your needs. They can determine the most suitable features to fit your home heating and cooling requirements and preferences.
