How Does An Ecobee Thermostat Work?

Ecobee produces a smart thermostat that is directly connected to the HVAC system in your home. It uses a built-in temperature sensor to instruct the HVAC system when to turn on and off. 

The Ecobee thermostat uses additional sensors that detect motion and humidity to perform its smart functions, such as the ability to use your smartphone to remotely manage the temperature of your home.

Wi-Fi connectivity allows Ecobee thermostats to obtain local information such as weather and electricity prices. Calculations are made using all of this data to determine the appropriate temperature setting to use.

Additionally, the remote sensors on the thermostat can be installed in several locations throughout your house to monitor and regulate the temperature as well as to track occupants. 

With the use of geofencing, Ecobee utilizes the position of your mobile device to determine when you are leaving or coming home and alters the temperature accordingly. 

The thermostat also comes equipped with smart speakers which allow you to use voice commands to manage your Ecobee. Other common Alexa features, such as drop-ins and phone calls, can also be accessed when using this speaker.

Why Does My Ecobee Thermostat Make Clicking Noise? 

Different problems can cause the clicking sound that an Ecobee thermostat makes. While some of these issues are minor and easily fixed, others can be quite problematic. Here are some common reasons why an Ecobee thermostat makes a clicking noise: 

Dead Thermostat Battery 

Some thermostats are connected directly to your home's electrical system while others are battery-powered. The usual battery-operated thermostat uses 9-volt batteries. 

If your Ecobee thermostat is battery-powered, a persistent clicking noise could be an indication that the batteries are dead or close to dying.

Clogged Filter

Although dirty filters may seem like a minor issue, they can actually do more harm than you might think. Your system will suffer from blocked airflow in many ways and it may lead to short cycling. Your thermostat will produce a clicking noise as a result of this.

Low Voltage

If your Ecobee thermostat makes a clicking noise, there may not be enough voltage between the RC and C terminals. This may be the result of a faulty C wire or a C wire that is wrongly attached to the side of the HVAC equipment. 

As a result, when your thermostat requests hot or cold air, it won't receive it. The relay will keep retrying, making a clicking sound along the lines.

Wrong Placement 

The ideal location for an HVAC thermostat should be a spot where the thermostat can accurately gauge the room temperature. This means that it shouldn't be installed where it will be exposed to direct sunlight, cold winds from windows or vents, or too close to a hot bathroom or kitchen.

If your thermostat is located somewhere where it may pick up quick changes in temperature, it may start clicking as the temperature in the room changes.

Dirty Condenser Coil

Your air conditioner's exterior unit houses the condenser coil. It is directly behind the metal wiring or fins that cover the unit. Airflow will be restricted if the fins become blocked with dirt and debris. 

Dirty Pilot Ignitor

Your HVAC system will fail to respond if the pilot igniter sensor in your heating system gets clogged. When this occurs, the thermostat will keep clicking until it receives a response.

What To Do If Ecobee Thermostat Starts To Make Clicking Noise?

There are several things you can do to stop the clicking sound an Ecobee thermostat makes, and they include these steps: 

Check The Thermostat For Damaged Wires 

You need to open the circuit board and unplug the thermostat wires from the terminals. The red and white wire should next be tested with a voltmeter. If there is no signal or the voltage is lower than 24V, it means that the wire is damaged and needs to be replaced.

Clean Your Air Filter

Check the air filter for dirt and ensure your unit is receiving enough airflow. If you have a dirty filter, make sure to clean it. Also, make sure that the blower motor is not damaged. Remember to check your condenser coil as well.

Ask A Professional For Assistance 

If the mercury bulb is cracked or one of the thermostat's relays has failed, the thermostat may start clicking. Complex issues like this should be handled by a professional.  

Does An Ecobee Thermostat Have A Siren?

The Ecobee smart thermostat and the camera are equipped with sirens. These have a midrange frequency that resembles a metal bell ringing, with a higher-frequency electronic tone pulsing in the background.

The sirens are rather quiet but can help deter a potential burglar as louder sirens do. Users of Ecobee Smart Security can choose to get notifications with this new function.

How Do I Turn Off Ecobee Notifications?

By choosing reminders and alerts from the menu page or on the web page under this tile, you may access and customize your reminders and alerts on your thermostat. 

You can enable, disable, and customize the notification and alerts on your thermostat through your mobile device, or the web interface, depending on your preference. 

If you want to turn off the Ecobee notifications on your thermostat's screen, choose "No". Alerts will still be shown on the web portal instead and delivered through email. 

Does My Ecobee Thermostat Have A Battery?

Yes, the Ecobee thermostat has batteries. Batteries inside the thermostat serve the main purpose of preserving any preset data in the event of brief power outages so that your heating and cooling system can continue operating without interruption. 

When the battery is low, the thermostat will cease operating, and your heating or cooling systems won't work. The display screen on the thermostat may go blank due to low batteries.

Is There A Reset Button On Ecobee Thermostat?

Yes, the Ecobee thermostat has a reset button. All saved preferences, settings, and registration data are deleted when an Ecobee device is reset to its factory default settings. 

However, depending on the model, there are different ways to reset your thermostat. The battery can be installed backward for 5 seconds, a reset button can be pushed with a pin or paper clip, or the thermostat's breaker turned off for 30 seconds.

Are Ecobee Thermostats Worth It?

An Ecobee thermostat is beneficial given its various features. Older thermostat models require manual adjustment of the indoor temperature using a dial or level. This isn't usually very effective, particularly if you're not always around to adjust the thermostat. 

Using the Ecobee thermostat can help you save energy and money. You won't have to stress about manually adjusting the thermostat's temperature when you use an Ecobee smart thermostat. 

Ecobee smart thermostats read the temperature in each area and modify themselves following room or surrounding variables to boost your comfort in addition to allowing you to regulate your heating and cooling remotely.

Also, these Wi-Fi-enabled thermostats learn your schedule and preferences, which enables them to automatically modify the temperature setting to suit your needs.

Some models available today can alert you when it's time to replace your air filter and also assist you in identifying issues with your air conditioner.
