The touchscreen may tell you why your Ecobee smart thermostat isn’t working correctly. We have provided information about what this means for users whose Ecobee screen says “Calibrating: Heating and Cooling Disabled”. However, there are various methods mentioned below you can use for troubleshooting Ecobee calibration.

 

“Calibrating” refers to the Ecobee thermostat sensor determining the current indoor temperature. When Ecobee is first installed, and whenever it reboots, it calibrates. The process takes between 5 and 20 minutes.

 

During calibration, you cannot use your heater or air conditioner, which can be inconvenient if your thermostat is often restarting. There are several reasons why Ecobee reboots after installation. We have provided information on each of these reasons and how to prevent Ecobee from rebooting unnecessarily below.

 

What It Means When Ecobee Says “Calibrating?”

Your thermostat needs to be calibrated to determine the current temperature inside your home or office. The Ecobee Thermostat measures temperature, humidity, and occupancy with its built-in sensors.

In addition to the built-in sensors, you can purchase wireless sensors for other rooms. An Ecobee thermostat can support up to 32 sensors!

Note: The following article provides excellent tips on placing wireless sensors to get the most accurate readings.

 

Calibration After Initial Installation

Installing Ecobee is easy to do by yourself; it takes about 45 minutes. However, after installation, you will need to wait for another 5-20 minutes for the device to calibrate. During this time, you cannot use your heater or A/C.

If your thermostat still says it’s calibrating after 20 minutes, the wiring may be an issue. Then, remove the thermostat from the wall to check the wires. All the tabs next to the wire terminals should be pressed entirely down, and each wire should be in the correct terminal. The wire letters correspond with the following wire colors:

 

 

Wire	Wire Color
C	Blue or black
G	Green
R, RC, or RH	Red
W	White
Y or Y1	Yellow

 

Wires can sometimes be of different colors. Contact an electrician if this is the case for your thermostat wires or if you suspect another issue with the wiring.

You will not have a C wire if you use a Power Extender Kit.

Recalibration After Ecobee Reboot: Troubleshooting Ecobee

Ecobee will need to be calibrated every time it reboots. This can happen for many reasons, including:

 

• You lose power temporarily.
• Ecobee updates its firmware.
• The furnace overheats.
• You have water accumulating in your air conditioner.
• You have corroded or damaged thermostat wires.
• If you lose power or flip the breaker, your Ecobee will automatically recalibrate when the power is restored. You have to wait.

 

Ecobee also updates its firmware regularly; an update may cause your thermostat to recalibrate. This may take a little longer than a regular calibration. If your device is calibrating for more than an hour, please contact Ecobee customer service for assistance.

 

Ecobee Calibration Troubleshooting

Here are a few steps you can take to troubleshoot your Ecobee if it is having problems calibrating:

 

What to Do If Ecobee Keeps Rebooting: Troubleshooting Ecobee

Your Ecobee is likely to reboot often if the thermostat or another part of your HVAC system is malfunctioning. It may be as simple as changing the filter in your furnace or cleaning the drain pan in your air conditioner.

However, other problems can be more complicated and require handling wires. If you are not comfortable doing this yourself, hire an HVAC technician.

Ecobee Calibrating for Too Long

Calibration should only take 20 minutes at most. Indeed, some users have reported that their devices calibrate for more extended periods, sometimes up to 12 hours; this is not normal and is likely caused by an error.

Try power cycling your Ecobee if it is calibrating for an unusual amount of time by taking it off the wall and putting it back on. Afterward, wait 20 minutes to see if it stops calibrating.

You can also power cycle your Internet by unplugging your router and modem for at least one minute and then plugging them back in.

Additionally, you will want to contact Ecobee customer service if your thermostat still says “calibrating” after a long period.

 

Incorrect Ecobee Thermostat Calibration

There are times when the temperature reading on your Ecobee may be inaccurate after calibration. However, temperatures that differ by one degree are average, but it can be a problem when they are off by more than that. However, you can use the steps mentioned below to troubleshoot Ecobee calibration.

You can manually adjust the temperature reading as follows:

 

• Click on the menu button on the Ecobee display.
• Click on “Settings.”
• Choose “Installation Settings.”
• Click on “Thresholds.”
• Then select “Temperature Correction.”
• If necessary, adjust the temperature reading.

 

Conclusion:

If your Ecobee Thermostat says, “Calibrating: Heating and Cooling Disabled,” the thermostat sensor(s) are working on determining your home’s current temperature. Moreover, the calibration process happens after you install your thermostat and whenever it reboots. You can’t use the heater or air conditioner during this time, but it should only take up to 20 minutes.
