Ecobee smart thermostats allow you to control your home’s temperature quickly from your own cellphone or manually on the device, but why does ecobee say “Calibrating: Heating and Cooling Disabled”? Let’s talk about this in detail and solve this issue.
So, why does my ecobee say calibrating? When you install your ecobee for the first time or after it reboots, the device measure the room temperature and therefore you get a calibrating message. The whole calibration process takes around 10-20 minutes.
There could be several reasons for the ecobee calibration message, you would find all the possible reasons and how to stop ecobee from unnecessary rebooting in this article.
Possible reasons for Calibrating & Ecobee Troubleshooting
Troubleshooting your Ecobee is only possible when you know the exact reason for the message “Calibrating: Heating and Cooling Disabled”. So, we have included the possible reasons for Ecobee calibrating message and how to troubleshoot them easily.
It’s a Basic Error
After setting up ecobee for your home, it may have some technical issues getting used to the surroundings at first.
If the temperature it saying your home is set at is a degree or so off, that’s normal.
If it’s wildly off the actual temperature, it needs some help calibrating.
That’s when you may see a message that reads: “Calibrating: Heating and Cooling Disabled.”
A good solution is adjusting the temperature manually, which is easy to do through your ecobee’s display screen. Go to Settings, then Installation Settings, then Thresholds.
From there, select Temperature Correction” and change the temperature reading.
The whole process should take about 20 minutes to get your ecobee on the right track, and heating and air conditioning won’t be available during the re-calibration.
The ecobee calibrates again if there’s any type of outage, whether a switch is turned off or an outage is caused by bad weather or faulty wiring.
Whatever the case, an ecobee’s screen may go black and power off and on again, leading to a “calibrating” message.
Every time an ecobee loses power, it will calibrate again in this way, according to ecobee support team.
It’s Struggling with a Power Source
Ecobees require a 24VAC power supply 24/7. If that’s interrupted, says support.ecobee.com, the ecobee won’t power back on until 24VAC is restored, losing its power to heat and cool and leading to a “calibrating” message.
If your HVAC’s safety feature fails, it will trigger a power loss on your thermostat.
This may happen because the 24VAC transformer doesn’t have a good-enough volt-ampere’s rating to handle multiple thermostats, including your ecobee if it’s part of a group of other thermostats in your home, says support.ecobee.com.
There’s a Wire Issue
According to Ecobee support, if your thermostat wires aren’t properly connected to the backplate, the thermostat will not power on.
Once it’s connected properly — fully inserted without spaces between the thermostat and the backplate, it will power on and lead to a “calibrating” message.
You’re Using it For the First Time
The ecobee will display the “Calibrating: Heating and Cooling Disabled” message when you boot it for the first time. This simply means it’s starting up and getting a reading on your home’s temperature for the first time.
After a while, usually about 30 minutes or so, the messaging will return to normal and it will start cooling or warming your home.
If the message stays after a good amount of time, there may be something off with your unit or how you installed it in your home.
You’re Resetting It
When you reboot your ecobee for whatever reason, all the rebooting, programming, and configuration options restart as well and reconfigure, leading to the familiar “calibrating” message.
You’ve Decided to Turn It Off
If you changed your mind about your purchase then changed your mind back — or decided that you want to ecobee in a different location, turning it off and then turning it back on will also reboot the system, leading to the “calibrating” message.
It Keeps Restarting
There are a few reasons why your ecobee will keep restarting, leading to the “calibrating” message and a reboot.
Your furnace may overheat, leading to a sensor trip, cutting power to the ecobee. Or your HVAC system may cut power to it. It’ll go through a restart/reboot every time either of these happens.
You’re Fiddling With the Humidity Settings
An ecobee also measures your home humidity and comes equipped with a cluster of sensors that convey accurate humidity levels.
Just as with inaccurate temperature readings, if there are issues with humidity readings on your ecobee (likely it’s displaying something different than actual readings), a recalibrate and sync fix will get it working again in about 20 minutes or so.
There’s also a humidity correction setting that lets you adjust the setting by 10%, up or down, leading to another “calibrating” message.
You see the “Calibrating: Heating and Cooling Disabled” on your Ecobee when it boots. The Ecobee thermostat requires calibration to get an exact reading of the room temperature which takes around 20 minutes.
Note-Remember not to use AC or heater during your ecobee calibrates.
