Frequently Asked Questions

Why does my Ecobee keep losing Wi-Fi?
Common causes include router issues, signal interference, outdated firmware, or incorrect network credentials. Try moving your router closer or using a Wi-Fi extender.
Does Ecobee work on 5 GHz Wi-Fi?
No, Ecobee thermostats only support 2.4 GHz networks. Make sure your router broadcasts a 2.4 GHz band and that your thermostat connects to it.
Will error code 14 affect my heating or cooling?
No, your thermostat will still control your HVAC system based on its schedule. Only remote access and smart features will be unavailable until the Wi-Fi is reconnected.
How do I factory reset my Ecobee?
Go to Main Menu > Settings > Reset > Factory Defaults. This will erase all settings and require you to set up the thermostat again.
Can I use the Ecobee app without Wi-Fi?
No, the app requires an internet connection to communicate with your thermostat. You can only control it directly from the thermostat itself.
