Quick reference
Choose a location
Choose a location where the controller’s signal has a clear path to the ductless unit. Remove the batteries from the remote controller that came with the ductless unit. That way the two controllers won’t send conflicting commands.
The controller sends an IR signal from three places. One on each side, left and right, and one from the top. Consider them when you choose a location.

Software and security questions
Q: How can I be sure my thermostat is running the most up-to-date firmware?
A: When your thermostat is connected to Wi-Fi, it will automatically receive over-the-air firmware updates from Honeywell. These firmware updates contain things such as new features as well as security
upgrades. Keep your thermostat connected to Wi-Fi to ensure it receives these updates.
Q: How can I prevent a cybercriminal from making unauthorized changes to my thermostat?
A: If a cybercriminal gains access to your Wi-Fi router, they can tamper with a wide range of online activities, including the settings on your connected devices. Make sure you change the default password on your Wi-Fi router, and when you select a new password, make sure it uses multiple upper- and lower-case letters and special characters.
The product should not be disposed of with other household waste. Check for the nearest authorized collection centers or authorized recyclers. The correct disposal of end-of-life equipment will help prevent potential negative consequences for the environment and human health.
