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

Software and security questions
- Q: How can I be sure my D6 controller is running the most up-to-date firmware?
A: When your D6 controller is connected to Wi-Fi, it will automatically receive over-the-air firmware updates from Resideo. These firmware updates contain things such as new features as well as security upgrades. Keep your D6 controller connected to Wi-Fi to ensure it receives these updates. - Q: How can I prevent a cybercriminal from making unauthorized changes to my D6 controller?
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.
