Queen Beds: When using the in-app remote control, the Left Cooling/Heating fan buttons will operate the fan on the left side of the bed. The Right Cooling/Heating fan buttons will operate the fan on the right side of the bed. When using the Programs on the Climate tab, the operation of the fan will be based on the side of the bed you indicated as the side where you normally sleep during app setup. This can be checked by going to Menu-> My Smart Bed-> Setup-> Switch Sides within the app.
Split King & California King Beds (Unsynced): If your two bases aren't synced, all Cooling/Heating buttons on both the in-app remote control and Programs on the Climate tab will only operate the fan on the side associated with each user's app. This can be checked by going to Menu-> My Smart Bed-> Setup-> Switch Sides within the app.
Split King & California King Beds (Synced): If your two bases are synced, Split Fan Mode must be enabled using the physical remote control in order for the Left Cooling/Heating fan buttons to operate the fan on the left-side base and the Right Cooling/Heating buttons to operate the fan on the right-side base. Programs on the Climate tab will still operate the fan based on the side of the bed you indicated as the side where you normally sleep during app setup. This can be checked by going to Menu-> My Smart Bed-> Setup-> Switch Sides within the app.
