Your wall controller remains the Main and keeps full function. The one catch is that the bus only allows two devices in total, so if you already have an infrared receiver or a second controller fitted, that has to be removed first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I still use the Daikin app?\u003c\/strong\u003e\u003cbr\u003eIf you have a Daikin LAN adapter fitted, yes, both can coexist.
