Horrible navigation. Poor flow through the menus makes it difficult to do simple tasks such as choosing what mode it is in for home vs away. It is not the least bit intuitive. It should be pretty simple to just tell it when you're home you want Comfort temps and when you're away you want Eco temps duh. From that point you should be able to define Eco and Comfort temps. But no that's another menu. Good luck finding it. Where do you define how long it maintains comfort before it switches to away.
