I think the computer can choose any 2 points where are different temperatures and tell the air conditioner to send warm or cool air to fix it for the perfect one. [壁の近くと窓の近く] is an example and can be any 2 places where the temperatures are different. I think you can not add "と” but you can add similar one "の”.
And I remember your past question 学校が子どもの親などとトラブルになる.It is the similar thing.The answer you confirmed is "the school and parents" get in trouble with... I understand the parents as a representation of all the parties which involved in. But there are other people might be involved in. Therefore I assume you might write "the school and parents and so on".
