Contention - Where two or more separate automatic control systems operating in the same space, fight each other. Independent, each may operate in a different mode simultaneously. For example, one system senses rising temperature and delivers more cooling. Whilst the another control system sensing the dropping temperature delivers more heat. Wasting an enormous amount of energy.
