You will need a relay to kick start a backup airconditioning unit. The relay state can be triggered by the dry contact output.
In your application, most customers typically do it temperature based. Indeed you may have a situation where the primary airconditioning unit is no longer powerful enough to cool the room down requiring a secondary unit. By doing it on a temperature level you are actually doing it better then just the power state of the primary unit.
