In my place of work

In my place of work, the main open-plan office office and the rec room / canteen each have two heating / AC units linked fo a single controller.

Unfortunately, the arbitration logic in the controller is all broken. If one end of the room is at 19 degrees and the other end is at 23 degrees, and the controller is set for 21 degrees, both units come on to heat until the cooler end of the room reaches 21 degrees -- and the hotter end is now nearer 27. If the mode is then changed from heating to cooling, both units come on to cool until the hotter end gets down to 19 degrees.

The controllers also have a nasty habit of crashing and restarting themselves if the temperature in either end of the room is below 19 or above 23 degrees .....
