An automatic master slave system and approach for coordinated control of a parameter, for example, a heating, ventilation and air conditioning condition, in an area of multiple spaces controlled by room controllers. Changing a layout of a zone/area in a building such as moving, adding or removing a door, increasing or splitting size of a room through movable walls, or by permanently removing partitions, changing offices to a conference room or vice versa, may occur. A size of a room may be altered within minutes, according to customer demand. For instance, rooms may be converted into a single room by removing partitions. The controllers that were controlling temperatures of the rooms independently earlier, may convert automatically into a master-slave configuration and now work together to control a larger room. If the large room is split into multiple rooms, the controllers may automatically revert to their previous configuration.

Automatic master-slave system and approach

A flexible link system and approach for dynamically switching among wall modules of various types without re-engineering an associated controller application. Some of the types of wall modules may incorporate those of Sylk, BACnet and conventional types. A wall module type switching mechanism may incorporate a controller incorporating an application having a flexible link for the connection of wall modules of various types. The flexible link may enable a number of data points of the application to be applicable to various types of wall modules in that switching from a wall module of one type to a wall module of another type does not necessarily require another set of data points in the application.
