Abstract

A retrofittable heating and air conditioning system for a single family dwelling including a heater and air conditioning furnace system connected to individual zones of a building by a series of output ducts. Each opening of a duct to an individual zone may have a unique, fully sealing, controllable output register assembly. Also, in each zone is a thermostat for sensing the zone temperature and for providing a means for the user to control the temperature of that zone. The system further includes a master controller with such temperature controlling features as a universal zone controller, individual zone controllers, and a timer. Finally, the system includes a central controller for controlling the register assemblies and the air conditioning, heating, and fan with respect to instructions set by the individual zone registers and the master controller.

said central controller further including;

means for comparing the system status with the desired mode of each remote unit;

means for changing the system status to the desired mode of each remote unit if they are different, and means for broadcasting the system status to all remote units;

means for actuating the register units according to the actual temperature of the room and the system status; and

means for actuating the furnace system mode of operation to correspond to the system status.

13. A retrofittable temperature controlling system for a multi-room building, comprising:
