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.

Claims21

Dependent claims

A retrofittable, single family home, room-by-room temperature controlling system comprising:

a hot air and air conditioning furnace system with a plurality of output ducts extending to rooms of a building;
controllable output register assemblies or vent assemblies at the outlet of each duct into the room, said registers including, as a part of the register assembly, electrically operable means for selectively opening and sealing the output from the register;
a central controller for controlling the furnace system and for operating the registers in each room to control the heating and cooling of each room individually;
a master controller for selecting temperature conditions remotely for each room and for sending signals to the central controller indicating the selected temperature conditions;
thermostat units in each room indicating for each room, the actual temperature, the set temperature, and the desired mode, including (a) heat, (b) air conditioning, (c) fan, and (d) off, conditions, and said thermostat units further including switch controls for setting locally the mode and the desired temperature;
said master controller and said thermostat units being electrically coupled to said central controller;
and
said central controller including means responsive to signals from said master controller and from said thermostat units for controlling the heating and air conditioning furnace unit, and for opening and closing the registers and/or vents in each room.

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

a hot air and air conditioning furnace system with a plurality of output ducts extending to rooms of a building;
controllable output register assemblies or vent assemblies at the outlet of each duct into the room, said registers including, as a part of the register assembly electrically operable means for selectively opening and sealing the output from the register;
a central controller for controlling the furnace system and for operating the registers in each room to control the heating and cooling of each room individually;
thermostat units in each room for sensing room temperature, said thermostat units being electrically coupled to said central controller;
and
said central controller including means responsive to signals from said thermostat units for controlling the heating and air conditioning furnace unit, and for opening and closing the registers and/or vents in each room;
wherein said controllable output register assemblies or vent assemblies, said thermostat units, and said central controller include means for receiving and transmitting operating instructions and responses via radio-type signals.

4 more elements

A retrofittable, building, room-by-room temperature controlling system comprising:

a hot air and air conditioning furnace system with a plurality of output ducts extending to rooms of said building;
controllable output register assemblies at the outlet of each duct into the room, said controllable output register assemblies having retrofittable means for fitting the register assemblies to any duct opening, said register assemblies including, as a part of the register assembly, electrically operable means for selectively opening and sealing the output from the register;
thermostat units in each room for sensing room temperature, and said thermostat units further including switch controls for setting locally mode and desired temperature;
and
a central controller including means responsive to signals from the thermostat units, said central controller including means for controlling the furnace system, said central controller further including means for electrically controlling said controllable register assemblies in each room.
