Abstract

An interactive system for controlling an HVAC system includes a thermostat for initiating HVAC system operation in a full-capacity or reduced-capacity mode of operation, and a controller for an outside condenser unit having condenser fan and compressor motors. The controller may operate the compressor in a full-capacity or reduced-capacity mode. A controller for an indoor blower unit having a blower fan motor may operate the blower fan motor in a full-capacity or reduced-capacity mode. A communication means is provided for transmitting information between the outside condenser unit controller and indoor blower controller. The indoor blower controller responsively controls blower fan motor operation in a full-capacity or reduced-capacity mode based on the information received from the outdoor unit controller. The outdoor unit controller responsively controls compressor operation in a full-capacity or reduced-capacity mode based on the information received from the indoor blower controller.

Claims

1. An interactive system for controlling at least a heating apparatus in a climate control system having a thermostat and at least one controller for controlling at least a compressor of an air conditioner system, the interactive system comprising:

a heating controller for controlling operation of the heating apparatus; and

a two-wire communication network for transmitting data signals to and from the thermostat, the heating controller and the at least one controller for controlling at least the compressor, where the data signals being transmitted include information identifying a destination controller that a data signal is intended for;

wherein the heating controller is configured to receive data signals that include information about operation of at least one component within the air conditioning system, and the heating controller is configured to modify operation of at least an air circulator blower in response to the information about operation of the at least one component within the air conditioning system.

2. The interactive system of claim 1 wherein the information about operation of the at least one component indicates the air conditioner compressor is only capable of operating at one of a high capacity or a reduced capacity mode of operation, and the heating controller responsively operates the air circulator blower at a capacity level that corresponds to the high capacity or reduced capacity mode of operation of the compressor.

3. The interactive system of claim 1 wherein the information about operation of the at least one component indicates the air conditioner compressor is only capable of operating intermittently, and the heating controller responsively operates the air circulator blower intermittently to correspond to the intermittent compressor operation.

4. The interactive system of claim 1 wherein the heating controller is capable of modifying an operating capacity of the air circulator blower in response to receiving a sensor-transmitted signal that is intended for the thermostat and that includes information about a sensed parameter that is out of a designated range.

5. The interactive system of claim 4 wherein the sensor is a carbon monoxide sensor, and the sensed parameter indicates the presence of carbon monoxide gas at a level predetermined as harmful.

6. An interactive controller for controlling the operation of at least an air circulator blower of a climate control system, the interactive controller comprising:

a connection means for connection to a two-wire network for permitting communication with a thermostat and a controller for controlling an air conditioner compressor, wherein the interactive controller is connected to the thermostat and air conditioner compressor controller only through the connection means to the two-wire network; and

a microprocessor capable of monitoring signals being communicated via the two-wire network, the microprocessor being capable of modifying the operating capacity of the air circulator blower in response to receiving a signal that is addressed to the thermostat or the air conditioner compressor controller, and includes information about an operating parameter of at least one component in the climate control system.

7. The interactive controller of claim 6, capable of reducing the operating capacity of the air circulator blower in response to receiving a signal intended for the thermostat that includes information of a reduced operating capacity of the air conditioner compressor.

8. The interactive controller of claim 7, capable of reducing the operating capacity of the air circulator blower regardless of any signal being sent by the thermostat.

9. An interactive controller for controlling the operation of at least an air circulator blower of a climate control system, the interactive controller comprising:

a connection means for connection to a two-wire network for permitting communication with one or more controllers within the climate control system that are connected to the network; and

a microprocessor capable of monitoring communication signals through the two-wire network upon connection to the two-wire network, and capable of identifying other controllers that are transmitting signals via the two-wire network, where the interactive controller and the network are not configured in a master-slave configuration;

wherein the interactive controller is capable of modifying operation of the operating capacity of the air circulator blower in response to detecting a signal addressed to another controller that includes information about an operating parameter of at least one component in the climate control system.

10. The interactive controller of claim 9, capable of establishing operation of the air circulator blower in response to receiving a signal transmitted by a carbon monoxide sensor that is intended for a communication coordinator controller connected with the network, where the transmitted signal indicates the presence of a harmful level of carbon monoxide gas.

11. The interactive controller of claim 9 wherein the controller for controlling the operation of at least an air circulator blower is capable of reducing the operating capacity of the air circulator blower in response to receiving a signal intended for the thermostat controller that includes information of a reduced operating capacity of the air conditioner compressor.

12. An interactive system for controlling a climate control system, comprising:
