Abstract

Control devices for configuring heating, ventilating, air conditioning, and cooling (HVAC) systems are provided. The control devices are designed to detect operational parameters of units within HVAC systems and present system configurations consistent with the detected parameters. In response to user selection of a system configuration, the control device may apply the system configuration to the HVAC system and may reconfigure settings of control circuits within system units. The system configurations presented by the control device may correspond to wiring diagrams that are familiar to service technicians. Methods of configuring HVAC systems with the control devices are also provided.

Claims

1. A method for configuring a heating, ventilating, air conditioning, or cooling system, the system including at least one HVAC unit communicatively coupled to a control device for the exchange of control signals, the HVAC unit including a control circuit, the method comprising:

receiving a user input of a system identifier from a plurality of system identifiers that are compatible with properties of the system and the control circuit of the at least one HVAC unit, wherein each system identifier specifies a wired system arrangement of hardwired connections within the system, and wherein the hardwired connections define an operational configuration of the system; and

digitally configuring one or more components of the system based upon the received user input of the system identifier to create digital communication paths representing the hardwired connections to set the system to the operational configuration, wherein the one or more components comprise the control circuit of the HVAC unit, or the control device, or both, and wherein at least one of the one or more components comprises a replacement component.

2. The method of claim 1, comprising:

transmitting digital signals to the control circuit to detect components communicatively coupled to the control circuit; and

presenting to a user a plurality of system identifiers compatible with the detected components.

3. The method of claim 2, wherein the detected components include at least one of a motor, an electronic expansion valve, a reversing valve, and a compressor.

4. The method of claim 1, comprising:

storing the system identifier within a memory of the control device; and

transmitting the system identifier to the HVAC unit for storage within the HVAC unit.

5. The method of claim 4, wherein the replacement component comprises a replacement control device, and comprising:

retrieving the system identifier from the HVAC unit; and

configuring the replacement control device based upon the retrieved system identifier.

6. The method of claim 4, wherein the replacement component comprises a replacement HVAC unit that includes a replacement control circuit, and comprising:

retrieving the system identifier from the control device; and

configuring the replacement HVAC unit based upon the retrieved system identifier.

7. The method of claim 1, comprising providing for display, in response to receiving the user input, a graphical representation of the wired system arrangement that depicts the hardwired connections.

8. The method of claim 7, comprising:

displaying, on a touch screen, a graphical representation of the wired system arrangement that depicts the hardwired connections; and

receiving a user input through the touch screen that moves one of the hardwired connections to a new location within the wired system arrangement.

9. A control device for a heating, ventilating, air conditioning, or cooling system, the system including one or more indoor units and one or more outdoor units coupled to one another to implement a refrigeration cycle and coupled to the control device for the exchange of control signals, each of the indoor and outdoor units including a respective control circuit, the control device comprising:

a processor;

a user interface for receiving a user input selecting a system identifier from a plurality of system identifiers that are compatible with properties of the control circuits of the indoor and outdoor units, wherein each system identifier specifies a wired system arrangement of hardwired connections within the system, and wherein the hardwired connections define an operational configuration of the system; and

a computer readable storage medium having configuration code encoded thereon, wherein the configuration code is executable by the processor and comprises code for;

discovering the properties of the control circuits of the indoor and outdoor units;

determining the plurality of system identifiers based on the properties;

digitally configuring a replacement control circuit for at least one of the respective control circuits to create digital communication paths representing the hardwired connections to set the system to the operational configuration corresponding to the selected system identifier.

10. The control device of claim 9, wherein the operational configurations corresponding to the system identifiers include at least one of a heat pump providing two stages of cooling and three stages of heating, or an air conditioner providing modulating cooling and a furnace providing modulating heating.

11. The control device of claim 9, wherein the computer readable storage medium comprises code for selecting a default system identifier and at least one alternative system identifier from the plurality of system identifiers.

12. The control device of claim 9, wherein the user interface includes a touch screen.

13. The control device of claim 9, wherein the user interface includes a port for receiving a solid state memory circuit.

14. The control device of claim 9, wherein the user interface includes a wireless link.

15. The control device of claim 9, wherein the properties identify types of equipment included within the indoor and outdoor units, types of heating or cooling employed by the indoor and outdoor units, or a number of stages within the indoor and outdoor units, or a combination thereof.
