Abstract

The disclosure provides systems and methods for conveying information between a communicating first device and a second coupled device of a HVAC network. In various embodiments, the method comprises checking a subnet of the HVAC network for both communicating device and a non-communicating device by the communicating first device. The method also comprises determining whether the second coupled device in a non-communicating device. The method further comprises allowing an installer to set parameters of the non-communicating device through employment of a manifest list of features used by the non-communicating device that is accessible by the communicating device.

Claims

1. A method for conveying information between a communicating first device and a second device coupled to said communicating first device of a HVAC network, comprising:

checking a subnet of said HVAC network for a second device by said communicating first device;

determining whether said second device is also a non-communicating device; and

allowing an installer to set parameters of said second device through employment of said first communicating device if said second device is said non-communicating device.

2. The method of claim 1, wherein said non-communicating device is a device that communicates through said first communicating device during an installation instead of directly with an installer.

3. The method of claim 1, wherein said first communicating device conveys said parameters to said second, non-communicating, device after said installer sets said parameters into said communicating device.

4. The method of claim 1, wherein said internal parameters mimic parameters employed in said non-communicating second device to said installer.

5. The method of claim 1, wherein said first communicating device and said second device are coupled to a subnetwork of said HVAC that is controlled by an active subnet controller.

6. The method of claim 1, wherein said second device is an outdoor unit.

7. The method of claim 1, wherein said internal parameters are associated with subnet communications of said second device.

8. An HVAC system, comprising:

a first communicating device; and

a second device coupled to said first communicating device,

wherein said first device can determine if said second device is a communicating device, and

wherein said first device can allow an installer to set internal parameters for said non-communicating device.

9. The system of claim 8, wherein said non-communicating device is a device that communicates through said first communicating device during an installation instead of directly with an installer.

10. The system of claim 8, wherein said first communicating device can conveys said parameters to said second non-communicating device after said installer sets said internal parameters into said first communicating device.

11. The system of claim 8, wherein said internal parameters mimic parameters employed in said non-communicating second device.

12. The system of claim 8, wherein said first communicating device and said second device are coupled to a subnetwork of said HVAC, said subnet controlled by an active subnet controller.

13. The system of claim 8, wherein said second device is an outdoor unit.

14. The method of claim 8, wherein said internal parameters are associated with subnet communications of said second device.

15. An HVAC system, comprising:

a first communicating device; and

a second device coupled to said first communicating device,

wherein said first device can determine if said second device is a communicating device, and

wherein said first device can allow an installer to set internal parameters for said non-communicating device,

wherein said installer sets said internal parameters through employment of an Internet.

16. The system of claim 15, wherein said non-communicating device is a device that communicates through said first communicating device during an installation instead of directly with an installer.

17. The system of claim 15, wherein said first communicating device can conveys said parameters to said second non-communicating device after said installer sets said internal parameters into said first communicating device.

18. The system of claim 15, wherein said internal parameters mimic parameters employed in said non-communicating second device.

19. The system of claim 15, wherein said first communicating device and said second device are coupled to a subnetwork of said HVAC, said subnet controlled by an active subnet controller.

20. The method of claim 15, wherein said internal parameters are associated with subnet communications of said second device.
