Abstract
The disclosure provides various systems and methods for conveying information between a communicating first device and a second coupled device of a HVAC network. In various embodiments, a checking of a subnet of the HVAC network for both communicating device and a non-communicating device by the communicating first device occurs. It is determined whether the second coupled device in a non-communicating device. An installer is allowed 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.
Claims20
A method for commissioning a first device that can communicate with a second device in a HVAC network, comprising:
- entering a commissioning process by said first device of a subnet of said HVAC network;
- reading an outdoor feature manifest by said first device;
- setting a parameter validity, as determined by said outdoor feature manifest, by said first device;
- setting an internal parameter value by said device as determined by said outdoor feature manifest;
- and
- informing an installer on validity and value of said parameter.
An HVAC system, comprising:
- a first device of said HVAC system;
- a second device of said HVAC system;
- a subnet of said HVAC system coupled to said first device and said second device;
- an outdoor feature manifest readable by said first device after said first device enters a commissioning process;
- a parameter validity indicia as determined by said outdoor feature manifest by said first device;
- an internal parameter value of said device;
- and
- an output employable to convey to an installer:
- a) said parameter validity indicia, and
- b) said value of said internal parameter.
An HVAC system, comprising:
- a first device;
- an interface, coupled to said first device, that can send to said first device:
- a) a parameter value change message, and
- b) a new value of an installer parameter,
- wherein said first device can:
- a) store said parameter in a memory of said first device if said parameter update is within an allowed range, and
- b) send said parameter to said interface device;
- and
- an active subnet controller, coupled to said interface, that can receive said updated parameter,
- wherein said parameter value change message is received over an Internet.
