SYSTEM RECOVERY IN A HEATING, VENTILATION AND AIR CONDITIONING NETWORK
First Claim
1. A method of retrieving data for an active subnet controller of a subnet in an HVAC network, comprising:
- reporting by a device on said subnet of a loss of internal memory settings to said active subnet controller;
recognizing said device by said active subnet controller;
requesting at least one list of parameters from said device by said active subnet controller; and
employing an order of said at least one list of parameters to convey corresponding stored values of these parameters from said active subnet controller to said coupled device.

Abstract
The disclosure provides a system and method of retrieving data for an active subnet controller of a subnet in an HVAC network. In an embodiment, a device on said subnet reports a loss of internal memory settings to said active subnet controller. The device is recognized by the active subnet controller. At least one list of parameters is requested from the device by the active subnet controller. An order of said at least one list of parameters is employed to convey corresponding stored values of these parameters from the active subnet controller to the coupled device.

6. A subnet controller that can retrieve data in an HVAC network, comprising:
-
a receiver than receives from a coupled device an indication of a loss of internal memory settings to said subnet controller in said HVAC; a recognizer configured to recognize said coupled device; a requester configured to requests at least one list of parameters from said device by said subnet controller; and a parameter retriever configured to employ an order of said at least one list of parameters to retrieve corresponding values of these parameters and convey these parameters to said coupled device according to said order. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 19)

15. A method of memory recovery in an HVAC network, comprising:
-
determining whether an entire memory, correlating to stored parameters for a given set of devices, of an active subnet controller in said HVAC network is corrupted; and if said entire memory is corrupted, requiring each device of said given set of devices to convey to said active subnet controller; a) a full feature manifest, and b) a full parameter scan. - View Dependent Claims (16, 17, 18, 20)
