Identification of HVAC systems in a communication network
First Claim
1. A process for assigning values of identifications to networked HVAC systems within a communication network wherein the HVAC systems within the network can be identified and communicated with by other devices within the network using assigned values of network identifications to the HVAC systems, said process comprising the steps of:
- transmitting a signal containing the value of a network identification to be assigned to a particular HVAC system in a predetermined signal format;
receiving the signal containing the value of the network identification at a receiver within the particular HVAC system that is to be assigned the network identification;
forwarding the value of the network identification to a programmed processor associated with the receiver within the particular HVAC system that is to be assigned the network identification; and
assigning the value of the network identification to the HVAC system by storing the value of the network identification in a non-volatile memory associated with the programmed processor so that the value stored in the memory can thereafter be used by the programmed processor to identify the particular HVAC system within the network.

Abstract
An HVAC system is assigned a network identification for subsequent use within a communication network upon receipt of a formatted signal containing the network identification. The HVAC system stores the network identification in nonvolatile memory. The HVAC system also preferably stores a verification image of the communicated network identification so that any reading back of the network identification can be validated through comparison with the stored verification image.

13. The process of clam 12 further comprising the step of:
-
reading both the value of the network identification and the value of the verification image from the at least one further addressable location in the nonvolatile memory set aside for storing a value of the network identification following an outage of electrical power to the HVAC system when the read values of the network identification and the verification image from the previously read memory location do not have the predetermined mathematical relationship dictated by said step of transforming the value of the network identification to the verification image; comparing the values of the network identification and verification image read from the at least one further addressable location to determine whether the value of the verification image has the predetermined mathematical relationship with respect to the value of the network identification dictated by said step of transforming the value of the network identification to the verification image; and setting a network identifier variable equal to the value of the network identification read from the at least one further addressable location when the read values of the network identification and verification image have the predetermined mathematical relationship dictated by said step of transforming the value of the network identification to the verification image whereby the value of the network identifier variable can be used by the processor in identifying the particular HVAC system within the network. - View Dependent Claims (14)

18. A communications network comprising a plurality of HVAC devices connected to a communications bus wherein at least some of the HVAC devices receive communications over the communications bus from other devices connected to the communications bus wherein at least one of the HVAC devices receiving the communications comprises:
-
a receiver for receiving a communicated network identification of the HVAC device; a processor for processing the network identification of the HVAC device; and a nonvolatile memory associated with the processor for storing the processed network identification of the HVAC device so that the processed network identification of the HVAC device can be thereafter used by devices connected to the communications bus to address the HVAC device when communication is to occur with the HVAC device over the communication bus. - View Dependent Claims (19)
