First Claim
Patent Images
1. A system for restoring operating control data to a networked heating ventilation and air conditioning (HVAC) device coupled to an HVAC system controller in a network, comprising:
- a storage system located within the controller and configured to store the operating control data;
a first subsystem configured to determine whether the operating control data in the storage system and in the HVAC device are corrupted; and
a second subsystem configured to convey the operating control data in the HVAC device to the storage system when only the operating control data in the storage system is corrupted and to convey the operating control data in the storage system to the HVAC device when only the operating control data in the HVAC device is corrupted,wherein the HVAC device is configured to restore the operating control data therein with a default value and convey the default value to the storage system when both the operating control data in the storage system and the HVAC device are corrupted.

19. An heating ventilation and air conditioning (HVAC) subnet controller configured to store back-up information for a networked HVAC device of a networked HVAC system subnet, comprising:
-
a device memory storage configured to store the back-up information for a first HVAC device coupled to the subnet of the HVAC system; and a memory selector configured to; a) select a subset of the back-up information; and b) convey the subset of the back-up information to a second HVAC device coupled to the subnet when operating data of the second device is corrupted and the subset of the back-up information is not corrupted, wherein the second HVAC device is configured to restore the operating control data with to a default value and convey the default value to the subnet controller when both the operating control data and the subset of the back-up information are corrupted. - View Dependent Claims (20)
