摘要

The disclosure provides an a system and method of backing up operating control data about a device connected to a controller in a network. In an embodiment, the network includes a storage system for the data about the device is in the controller; a first subsystem for determining that the data should be transferred to the device; and a second subsystem for transferring the data to the device for use.

主权项

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.
