摘要:
The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes configuring a first system device and a subnet controller. The first system device is configured to receive an initial value of a specified dependent parameter. The subnet controller is configured to determine that a value of said specified parameter has been changed to a modified value after said first system device receives said initial value. The subnet controller is further configured to send to said first system device, in response to said determining, a message updating said specified parameter with said modified value.

The disclosure provides an auxiliary controller of a HVAC system, a method of manufacturing a HVAC system, a method of starting a HVAC system and a HVAC system. In one embodiment, the HVAC system includes: (1) a main system controller having a main non-volatile memory and configured to direct operation of the HVAC system and store main controller application information associated therewith on the main non-volatile memory (2) an auxiliary controller having (2A) an interface coupled to the main system controller and configured to communicate therewith, (2B) a processor, coupled to the interface and configured to direct the operation of a component of the HVAC system and (2C) an auxiliary non-volatile memory configured to receive a copy of the main controller application information via the interface and store the main controller application information thereon.
摘要:
A system to backup data about a device in a network is disclosed. In a particular embodiment, the system includes a storage system for the data about the device in a 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.
摘要:
A system and method for reducing the time for charging a filter in a liquid dispensing system, such as one utilizing a positive displacement pump, is disclosed. The filter is located at the input side of the pump between the source of the liquid and the pump. In order to prevent air from the filter from entering the pump a reservoir is provided between the filter and the source of the fluid. Air from the filter is vented into the reservoir through a vent tube. A vacuum is used to draw air from the filter and, through the reservoir.

The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes a user interface and a system device. The user interface is configured to publish a privilege request message to a data bus. The system device is configured to receive messages via the data bus and to store configuration data in nonvolatile memory. The system device is further configured to enable a privileged operating mode not normally available to a user of the network in response to the privilege request message.
摘要:
An HVAC data processing and communication network includes a subnet controller and at least one demand unit. A bus interface device associated with the demand unit is configured to receive a demand message from the subnet controller over the network. The bus interface device controls an operation of said demand unit in response to said demand message.
摘要:
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.
