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.
1. An HVAC data processing and communication network, comprising: a first subnet comprising a first subnet controller, a first comfort sensor and a first user interface coupled via a first data bus;a second subnet comprising a second subnet controller, a second comfort sensor and a second user inter
1. An HVAC data processing and communication network, comprising: a first subnet comprising a first subnet controller, a first comfort sensor and a first user interface coupled via a first data bus;a second subnet comprising a second subnet controller, a second comfort sensor and a second user interface coupled via a second data bus; anda switch coupling said first data bus to said second data bus, said switch being configured to decouple said first data bus from said second data bus upon receiving a command from said first subnet controller. 2. The network as recited in claim 1, wherein said first subnet controller is configured to open said switch to isolate said first data bus and said second data bus in the event that said subnet controller detects a bus fault. 3. The network as recited in claim 1, further comprising a gateway configured to send message to a remote entity in the event that said first subnet controller detects a bus fault. 4. The network as recited in claim 1, wherein said first subnet controller is configured to attempt to reconnect said first data bus to said second data bus after the expiration of a predetermined duration. 5. The network as recited in claim 1, wherein said switch receives said command via said first data bus. 6. A method of manufacturing an HVAC data processing and communication network, comprising: configuring a first subnet controller, a first comfort sensor and a first user interface to communicate via a first data bus in a first subnet;configuring a second subnet controller, a second comfort sensor and a second user interface to communicate via a second data bus in a second subnet;coupling said first data bus and said second data bus via a switch configured to decouple said first and second data busses upon receiving a command from said first subnet controller. 7. The method as recited in claim 6, further comprising configuring said first subnet controller to open said switch to isolate said first data bus and said second data bus in the event that said subnet controller detects a bus fault. 8. The method as recited in claim 7, further configuring a gateway to send message to a remote entity in the event that said first subnet controller detects a bus fault. 9. The method as recited in claim 6, wherein said first subnet controller is configured to attempt to reconnect said first data bus to said second data bus after the expiration of a predetermined duration. 10. The method as recited in claim 6, wherein said switch receives said command via said first data bus. 11. The network as recited in claim 1, wherein said first subnet controller is configured to command said switch to isolate said first and second subnets after receiving a startup message via said first data bus. 12. The network as recited in claim 1, wherein said first subnet controller is configured to command said switch to reconnect said first and second subnets upon receiving an appropriately configured message via said first data bus. 13. The method as recited in claim 6, further comprising configuring said first subnet controller to command said switch to isolate said first and second subnets after receiving a startup message via said first data bus. 14. The method as recited in claim 6, further comprising configuring said first subnet controller to command said switch to reconnect said first and second subnets upon receiving an appropriately configured message via said first data bus. 15. An HVAC data processing and communication network bus switch, comprising: a first contact of a switch pole; anda second contact of said switch pole,wherein said switch pole is configured to reversibly connect a first subnet of an HVAC data processing and communication network to a second subnet of said HVAC data processing and communication network, said first subnet including a subnet controller, a comfort sensor and a system device. 16. The bus switch as recited in claim 15, wherein said switch pole is a first switch pole configured to reversibly connect a high polarity of a first data bus associated with said first subnet to a high polarity of a second data bus associated with said second subnet, and further comprising a second switch pole configured to reversibly connect a low polarity of said first data bus with a low polarity of said second data bus. 17. The bus switch as recited in claim 15, further comprising a solenoid configured to isolate said first subnet bus from said second subnet upon command from a subnet controller coupled to said first subnet in the event that said subnet controller determines the existence of a communication failure on a data bus associated with said first subnet. 18. The bus switch as recited in claim 15, wherein said subnet controller is configured to command said bus switch to isolate said first and second subnets after receiving a startup message via a data bus associated with said first subnet. 19. The bus switch as recited in claim 15, wherein said subnet controller is configured to reconnect said first and second subnets after receiving an appropriately configured message via a first data bus associated with said first subnet.
