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; and
a 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.

Abstract
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.
