1. An HVAC data processing and communication network, comprising:
- a user interface;
a first subnet controller configured to operate with a first zone of said network with a first program schedule, said first zone including said user interface, said first subnet controller, and a plurality of comfort sensors, wherein said first subnet controller is configured to control an operation of a demand unit associated with said first zone based on input received from two or more of said plurality of comfort sensors;
a second subnet controller configured to operate with a second zone of said network with a second program schedule;
wherein the first and second subnet controllers are configured to operate both the first and second zones upon detecting a failure of the other one of the first or second subnet controllers, and to override said first and second schedules to operate said first and said second zones according to settings received from said user interface.

Abstract
The disclosure provides an HVAC data processing and communication network. In an embodiment, the network includes a user interface, a first subnet controller and a second subnet controller. The first subnet controller is configured to operate with a first zone of the network with a first program schedule. The second subnet controller is configured to operate with a second zone of the network with a second program schedule. The second subnet controller is further configured to override the first and second schedules to operate the first and the second zones according to hold settings received from the user interface.
