Method of controlling equipment in a heating, ventilation and air conditioning network
First Claim
1. An HVAC data processing and communication network for an HVAC system including a heat pump, a communicating indoor unit and an auxiliary heater, said communication network comprising:
- a sensor configured to detect a fault condition associated with operation of a demand unit;
a local controller associated with said demand unit and configured to communicate via said network to
1) control said demand unit,
2) receive sensor data from said sensor, and
3) transmit said sensor data over said network; and
a network controller configured to receive said sensor data via said network, to generate an alert in the event that said sensor data indicates said fault condition, to detect an operation of said auxiliary heater during a cooling mode of said communicating indoor unit and to disable said auxiliary heater in the event that said operation is detected, said cooling mode being an operating mode of said HVAC system wherein said communicating indoor unit cooperates with said heat pump to provide cooling.

Abstract
The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes a sensor and a local controller. The sensor is configured to detect a fault condition associated with operation of a demand unit. The local controller, associated with the demand unit, is configured to receive sensor data from the sensor and to communicate the sensor data over the network. A network controller is configured to receive the sensor data via the communication network and to generate an alert in the event that the sensor data indicates the fault condition.
