A near field communication device for a heat, ventilation, and air conditioning (HVAC) system including: a near field radio antenna configured to detect and transmit near field communication wireless signals, wherein the near field radio antenna is configured to be attached to a housing of an outdoor unit of the HVAC system; a near field transceiver configured to communicate with a mobile device through the near field radio antenna; and a controller configured to be in electronic communication with an outdoor controller of the outdoor unit.

Alternative near field communication system for HVAC equipment

An HVAC system is disclosed. In some embodiments, the HVAC system comprises a first component comprising a first communication module; a second component comprising a second communication module, the second component configured to communicate with the first component. The second communication module is configured to receive a first set of information over a power line and a second set of information over a communication line.

Methods and systems for data communications in HVAC systems

Provided are embodiments for a heating, ventilation, and air conditioning (HVAC) system for providing sensor information and sensor communication over relay-controlled power line. The system can include a controller of the HVAC system and a first power line converter coupled to the controller. The first power line converter is configured to receive data over a serial bus, convert the data into a communication message for transmission onto a power line, wherein the power line is configured to transmit power and communication messages, and transmit the communication message over the power line. Also provided are embodiments for transmitting and receiving a communication message over relay-controlled power line.
